AutomationDirect Controllers
AutomationDirect Productivity Series PAC, CLICK, SOLO Temperature Controller and
GS Drives
Drivers specific to these AutomationDirect control devices make it convienient to communicate
with the
C-more
Micro-Graphic panels and simplify configuring objects with controller
addresses.
RS-422A/RS-485A Communications
When using the RS-422A/RS-485A communications capabilities of the
C-more
Micro-Graphic
Serial Port (Port 2), the termination resistor is placed between the
RXD–
and
RXD+
terminals
on the PLC side of the connection between the touch panel and PLC. The Termination Resistor
value is based on the characteristic impedance of the cable being used. To enable the built-in
120 Ohm Termination Resistor, jumper pin
13
(termination resistor) to pin
9
(
RXD+
) on the
C-more
15-pin PLC communications port.
Allen-Bradley
As stated in this chapter’s introduction, the panel also has the ability to communicate with
Allen-Bradley PLCs that support the Allen-Bradley DF1 and DH485 protocols. The chart for
the various Allen-Bradley PLCs includes recommended cables.
GE, Mitsubishi, Omron, Modicon and Siemens
Other 3rd party PLCs can be used with the
C-more
Micro-Graphic panel. These PLCs are listed
in a chart and various wiring diagrams are shown to allow connectivity.
