NC/PLC Interface Signals (Z1)
2-76 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
DB21, ...
DBB68 - DBB97
M functions 1 to 5
Extended address M functions 1 to 5
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.
DB21, ...
DBB98 - DBB115
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

Edge evaluation: no Signal(s) updated: Job-controlled by NCK
Signal state 1 or
edge change
0 → 1
The T function programmed in an NC block is made available here
as soon as the T change signal is available.
Value range of T functions: 0 to 99 999 999; integer number
The T function remains valid until it is overwritten by a new T function.
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)
Control of automatic tool selection.
Special cases,
