Actions in synchronized actions

2.7.1

Output of M, S and H auxiliary functions to the PLC

Output timing
Auxiliary functions of the M, S and H type can be output from synchronized actions. The
output to the PLC is immediate, i.e. directly in the interpolation cycle in which the action is
executed.
Any output times set via the machine data for auxiliary functions have no effect when output
from synchronized actions:
● MD11110 $MN_AUXFU_GROUP_SPEC (auxiliary function group specification)
● MD22200 $MC_AUXFU_M_SYNC_TYPE (output time of M functions)
● MD22210 $MC_AUXFU_S_SYNC_TYPE (output time of the S functions)
● MD22230 $MC_AUXFU_H_SYNC_TYPE (output time of the H functions)
Maximum number
General
A maximum of 10 auxiliary functions can be output simultaneously from the part program
and the active synchronized actions of a channel, i.e. in one OB40 cycle of the PLC.
Synchronized-action-specific
The maximum permissible number of auxiliary functions in the action part of a synchronized
action is:
● M functions: 5
● S functions 3
● H functions: 3
Non-modal synchronized actions
In non-modal synchronized actions (without specification of
