User Communication System
The OpenNet Controller CPU module has two RS232C ports and one RS485 port to control two RS232C devices and one
RS485 device such as IDEC’s HG series operator interface at the same time.
The figure below illustrates a system setup of remote I/O and user communication. In this example, the I/O statuses of a
remote machine are transferred through the remote I/O line to the CPU. The data received through modems is monitored
on a computer and also sent to a pager transmitter.
For details about the remote I/O system, see page 24-1.
For details about the modem mode, see page 23-1.
