If you have CHARM I/O Blocks
you need the system to communicate with, you can install a CHARM I/O Gateway on
the DIN rail anywhere you would install a CHARM Baseplate.
Figure: Installing a CHARM I/O Gateway
In this example, the CHARM I/O
Gateway is installed directly beneath the CIOC Carrier.
Hold the CHARM I/O Gateway beneath the CHARM Baseplate installed
on the DIN rail and notice how the connectors on the top of the CHARM I/O
Gateway interlock with the connectors on the bottom of the baseplate.
Align and fit the connectors together as you snap the CHARM I/O
Gateway onto the DIN rail.
A latch on the back of the CHARM I/O Gateway snaps it into
place on the DIN rail.
