The Modbus Client Scan rate is set to
1000msec and each mapping is
configured with a response timeout (in
this case 1000msec). This time is how
long the master will wait for a response before indicating the failure on the Comms Fail

*Note: The IP address 127.0.0.1 is a standard loopback address that represents
“localhost” (this computer). Using the loopback address will mean if the module
address is ever changed the Server IP address will not need to be changed as it
will automatically use the localhost address.
