(Optional) Set Additional Communications Response Delay in "delay units."
A delay unit is 2/3 of the time required to transmit one character, as calculated for
the port currently in use and the character transmission parameters. Valid values
range from 1 to 255.
Additional Communications Response Delay is used to synchronize Modbus
communications with hosts that operate at a slower speed than the transmitter. The
value specified here will be added to each response the transmitter sends to the
host.
Tip
Do not set Additional Communications Response Delay unless required by your Modbus host.
