Miscellaneous:	The Allen-Bradley 1756-L55M23 controller can be inserted into any slot of a chassis and multiple controllers can be installed in the same chassis. Multiple controllers in the same chassis communicate with each other across the backplane but operate independently. The 1756-L55M23 Controllers can communicate across RS-232-C (DF1/DH-485 protocol), DeviceNet, DH+, ControlNet, and EtherNet/IP networks. To provide communication for a 1756L55M23 Controller, an appropriate communication module must be installed.
