It looks like you use panel as master and engine as slave.

Master named ID1   and  you try to read data from slave ID1 --- it is not correct.

Please change this nodes to different ID and try to read needed data.

You can change ID on engine to 2 or if it imposible - change master PLC ID to another one.

Please post your modbus setup. Motor and drive nameplate and how modbus wires is connected to V700.  Sometimes A & B RS485 wire is swaped.

If you use USB connection to V700 - com port 1 is not work with modbus - it is connected to USB and Visilogic.

If it possible please use PC Modbus software and USB to R485 connection for test drive communication.

Please note - In drive parameter - you must configure communication settings drive ID  and enable Modbus communication.
