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.
