Chapter 1. Programming Site Data

1.1Introduction

The Model XMT868i flow transmitter must be properly installed and programmed, as described in the Startup Guide, before it can provide accurate flow rate measurements. After completing the installation and initial setup, use this chapter to program the advanced features of the Model XMT868i’s Keypad Program.

The Keypad Program provides access to the various programmable features of the Model XMT868i. Step-by-step programming instructions are presented in this chapter. Refer to the appropriate section for a discussion of the following menu features:

•Channel-ACTIV — activate one or both channels and select the desired measurement method

•Channel-SYSTM — enter the individual channel parameters

•Channel-PIPE — enter the pipe parameters

•Channel-I/O — set up the inputs and outputs

•Channel-SET UP — set the signal limits, response times and activating mass flow.

•GLOBL-SYSTM — enter the system units

•GLOBL-I/O — set up error handling, option cards and display

•GLOBL-COMM — set the serial port and MODBUS parameters

As a programming aid, a complete set of menu maps for the PROG menu is included in Appendix A, Menu Maps. The specific figure numbers will be referenced throughout this chapter, as required.

1.2Programming Methods

You can use two methods for programming the XMT868i flowmeter:

•The keypad (shown in Figure 1 on page 2), which permits direct communication with the XMT868i

IMPORTANT: The XMT868i’s keypad permits programming of the instrument through the glass faceplate without removing the cover. Thus, all programming procedures may be performed while the unit is installed in a hazardous area.

•PanaView™, a PC-based software program that communicates with the XMT868i using its RS232/RS485 serial Ethernet port.

Although the displays differ, the general procedures are the same for the keypad and PanaView methods. This chapter provides detailed keypad programming instructions. If you are using PanaView, please refer to Appendix C,

Programming with PanaView, and/or the PanaView User’s Manual for complete instructions.

Chapter 1. Programming Site Data

Keypad Program

Along with the 2-line, 16-character LCD, the XMT868i includes a 6-key magnetic keypad. The decal cutout for each key contains a hall effect sensor, pushbutton switch and visible red LED. The magnetic wand used to activate a magnetic key is found attached to the meter chassis below the front panel. An operator activates the key by pressing the magnetic wand up to the glass lid over the desired key. The LED will light indicating a successful key press.

Note: The pushbutton switch will also act as a key press but is done with the glass lid open. Do not use the pushbutton switch in a hazardous area where the lid needs to be installed.

Use the magnetic keypad to navigate through the user program. The menu map may be followed in sequence, or the four arrow keys may be used to scroll through the prompt screens. Figure 1 shows the front of the XMT868i, with magnetic keypad and magnetic wand.

Magnetic Wand

Figure 1: XMT868i Magnetic Keypad and Wand

Programming of the ACTIV, SYSTM, and PIPE submenus of the CHx menus and the GLOBL-SYSTM menu are required for basic operation of the Model XMT868i. Failure to accurately enter all of the necessary information will result in unreliable flow data. Therefore, be sure to complete at least the sections of this chapter pertaining to those three submenus.

Note: Because it is so essential, instructions for programming the ACTIV, SYSTM, and PIPE submenus of the CHx menus and the GLOBL-SYSTM submenus are also included in the Startup Guide. If that programming has already been completed, skip those sections in this chapter.

Except for the three submenus noted above, it is not necessary to program the Model XMT868i flowmeter in any particular order. Therefore, the sections of this chapter need not be completed in sequence. Enter the keypad program as described in Accessing the Keypad Program on the next page and proceed immediately to any section of interest.

Note: Be sure to record all the programming data entered in this chapter in Appendix B, Data Records.

1.4.3 Entering Communications Data

The Model XMT868i flowmeter is equipped with an RS232 or an RS485 serial interface. MODBUS (RS485), MODBUS/TCP, Ethernet and Foundation-Bus options are available. When the MODBUS, MODBUS/TCP or Foundation Field Bus options are present, the XMT868i may also have the standard RS232/RS485 serial interface. When the Ethernet option is present, the RS232/RS485 serial interface is not present.

Note: To set Fieldbus communications parameters, see Appendix E, Foundation Fieldbus Communications.

The serial port is used to transmit stored data and displayed readings to a personal computer by connecting the meter’s serial interface to the serial port of the PC. In addition, the Model XMT868i can receive and execute remote commands, using PanaView software, using this link.

Use the COMM option to set the communications port and MODBUS parameters. While following the programming instructions, refer to Figure 31 on page 80.

1.4.3a Setting Up the Serial Port

1.To enter this submenu from the Global PROGRAM menu, scroll to COMM and press [Enter].

2.Enter a Meter Address number between 1 and 254 and press [Enter]. The default number is 1.

