Dear sir, i am using s7 1200 CPU 1215C DC/DC/DC and CM1214 RS 422/485 conversion module TIA Portal version 15 i am trying to communicate delta energy meter via modbus RTU communication. i am unable to read multiple holding register and able to read only one register at a time in modbus master communication block. when i am increase the data length into the modbus but still he will give the only one holding register value aslo i am increase the data length above 30 the i got error (Error code is 16#8382) is any other way to read multiple holding resister. also i give 4 communication block each block for separate modbus address but the value of the resister is't received as the original value of the multi function meter the value is continuously vary. waiting for your valuable replay. regards, Dada@1
