  baxtersherriSep 5, 2025
  If you cannot communicate with the Siemens Controller, verify that all communication settings match those used by ReyDisp Evolution. Also, check that the Tx and Rx fibre-optic cables are correctly connected (Tx to Rx and Rx to Tx). Confirm that all cables, modems, and fibre-optic cables are working correctly. Make sure that IEC 60870-5-103 is specified for the connected port (COM1, COM2, COM3, or COM4).
