  Creating Symbols An important step in creating a Ladder Program is the definition of those PLC data areas that are to be referenced by the program. It is possible to skip this step, and use addresses directly within the program. It is better, however, to create symbolic names for the addresses so that the programs become more readable and maintainable.

Use manual settings to create flexible data links to meet the requirements of the individual system (e.g., efficient utilization of memory, restrictions on allocated addresses, etc.).

• Page 335
  Automatic settings can be used for simple data exchanges involving fixed allocations, when all nodes are set for the same send size and the same data is to be shared among all nodes in order of node address. Using a Programming Device (such as the CX-Programmer or a Programming Console), set the data exchange method in the DM parameter area of the startup node.

  Particularly, it allows monitoring of communications. For example, a SYSMAC WAY connection configured at 9,600 baud, 7 data bits, even parity and 2 stop bits, transmits 10 bits per byte at 9,600 bits per second; this means that the absolute maximum throughput of the cable is 960 bytes per second. Requesting or transmitting data at this rate results in slow response times.

• Page 488
  To refresh the Performance Monitor tool details, select the Refresh Now option from the View menu. The performance Monitor tool can be hidden from the desktop by minimising the window, and can be hidden from the taskbar in its minimised state by selecting Hide on Minimise option from the Options menu.

!WARNING It is extremely important that a PLC and all PLC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-men- tioned applications.

3 Safety Precautions

!WARNING Confirm safety sufficiently before transferring I/O memory area status from the CX-Programmer Ver. 5.0 to the actual CPU Unit. The devices connected to Output Units may malfunction, regardless of the operating mode of the CPU Unit. Caution is required in respect to the following functions.

•Transferring from the CX-Programmer to real I/O (CIO Area) in the CPU Unit using the PLC Memory Window.

•Transferring from file memory to real I/O (CIO Area) in the CPU Unit using the Memory Card Window.

!Caution Variables must be specified either with AT settings (or external variables), or the variables must be the same size as the data size to be processed by the instruction when specifying the first or last address of multiple words in the instruction operand.

1.If a non-array variable with a different data size and without an AT setting is specified, the CX-Programmer will output an error when compiling.

2.Array Variable Specifications

•When the size to be processed by the instruction operand is fixed:

The number of array elements must be the same as the number of elements to be processed by the instruction. Otherwise, the CX-Programmer will output an error when compiling.

•When the size to be processed by the instruction operand is not fixed: The number of array elements must be greater than or the same as the size specified in the other operands.

•If the other operand specifying a size is a constant, the CX-Program- mer Ver. 5.0 will output an error when compiling.

•If the other operand specifying a size is a variable, the CX-Programmer Ver. 5.0 will not output an error when compiling, even if the size of the array variable is not the same as that specified by the other operand (variable). A warning message, however, will be displayed. In particular, if the number of array elements is less than the size specified by the other operand (e.g., the size of the instruction operand is 16, and the number of elements registered in the actual variable table is 10), the instruction will execute read/write processing for the area that exceeds the number of elements. For example, read/write processing will be executed for the 6 words following those for the number of elements registered in the actual variable table. If these words are used for other instructions (including internal variable allocations), unexpected operation will occur, which may result in serious accidents.

Check that the system will not be adversely affected if the size of the variable specified in the operand is less than the size in the operand definition before starting PLC operations.

!Caution Confirm safety at the destination node before transferring a program to another node or changing contents of the I/O memory area. Doing either of these without confirming safety may result in injury.

!Caution Execute online editing only after confirming that no adverse effects will be caused by extending the cycle time. Otherwise, the input signals may not be readable.

!Caution Confirm safety sufficiently before monitoring power flow and present value status in the Ladder Section Window or when monitoring present values in the Watch Window. If force-set/reset or set/reset operations are inadvertently performed by pressing short-cut keys, the devices connected to Output Units may malfunction, regardless of the operating mode of the CPU Unit.

4 Application Precautions

Observe the following precautions when using the CX-Programmer.

•User programs cannot be uploaded to the CX-Programmer.

•Observe the following precautions before starting the CX-Programmer.

•Exit all applications not directly related to the CX-Programmer. Particularly exit any software such as screen savers, virus checkers, E-mail or other communications software, and schedulers or other applications that start up periodically or automatically.

•Disable sharing hard disks, printers, or other devices with other computers on any network.

•With some notebook computers, the RS-232C port is allocated to a modem or an infrared line by default. Following the instructions in documentation for your computer and enable using the RS-232C port as a normal serial port.

