Hi,

Have you ever activated the Integrated resistors (pull-up, pull-down)?

Please see below picture:

Also 700DHEX means reading register error? May it be caused to read unaccessible register address? Could you please share with us your reding address, baud rates and other modbus settings(both plc and driver side)?
