(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
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.
