Q
I'm trying to read/write the values of the Micromotion transmitter 1700 via Modbus RTU protocol by Siemens S7 314 with CP341-1(RS485). Up to now, I can read/write the values of input/holding register type with function code
3,4,6,16. But I can not read/write the values of floating point register pairs. It always alarmed "illegal data address". Would someone like to tell me how to make the program read/write the float point value of transmiter 1700? And is there any parameters should be set to
the transmitter before writing values to it?
