COM-05 Resp Delay: the 485 communication(Modbus-RTU or LS INV 485) built in iS7 acts as a slave. The slave
iS7 responds to the Master after the period of time set in this function code. The communication between the master
and slave can be kept smooth by setting this function code properly in a system in which the master is not able to
deal with the quick response of the slave.
