Example 1 Local CPU as Master (Client)
The CPU is to work as a Master (Client) using standard
Modbus/TCP to read one coil (Count) from the Slave
(Server) at address register 0 and write the value to the
CPUs first output coil, Q1.
Remote 1 is the channel that belongs to the Slave and its
IP address (192.168.0.227) and port number (5001) is
configured using Tools  Transfer  Web Server Config:
