Hi
Can you please guide me to understand how to establish communication between a Merlin Green S10MD power meter (Sepam 40) and a Citect SCADA system.
I have these modules:
Merlin Gerin power meter: S10 MD (Sepam 40)
Network Interface: ACE949-2 (2-wire RS485)
Merlin Gerin Gateway: EGX100MG (Modbus Serial to Ethernet Gateway)
I made the connection as follows:
From the power meter to the network interface (RJ 45) and from there to EGX100MG through Modbus serial RS485-2 wire connection.
I assigned IP Address to the gateway, and I have connection to the gateway through web browser and try to read power meter registers through gateway. I tried every Baud Rates (4800, 9600, 19200, 38400) and Every possible parity (Even, None) to connect to the power meter (S10 MD, Sepam 40). But still I have problem in reading data through EGX100MG Serial RS485-2 wire. The LED on the network interface (ACE949-2) is On and green (not flashing), and in EGX100MG gateway, the RS485 LED is On but the TX and RX LEDs (RS485 side) are off all the time. all commands to the available Modbus node (power meter) are failed with time out error. Do you have any suggestion to help me to connect power meter to gateway?