A meter address is only necessary for communication with the GE PanaView software. See the PanaView User’s Manual for more information.

IMPORTANT: If the meter address or baud rate is changed, communication with PanaView must be re-established with the new address number.

3. Scroll to the desired Baud Rate (300 to 19,200) and press [Enter].

IMPORTANT: The Ethernet option requires that the meter’s baud rate is set to the same rate as the Ethernet option. The factory default is 9600 baud. If a different baud rate is desired, first change the meter’s rate, and then change the Ethernet’s baud rate setting by using the Device Discovery utility.

•If you have the RS485 MODBUS option, proceed to step 4 on the next page.

•If you have the standard RS232 serial interface or optional Ethernet interface, the meter exits the COMM submenu and returns to the Global PROGRAM prompt.

1.4.3b Setting Up MODBUS (RS485) and MODBUS/TCP Communications

When equipped with an optional MODBUS output card, the XMT868i can transmit flow data serially to a flow computer, or SCADA, using a Gould-type RTU protocol. Thus only the MODBUS function command, 3 (read multiple registers), 6 (write multiple registers) is valid. The XMT868i uses the following format for the data exchange:

•The Send command (initiated by the host flow computer or controller) comes in the form: [time delimiter]<Addr><3><First Register MSB>

<First Register LSB> <Register Count MSB>

<Register Count LSB><CRC Low><CRC High>[time delimiter]

•The Response (initiated by the host flow computer or controller) comes in the form: [time delimiter]<Addr><3><Byte count><Data………..>

<CRC Low><CRC High>[time delimiter]

The format for the returned data types is:

•Integer (16 bit Integer) <MSB><LSB>

1Register — 16 bit integer

•Integer (32 bit IntegerI) <MSB><LSB><LSB><LSB>

2Register — 32 bit integer

•Floating Point (FP)<EXP><MAN><MAN><MAN>

2Registers — 32 bit IEEE floating point number

Use the steps below to configure MODBUS communications:

IMPORTANT: The XMT868i MODBUS communications settings chosen in the next four steps must match those of the MODBUS control system.

4. Scroll to the desired MODBUS Baud Rate and press [Enter].

IMPORTANT: The MODBUS./TCP interface requires a baud rate of 9600.

5.Scroll to the MODBUS Parity and press [Enter].

6.Scroll to the MODBUS Stop Bits and press [Enter].

7.Enter a MODBUS Meter Address (between 1 and 254) and press [Enter]. (The default address is 1.)

The meter returns to the Global PROGRAM prompt. Press [Escape] twice to return to the Keypad Program, and a third time to return to the meter display.

IMPORTANT: You must reboot the XMT868i to load the new settings.

Refer to the section Requesting Parameters Using MODBUS on page 40 to retrieve data from the XMT868i using MODBUS.

1.4.3c Setting Up a MODBUS/TCP Connection

A modified XMT868i can use the MODBUS/TCP interface to communicate with an internal network. An optional MODBUS/TCP card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector. To connect the MODBUS/TCP-enabled XMT868i to the network, insert the jack of an RJ45 cable into the RJ45 connector, route the cable through a conduit hole with an appropriate cable clamp, and wire the other end of the cable to the LAN according to the manufacturer’s instructions.

To establish MODBUS/TCP communications with the XMT868i, you must install the Ruiping software utility (available with your modified XMT868i) on a PC connected to the LAN. Once installed and running, the software displays all Ethernet devices currently connected to the subnet. You can identify the XMT868i by its MAC address, supplied as part of customer documentation. The default TCP Port is 502.

The default IP addressing for the XMT868i is DHCP (dynamic). If you need to assign a static IP address to the XMT868i, complete the following steps:

IMPORTANT: To assign a static IP address, the XMT868i must be connected to an Ethernet network with a dynamic address assignment mechanism (DHCP) first.

1. Run Ruiping software, and identify the XMT868i’s current IP address.

Note: “Ruiping-e” will return the found IP addresses as well as the MAC address.

2.From a DOS command prompt, type: telnet “ip address” 10000

3.The “Welcome to Net+Works Configuration Utility” opens. Type in the login name and password.

a.Login: type root.

b.Password: type Netsilicon.

4.In the Main Menu:

a.Select IP Parameters (1). Enter the desired IP changes and return to the Main Menu.

b.Select Enable DHCP Client (3). Select N (2) to disable, then select 4 for Main Menu.

c.At the Main Menu, select 4 for Quit. Power cycle the XMT868i (i.e., turn the meter off and on) to apply the changes.

Refer to the section Requesting Parameters Using MODBUS on page 40 to retrieve data from the XMT868i using MODBUS.