•With some notebook computers, the default settings for saving energy do not supply the rated power to the RS-232C port. There may be both Windows settings for saving energy, as well as setting for specific computer utilities and the BIOS. Following the instructions in documentation for your computer, disable all energy saving settings.

•Do not turn OFF the power supply to the PLC or disconnect the connecting cable while the CX-Programmer is online with the PLC. The computer may malfunction.

•Confirm that no adverse effects will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.

•Changing the operating mode of the PLC.

•Force-setting/force-resetting any bit in memory.

•Changing the present value of any word or any set value in memory.

•Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected operation.

•When online editing is performed, the user program and parameter area data in CS1-H, CJ1-H, and CJ1M CPU Units is backed up in the built-in flash memory. The BKUP indicator will light on the front of the CPU Unit when the backup operation is in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator is lit. The data will not be backed up if power is turned OFF. To display the status of writing to flash memory on the CX-Programmer, select Display dialog to show PLC Memory Backup Status in the PLC properties and then select Windows — PLC Memory Backup Status from the View Menu.

•Programs including function blocks (ladder programming language or structured text (ST) language) can be downloaded or uploaded in the same way as standard programs that do not contain function blocks. Tasks including function blocks, however, cannot be downloaded in task units (uploading is possible).

•If a user program containing function blocks created on the CX-Program- mer Ver. 5.0 or later is downloaded to a CPU Unit that does not support function blocks (CS/CJ-series CPU Units with unit version 2.0 or earlier), all instances will be treated as illegal commands and it will not be possible to edit or execute the user program.

•If the input variable data is not in boolean format, and numerical values only (e.g., 20) are input in the parameters, the actual value in the CIO Area address (e.g., 0020) will be passed. Therefore, be sure to include an &, #, or +, — prefix before inputting the numerical value.

•Addresses can be set in input parameters, but the address itself cannot be passed as an input variable. (Even if an address is set as an input parameter, the value passed to the function block will be that for the size of data in the input variable.) Therefore, an input variable cannot be used as the operand of the instruction in the function block when the operand specifies the first or last of multiple words. Use an internal variable with an AT setting. Alternatively, specify the first or last element in an internal array variable.

•Values are passed in a batch from the input parameters to the input variables before algorithm execution (not at the same time as the instructions in the algorithm are executed). Therefore, to pass the value from a parameter to an input variable when an instruction in the function block algorithm is executed, use an internal variable or external variable instead of an input variable. The same applies to the timing for writing values to the parameters from output variables.

•Always use internal variables with AT settings in the following cases.

•The addresses allocated to Basic I/O Units, Special I/O Units, and CPU Bus Units cannot be registered to global symbols, and these variables cannot be specified as external variables (e.g., the data set for global variables may not be stable).

•Use internal variables when Auxiliary Area bits other than those preregistered to external variables are registered to global symbols and these variables are not specified as external variables.

•Use internal variables when specifying PLC addresses for another node on the network: For example, the first destination word at the remote node for SEND(090) and the first source word at the remote node for RECV(098).

•Use internal variables when the first or last of multiple words is specified by an instruction operand and the operand cannot be specified as an internal array variable (e.g., the number of array elements cannot be specified).

SECTION 1

Introduction

This section introduces the function block functionality of the CX-Programmer and explains the features that are not contained in the non-function block version of CX-Programmer.

1-1 Introducing the Function Blocks

1-1-1 Overview and Features

The CX-Programmer Ver. 5.0 is a Programming Device that can use standard IEC 61131-3 function blocks. The CX-Programmer Ver. 5.0 function block function is supported for CS/CJ-series CPU Units with unit version 3.0 or later and has the following features.

•User-defined processes can be converted to block format by using function blocks.

•Function block algorithms can be written in the ladder programming language or in the structured text (ST) language. (See note.)

•When ladder programming is used, ladder programs created with non- CX-Programmer Ver. 4.0 or earlier can be reused by copying and pasting.

•When ST language is used, it is easy to program mathematical processes that would be difficult to enter with ladder programming.

Note The ST language is an advanced language for industrial control (primarily Programmable Logic Controllers) that is described in IEC 61131-3. The ST language supported by CX-Programmer conforms to the IEC 61131-3 standard.

•Function blocks can be created easily because variables do not have to be declared in text. They are registered in variable tables.

A variable can be registered automatically when it is entered in a ladder or ST program. Registered variables can also be entered in ladder programs after they have been registered in the variable table.

•A single function block can be converted to a library function as a single file, making it easy to reuse function blocks for standard processing.

•A program check can be performed on a single function block to easily confirm the function block’s reliability as a library function.

