Flexible Interface Module Example
In this example, a PLC-5/15 is used to send a message through a Flexible
Interface Module (Catalog No. 2760-RB) using RS-422 communications.
The RS-422 communications port is compatible with the DL50 RS-485 port.
Figure 6.2 illustrates the setup. The Simulator Module (Catalog No.
1771-SM) provides the external inputs, in your application this may be any
of a variety of I/O modules.
