I have MOXA modbus gateway (modbus RTU to Modbus TCP) which connects power meter in series using RS-485 all the meter have same Serial port setting with different ID's. Modbus tcp has a unique ip address and TCP port:502. With every other software like KEPSware and MODSCAN all the devices communicate and gives data with same configuration except slave id. So there is no problem in commuincation. But in SICAM PAS when i create a modbus Master interface and add two devices only one communicate while other show connection error and when i stop the working one and start the other one the previous working one shows communication error. Also if the create a new interface and add the non working device, it start communicating. SO MY QUESTION IS DO i have to create new interface for each device connected on the gateway or is there any other solution b/c i have almost 90 devices on 6 gateways?? NOTE: i am using trial version of SICAM PAS for now to test my hardware. Also all the above stated devices show proper data on SICAM PAS if confiqured seperately so issue on address or any other things ------------------------------------------------------------------------------------------ |
