To Configure the S7-200 PPI PLC to communicate with the C-more Panel, you will first need to find the Port Settings for your Siemens PLC.

  1. Open the Step 7-Micro/WIN Software and select the System Block icon on the left side panel of the Step 7 Software as shown below.
  • This will open the System Block window, which is also shown below.

With the System Block window open to use as reference, continue to the C-more Programming Software to Configure the Panel Manager as discussed below.

  • from the Navigation window, click the Function tab, click Setup and then select Protocol Manager.

  1. From the Protocol Manager window, click the Device name on the tree to the left.
  • The Device Setup window opens.
  1. From the PLC Protocol field, click on the down arrow and select Siemens S7-200 (Serial : PPI).

Use the Step 7-Micro/WIN Software screen on the top of this page as reference. Configure the Panel Manager as follows:

  1. PLC Slave Number: This is the PLC Address of the PLC Port to which that the C-more Panel connects.

 

Note: In the Step7 MicroWin Software, the settings for the Ports are displayed from left to right, meaning that Port 0 is on the left and Port 1 is on the right, as shown on the Step 7 graphic on the top of this page. However, on the physical PLC itself, Port 1 is on the left and Port 0 is on the right.
  1. Baud Rate: This setting should match the Baud Rate set in the System Block screen for the appropriate Port. The choices are 9600 or 19200.
  2. Parity, Stop Bit, Data Bit and Select RS485: These items are not adjustable from this window and are display only.
  3. Retries: This is the number of times that the Panel will Retry to send a Message if the request does not receive a Reply in the specified Timeout period. Once the Retry count has been reached, the Panel will show an Error on the screen and begin trying to send messages again.
  4. Timeout Time: This is the amount of Time (in 100 milliseconds) that the Panel will wait on a Reply after sending a request. Once the Timeout Timer expires, it will then Retry.
  5. Poll Time: This is the amount of Time (in milliseconds) that the Panel will wait in between each request.
