Dear Parshva, Thanks for message, we are using pin 3 TxD+ and pin 8 TxD- for RS485 connection SHELL chasis ground terminal not available at Slave side. Can we use the simple DB9 connector at CM1241 side or is it compulsory to use the dedicated Profibus-DP connector..?? We are using ModbusPoll with ADAM-4561 interface for the testing of Modbus Master CM1241 but LED's not responding. Thanks. |
