Signals from/to the MCP

Horizontal MCP with override switches
The figure below takes the horizontal MCP variant with override switches as an example. The vertical MCP variants share
the same PLC interface addresses for the corresponding keys.
Note that labels K13, K15, K19, and K21 are not included in the pre-inserted labeling strips for keys of the MCP. The figure
includes these labels so that when you read the information in the following two tables, you know which keys on the MCP it
refers to.
