Issue writing to External Modbus Slave using Write_Var

[jpresco1]

I am trying to write to a register, 572 and 573 in this case, to an external motor using modbus TCP. I am able to read the register value of 572 and 573 using the read_var fbd but am unable to write anything to it using the write_var. The motor designates 2 addresses for each parameter so I am writing 2 INT Array starting at 572 to write 0,0 but the motor does not write the to the parameter when running the plc. When monitoring the GEST for the Write_VAR, the first word will give an exchange number but then the number won't change like expected (it constantly is updating within the read_var fbd). Is there something I am doing wrong within the ADDM addressing of '0.0.3{192.168.10.10}TCP.MBS'? 192.168.10.10 is the IP of the external unit.

Check the status of operation and communication report bytes (GEST byte #2). Also, don't forget to set a timeout in GEST byte#3.

Check the triggering of the write operation.  I assume you are using the ethernet port of the CPU (0.0.3) to read and write.  Does the motor require a UNit ID that is not 255?  If in the DTM you can try to manually configure a read or writer operation, to test the operation before coding it.
