Dear expert, I plan to connect the power meter with Modbus RTU (brand: Mun Hean, model:MD-VAFR+) via a N-port device to WinCC without OPC. So my question is whether WinCC is able to communicate with this power meter to read the power meter reading. Power meter specification: RS485 Modbus RTU protocol Baud rate: 9600 bps Data bit: 8 parity - none stop bit: 1 Date Type: holding resister Data Form: Float E.g for CT Ratio 5/5A assuming meter reading: EB: 00020000 Note: 32 bit float in 2 registers. Kindly refer to the attached drawing for the network topology. Thanks and regards, Tan