•Programs containing function blocks (ladder programming language or structured text (ST) language) can be downloaded or uploaded in the same way as standard programs that do not contain function blocks. Tasks containing function blocks, however, cannot be downloaded in task units (uploading is possible).

•One-dimensional array variables are supported, so data handling is easier for many applications.

Note The IEC 61131 standard was defined by the International Electrotechnical Commission (IEC) as an international programmable logic controller (PLC) standard. The standard is divided into 7 parts. Specifications related to PLC programming are defined in Part 3 Textual Languages (IEC 61131-3).

Introducing the Function Blocks Section 1-1

Note The structured text (ST language) conforms to the IEC 61131-3 standard, but CX-Programmer Ver. 5.0 supports only assignment statements, selection statements (CASE and IF statements), iteration statements (FOR, WHILE, REPEAT, and EXIT statements), RETURN statements, arithmetic operators, logical operators, comparison functions, numeric functions, and comments. For details, refer to Appendix B Structured Text (ST Language) Specifications.

1-1-3 Files Created with CX-Programmer Ver. 5.0

Each function block can be stored in a separate definition file (.cxf).

1-1-4 CX-Programmer Ver. 5.0 Function Block Menus

The following tables list CX-Programmer Ver. 5.0 menus related to function blocks. For details on all menus, refer to the CX-Programmer Ver. 5.0 Operation Manual (W437).

1-2 Function Blocks

1-2-1 Outline

A function block is a basic program element containing a standard processing function that has been defined in advance. Once the function block has been defined, the user just has to insert the function block in the program and set the I/O in order to use the function.

As a standard processing function, a function block does not contain actual addresses, but variables. The user sets addresses or constants in those variables. These address or constants are called parameters. The addresses used by the variables themselves are allocated automatically by the CX-Pro- grammer for each program.

With the CX-Programmer, a single function block can be saved as a single file and reused in other PLC programs, so standard processing functions can be made into libraries.

1-2-2 Advantages of Function Blocks

1-2-3 Function Block Structure

1. Algorithm

Standardized programming is written with variable names rather than real I/O memory addresses. In the CX-Programmer, algorithms can be written in either ladder programming or structured text.

Note Instances are managed by names. More than one instance with the same name can also be inserted in the program. If two or more instances have the same name, they will use the same internal variables. Instances with different names will have different internal variables.

For example, consider multiple function blocks that use a timer as an internal variable. In this case all instances will have to be given different names. If more than one instance uses the same name, the same timer would be used in multiple locations, resulting in duplicated use of the timer.

If, however, internal variables are not used or they are used only temporarily and initialized the next time an instance is executed, the same instance name can be used to save memory.

instance_A

TIMER_FB

Function Block Definition

TIMER_FB

instance_A

TIMER_FB

Use different internal variables.

instance_B TIMER_FB

Set the constants or input source addresses from which to pass data.

Set the constant or output destination address to which to pass data.

Even if an input source address (i.e., an input parameter) or an output destination address (i.e., an output parameter) is a word address, the data that is passed will be the data in the form and size specified by the variable data type starting from the specified word address.

Program

Instance of Function Block Definition A

Examples:

If m is type WORD, one word of data from D100 will be passed to the variable.

If n is type DWORD, two words of data from D200 and D201 will be passed to the variable.

If k is type LWORD, four words of data from the variable will be passed to the D300 to D303.

Note (1) Only addresses in the following areas can be used as parameters: CIO Area, Auxiliary Area, DM Area, EM Area (banks 0 to C), Holding Area, and Work Area.

The following cannot be used: Index and Data Registers (both direct and indirect specifications) and indirect addresses to the DM Area and EM Area (both in binary and BCD mode).

(2)Local and global symbols in the user program can also be specified as parameters. To do so, however, the data size of the local or global symbol must be the same as the data size of the function block variable.

(3)When an instance is executed, input values are passed from parameters to input variables before the algorithm is processed. Output values are passed from output variables to parameters just after processing the algorithm. If it is necessary to read or write a value within the execution cycle of the algorithm, do not pass the value to or from a parameter. Assign the value to an internal variable and use an AT setting (specified addresses).

!Caution If an address is specified in an input parameter, the values in the address are passed to the input variable. The actual address data itself cannot be passed.

!Caution Parameters cannot be used to read or write values within the execution cycle of the algorithm. Use an internal variable with an AT setting (specified addresses). Alternatively, reference a global symbol as an external variable.

■ Reference Information

A variety of processes can be created easily from a single function block by using parameter-like elements (such as fixed values) as input variables and changing the values passed to the input variables for each instance.

