• Page 14: Command Format

  Each command entry must be concluded by a delimiter. This can either be a line feed (LF) or a semi‐colon (;). If an end label is all that is sent to the WE2107, the WE2107 input buffer is cleared. The data provided in round brackets () for the commands are mandatory and must be entered.

• Page 15: Responses To Commands

  WE2107 — Communication commands Responses to commands NOTE Note on the reaction times of the WE: The reaction times specified for the WE in the command description do not include the time taken to transfer the command to the WE and the time taken to transfer the response from the WE.

• Page 16: Responses To Parameter Queries

  WE2107 — Communication commands 2.3.2 Responses to parameter queries A parameter query is entered by using the command with a question mark attached. A parameter query is always answered in ASCII format. The end label is a line feed (LF = 0A hex).

• Page 17: Output Types For Measured Values

  WE2107 — Communication commands Output types for measured values The response to measurement queries (MSV?) depends on the output format (COF) that is set (binary or ASCII output). Data output works with fixed output lengths (see command COF): Example: Format command WE2107 response No.

• Page 139: Communication Examples

  WE2107 — Communication commands Communication examples Making settings for bus mode The WE is able to work with up to 32 modules in a bus. The prerequisite for this is that each WE is connected to the bus by an RS‐485 interface driver. Each WE operates as a slave, that is to say, without being prompted by the bus master (e.g.

• Page 140: Setting The Data Output

  WE2107 — Communication commands Setting the data output For data output using the command MSV?; the output format must previously have been set in all the modules. To do this, proceed as follows: 1. Enter the broadcast command ;S98; All the WEs execute the command, but do not send a response.

• Page 141: Setting The Baud Rate

  WE2107 — Communication commands Setting the baud rate The WE can work at different baud rates. The setting can only be changed via the serial interface by using the command. Of course in bus mode, the baud rate of all the connected users must be the same. To make sure that the WEs in a bus are always safely set to the required baud rate on initialization (power‐up) of the hardware (in this example 9600 = BR0), proceed as follows:…

• Page 142
  WE2107 — Communication commands NOTE It is essential to output the semicolon before the command S98;, as controlling the WE at different baud rates may result in undefined characters in the WE input buffer. These characters are rejected when the semicolon is received.

• Page 143: Determining Bus Occupation (Bus Scan)

  WE2107 — Communication commands Determining bus occupation (Bus Scan) It is often useful, each time the bus is enabled or if WE responses are missing, to determine the bus configuration. Use Bus Scan to determine bus address occupation. The prerequisite here is for all the modules to be set to the same baud rate.
