Introduction (cont’d)
The panel can also be connected to more than one PLC by using RS-422 or RS-485 wired in
a multi-drop configuration. Port1 and Port2 cannot simultaneously communicate with
multiple PLC’s. See the example wiring diagrams at the end of this chapter for details.
If you have difficulty determining whether the particular PLC and/or protocol you are using
will work with C-more Micro-Graphic panels, please contact our technical support group at
