PLC Function Keys

and Controls
In BTVs with integrated PLC, the machine function keys are directly connected
to the PLC and therefore they can be directly addressed by the PLC program.

Fig.4-8: Addressing of machine function keys
Instead of the direct address entry also address constants for Bosch Rexroth
firmware data types can be used.

Fig.4-9: Addressing with address constants
The MFK_L data type contains the L1, L2,..., L8 elements of the BOOL type.
The MFK_R data type contains the R1, R2,..., R8 elements of the BOOL type.
Example in the PLC program: MFT_L.L1
