FC24: MCP_IFM2 - transferring MCP signals to the interface

Function
The block FC24 (MCP_IFM2, M variant, e.g. MCP 310) is used for transferring data from the
machine control panel to the NC/PLC interface:
● Modes
● Axis selections
● WCS/MCS switchover
● Traversing keys
● Overrides or override simulation signals
● Key-operated switch position
The following specifications apply to the feed override, axis travel keys and INC keys
depending on the active mode or on the coordinate system selected:
● Feed override:
– The feed override is transferred to the interface of the selected channel and to the
– The feed override signals are transferred to the NC channel in addition to the "Rapid
● Machine functions for INC and axis travel keys:
– When the MCS is selected, the signals are transferred to the interface of the selected
– When the WCS is selected, the signals are transferred to the geometry axis interface
– When the system is switched between MCS and WCS, the active axes are generally
The associated LEDs on the machine control panel are derived from the acknowledgements
from the relevant selections.
