(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.
Additional Communications Response Delay is used to synchronize Modbus communications with hosts that
operate at a slower speed than the device. The value specified here will be added to each response the
device sends to the host.
Default: 0
Range: 0 to 255
TIP
Do not set Additional Communications Response Delay unless required by your Modbus host.
