Добрый день. имеется плк Quantum CPU 113 03 к которому подключен (протокол modbus plus) частотный преобразователь .ниже прикреплена фотография алгоритма обмена данными.суть проблемы в следующем.при присвоение регистру 000111 значения “true”происходит считывание с частотного преобразователя с адреса 2011(на частотном преобразователе)соответствует адресу регистра 401100 плк ,считывание проходит корректно значения отображаются. Но при попытки записи на частотный преобразователь значение не приходят. запись происходит путем присвоения регистру 000211 значения “true” и присвоение значения регистру плк номер 401120 который соответствует регистру 2001 частотного преобразователя. Подскажите пожалуйста что я делаю не так? Алгоритм точно рабочий, просто меняем среду визуализации. Надеюсь на вашу помощь. (oo) (oo) (oo) (oo) (oo)

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. (oo) (oo) (oo) (oo) (oo)

just try with 1 offset address in quantam read write block
means if you want to write 40121 then try with 40122

Thanks for your help. But I already knew what was going on. as it turned out, the PLC stands as a reserve touch panel.and all registers are written by the panel using the TSXCUSBMBP Converter.
