Modbus instruction handling mode has changed in XD/XL series PLC, users can write
Modbus instructions directly in program, the protocol station will queue up Modbus requests,
which is not the same task with communication; It means users can use one triggering
condition to trigger multiple Modbus instructions at the same time. PLC will queue up
Modbus requests according to protocol station, which will lead to communication error in XC
series PLC.
