How to troubleshoot communication issues with a Siemens 7SR224 Controller?
If you cannot communicate with the Siemens Controller, verify that all communication settings match those used by ReyDisp Evolution. Also, ensure the Tx and Rx fibre-optic cables are connected correctly (Tx –> Rx and Rx –> Tx). Check that all cables, modems, and fibre-optic cables are functioning correctly and that IEC 60870-5-103 is specified for the connected port (COM1, COM2, COM3, or COM4).
Why Siemens 7SR224 relays will not communicate in a ring network?
If the Siemens Controller relays will not communicate in a ring network, check the following: * Ensure that the Data Echo setting on all relays is set to ON. * Verify that all relays are powered up. * Confirm that all relays have unique addresses.
What to do if status inputs do not work on a Siemens Controller?
If the status inputs on your Siemens Controller are not working, check that the correct DC voltage is applied with the correct polarity. Also, verify that the status input settings, like the pick-up and drop-off timers and the status inversion function, are correctly configured.
