Assignment Of An Auxiliary Function To A Number Of Groups - Siemens SINUMERIK 840D sl Function Manual

H2: Auxiliary function outputs to PLC
8.13 Behavior during block search
In this case, the spindle-specific auxiliary functions M3, M4, and M5 are not suitable because
they might not be output to the PLC until after the spindle positioning.
For detailed information on the block search, see Section "K1: Mode group, channel, program
operation, reset response (Page 455)".
8.13.2

Assignment of an auxiliary function to a number of groups

Function
User-defined auxiliary functions can also be assigned to multiple groups via the group
assignment (MD22000 $MC_AUXFU_ASSIGN_GROUP). During the block search these
auxiliary functions are collected for all the configured groups.
Note
Predefined auxiliary functions can only be assigned to one group.
Example
The DIN includes the following M-commands for coolant output:
● M7: Coolant 2 ON
● M8: Coolant 1 ON
● M9: Coolants 1 and 2 OFF
Consequently, both coolants can also be active together:
● If M7 and M8 are collected in two separate groups (e.g. groups 5 and 6)
● If M9 has to be assigned to these two groups, e.g.
– Group 5: M7, M9
– Group 6: M8, M9
Parameterization:
MD11100 $MN_AUXFU_MAXNUM_GROUP_ASSIGN = 4
MD22000 $MC_AUXFU_ASSIGN_GROUP [0] = 5
MD22000 $MC_AUXFU_ASSIGN_GROUP [1] = 5
MD22000 $MC_AUXFU_ASSIGN_GROUP [2] = 6
MD22000 $MC_AUXFU_ASSIGN_GROUP [3] = 6
MD22010 $MC_AUXFU_ASSIGN_TYPE [0] = M
MD22010 $MC_AUXFU_ASSIGN_TYPE [1] = M
MD22010 $MC_AUXFU_ASSIGN_TYPE [2] = M
MD22010 $MC_AUXFU_ASSIGN_TYPE [3] = M
