Hi,

I want to ready V2900.0 etc memory address from the EM277. I am using hilscher profibus to modbus gateway. All communication digagonostics are okay, but i cannot read any value.

Please specify what registers i have to use as in/out. Currently i am using 16 words out/16 words in.

Your quick response will be highly appreciated.

I am facing problem while configuring the NT 100 RE EP Hilscher Gateay.

I have Siemens S7-200 PLC connected to EM277 for data transfer. I want to acquire the V memory address V2900.0, V2900.1 etc from EM 277. I configured the X2 port as Open Modbus and X3 port as Profibus master on the NT 100 RE DP module

I selected 64 bytes out/64 bytes in for EM277 in the Hilscher Gateway.

As for as the Hilscher Gateway hardware is concerned. I can observe with the diagnostics that hardware is communicating but i cannot read any value in the Diagonostics IO Monitor.
