Good afternoon. there is a PLC Quantum CPU 113 03 to which a frequency Converter is connected (modbus plus Protocol).below is a photo of the data exchange algorithm.the essence of the problem is as follows.if register 000111 is set to true, the frequency Converter is read from the address 2011 (on the frequency Converter) corresponding to the address of register PLC 401100, the readings are correct. But when you try to write to the Frequency Converter value does not come. the recording is done by assigning the register value 000211 "true" and assigning the value to the PLC register No. 401120, which corresponds to the register 2001 of the frequency Converter. Please tell me what I'm doing wrong? The algorithm works fine, just change the rendering environment. I hope you can help me.