Example: Creating 3 Instances from 1 Function Block Definition

Cyclic task 1

CASCADE

Some precautions are required when using the same memory area. For example, if the same instance containing a timer instruction is used in more than one program location, the same timer number will be used causing coil duplication, and the timer will not function properly if both instructions are executed.

Registration of Instances Each instance name is registered in the global symbol table as a file name.

Program

c

The instance is registered in the global symbol table with the instance name as the symbol name.

1-3 Variables

1-3-1 Introduction

In a function block, the addresses (see note) are not entered as real I/O memory addresses, they are all entered as variable names. Each time an instance is created, the actual addresses used by the variable are allocated automatically in the specified I/O memory areas by the CX-Programmer. Consequently, it isn’t necessary for the user to know the real I/O memory addresses used in the function block, just as it isn’t necessary to know the actual memory allocations in a computer. A function block differs from a subroutine in this respect, i.e., the function block uses variables and the addresses are like “black boxes.”

Note Constants are not registered as variables. Enter constants directly in instruction operands.

•Ladder programming language: Enter hexadecimal numerical values after the # and decimal values after the &.

•Structured text (ST language): Enter hexadecimal numerical values after 16# and enter decimal numerical values as is.

Exception: Enter directly or indirectly specified addresses for Index Registers IR0 to IR15 and Data Registers DR0 to DR15 directly into the instruction operand.

1-3-2 Variable Usage and Properties

Outputs: Output variables can output data to output parameters outside of the instance. The default output variable is an ENO (Enable Out) variable, which passes the instance’s execution status.

Externals: External variables are either system-defined variables registered in advance with the CX-Programmer, such as the Condition Flags and some Auxiliary Area bits, or user-defined global symbols for use within instances.

For details on variable usage, refer to the section on Variable Type (Usage) under Variable Definitions in 2-1-2 Function Block Elements.

The following table shows the number of variables that can be used and the kind of variable that is created by default for each of the variable usages.

1-3-3 Variable Properties

1-3-4 Variable Properties and Variable Usage

The following table shows which properties must be set, can be set, and cannot be set, based on the variable usage.

Note Inputs can be set as initial values, but the value of the actual input parameter will be given priority.

1-3-5 Internal Allocation of Variable Addresses

When an instance is created from a function block definition, the CX-Program- mer internally allocates addresses to the variables. Addresses are allocated to all of the variables registered in the function block definition except for variables that have been assigned actual addresses with the AT Settings property.

Setting Internal Allocation The user sets the function block instance areas in which addresses are allo- Areas for Variables cated internally by the system. The variables are allocated automatically by

the system to the appropriate instance area set by the user.

Function Block Holding Area Words (H512 to H1535)

1-4 Converting Function Block Definitions to Library Files

A function block definition created using the CX-Programmer can be stored as a single file known as a function block definition file with filename extension *.cxf. These files can be reused in other projects (PLCs).

1-5 Usage Procedures

Once a function block definition has been created and an instance of the algorithm has been created, the instance is used by calling it when it is time to execute it. Also, the function block definition that was created can be saved in a file so that it can be reused in other projects (PLCs).

1-5-1 Creating Function Blocks and Executing Instances

The following procedure outlines the steps required to create and execute a function block.

1,2,3… 1. First, create the function block definition including the algorithm and variable definitions in ladder program or ST language. Alternatively, insert a function block library file that has been prepared in advance.

Note (a) Create the algorithm entirely with variable names.

(b)When entering the algorithm in ladder programming language, project files created with versions of CX-Programmer earlier than Ver. 5.0 can be reused by reading the project file into the CX-Pro- grammer Ver. 5.0 and copying and pasting useful parts.

2.When creating the program, insert copies of the completed function block definition. This step creates instances of the function block.

3.Enter an instance name for each instance.

4.Set the variables’ input source addresses and/or constants and output destination addresses and/or constants as the parameters to pass data for each instance.

5.Select the created instance, select Function Block Memory — Function Block Memory Allocation from the PLC Menu, and set the internal data area for each type of variable.

6.Transfer the program to the CPU Unit.

7.Start program execution in the CPU Unit and the instance will be called and executed if their input conditions are ON.

1-5-2 Reusing Function Blocks

Use the following procedure to save a function block definition as a file and use it in a program for another PLCs.

1,2,3… 1. Select the function block that you want to save and save it as a function block definition file (*.cxf).

2.Open the other PLC’s project and open/read the function block definition file (*.cxf) that was saved.

3.Insert the function block definition in the program when creating the new program.
