Function and input

The M function is split into the specified M

The currently active M function can be split into

the two specified M functions. You can cancel it in

part by canceling one of the specified M

functions. The currently active M function is split

up if part of it is canceled by the MP_revoke

Example: M13 = Spindle ON clockwise (M3) +

coolant ON (M8)

If function M13 is active and an M5 is collected

during the block scan, for example, the function

M3 contained in M13 is canceled. Only function

M8 remains active. In this case, enter 3 and 8 in

the parameter.

List [2] with numerical values

Numbers of M functions

After the block scan, the collected M functions are

implemented in the order of their group IDs

(starting from the lowest).

Numerical value

0 to 2147483647

Automatic tracking of the active M functions

Normally the PLC program has to use the module

9088 to track the status of the active M function.

Set this parameter to TRUE if the PLC run-time

system is to implement the status automatically.

Selection menu

The status of the active M function is tracked

automatically, depending on the

MP_trackMState parameter (CfgPlcOptions).

The status of the active M function must be

tracked by calling Module 9088.
