Chapter 4: PLC Communications

Typical Communication Applications

The diagrams on the following four pages illustrate the typical uses for the CLICK PLC's
communication ports. Typical serial communication applications are continued on the next
three pages.
Port 1 (RS-232) – Modbus RTU Slave Mode Only
Basic, Standard and
Analog PLCs
TIP: C-more Micro-Graphic panels
(monochrome models only) can get 5 VDC
power from RS-232 Port.
Example
Port 1 or 2
RS-232 Port
NOTE: CLICK's RS-232 port can provide 5VDC to power one monochrome Micro-Graphic panel. If
two C-more Micro-Graphic panels are connected to both ports, then at least one of the panels must be
powered by a C-more Micro DC power adapter, EA-MG-P1 or EA-MG-SP1, or another 24VDC power
source. Color C-more Micro-Graphic panels must also be powered from a separate 24VDC source.
