M function Change 1 to 5
S function Change 1
T function Change 1
D function Change 1
H function Change 1 to 3
Signal(s) from channel (PLC)
Signal(s) updated: Cyclic
M, S, T, D, H information was output at the interface together with a new
value and the associated change signal. In this case, the change signal
indicates that the corresponding value is valid.
The change signals are only valid for one PLC cycle! This means that if the
signal is 1, then a change is pending for this cycle.
The value of the data involved is not valid.

Decoded M signals: M0 - M99
Signal(s) from channel (NCK)
Signal(s) updated: Cyclic
The dynamic M signal bits are set by decoded M functions.
For a general auxiliary function output, the dynamic M signal bits are
acknowledged by the PLC system program after the user program has
been completely run-through (executed once).
Spindle clockwise/counterclockwise rotation, switch coolant on/off
IS "M function for the spindle (DINT), axis-specific" (DB370x DBD0)

T function 1
Signal(s) from channel (PLC)
Signal(s) updated: job-
controlled by NCK
The T function programmed in an NC block is made available here as soon
as the T change signal is available.
Value range of the T function: 0-32000 ; integer number
The T function remains valid until it is overwritten by a new T function.
•
After the PLC has ramped-up.
•
All auxiliary functions are deleted before a new function is entered.
Control of automatic tool selection.
With T0, the actual tool is removed from the tool holder but not replaced by
a new tool (default configuration of the machine manufacturer).
