M, S, T, D, H, F functions Additional info "Quick" (fast acknowledgment)
Edge evaluation: No
Signal(s) updated: job-controlled by NCK
Signal state 1 or
edge change
0 → 1
One M, S, T, An D, H, or F function has been output to the interface with a new value together with
the associated change signal at the beginning of an OB1 cycle.
In this case, the additional info "Quick" indicates the quick help function.
Signal state 0 or
edge change
1 → 0
The change signals are reset by the PLC basic program at the start of the next OB1 cycle.
The value of the data involved is not valid.

M functions 1 to 5
Extended address M functions 1 to 5
Edge evaluation: No
Signal(s) updated: job-controlled by NCK
Signal state 1 or
edge change
0 → 1
Up to 5 M functions programmed in an NC block are simultaneously made available here as soon as
the M change signals are available.
Value range of M functions: 0 to 9999 9999; integer number
Value range of the extended address: 0 to 99; integer number
The M functions remain valid until they are overwritten by new M functions.
Signal state 0 or
edge change
1 → 0
• After the PLC has ramped-up.
• All help functions are deleted before a new function is entered.
Application
example(s)
Decoding and evaluation of M functions that are not decoded as standard or via a list.
Using the extended address, the M function can be assigned to another channel that does not
correspond to that channel in which the program is running.
Special cases,
errors, ......
For
M00
to
M99
the extended address = 0.

S functions 1 to 3
Extended address S functions 1 to 3
Edge evaluation: No
Signal(s) updated: job-controlled by NCK
Signal state 1 or
edge change
0 → 1
Up to 3 S functions programmed in an NC block are simultaneously made available here as soon as
the S change signals are available.
Value range of the spindle speed: 0 to 999 999; integer number
Value range of the extended address: 0 to 6; integer number
The S functions remain valid until they are overwritten by new S functions.
Signal state 0 or
edge change
1 → 0
• After the PLC has ramped-up.
• All help functions are deleted before a new function is entered.
Application
example(s)
Spindle speed control by the PLC.
The extended address is used to program for which spindle the S word is valid.
E.g.: S2=500
