The enabler updates the diagnostic points and communicates with the highest-ranking PLC.
The enabler continues to monitor the mode bits at the configured heartbeat timer interval.
Review a list of Series 90 TCP/IP Redundancy failure conditions and actions.
The Series 90 Diagnostic Program is a program provided with the Series 90 Triplex Communications enabler that you can use to check the basic operation and configuration of your network without starting CIMPLICITY software.
Note: It does not validate redundant PLC behavior, only basic connectivity and read & write capabilities.
You can perform the following functions:
Live update of the currently displayed domain
Read load test
Write load test
For this program to function, CIMPLICITY software's Series 90 Triplex Communications enabler must be successfully installed, and you must have configured the Triplex port and Series 90 devices using CIMPLICITY application configuration functions.
To start the diagnostic program, click the Series 90 Diagnostic icon in the CIMPLICITY Workbench.
The SRTPDiag window opens.
To connect to a Series 90 programmable controller in the TCP/IP network:
Click on the drop-down list button to the right of the Device field to display the list of currently configured devices, and select a Series 90 device from the list.
Click on the drop-down list button to the right of the Port field to display the list of currently configured ports, and select the TCP/IP port to use.
Click on the drop-down list button to the right of the Domain field to display the list of currently supported domains (memory types ), and select a domain to display.
The program makes the connection with the programmable controller, and displays the values contained in the requested domain.
To display the data for another domain, just select the domain from the drop-down list in the Domain field. The data for the new domain is automatically read and displayed in the data box.
You can use the menus and buttons to do the following:
Toggle between manual and automatic data update modes.
Request manual reads of domain data
Request writes to the programmable controller
Display programmable controller status
Perform a read load test
Perform a write load test
