Mode bits: Multiple Masters
About this task
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.
