Area of validity and machining sequence (ID, IDS)

Function
Area of validity
The area of validity of a synchronized action is defined using the identification ID or IDS:
No modal ID:
ID:
IDS:
Applications
● AC loops in JOG mode
● Logic operations for Safety Integrated
● Monitoring functions, responses to machine states in all modes
Sequence of execution
Modal synchronized actions that are statically effective are processed in the interpolation
clock cycle in the sequence of their ID or IDS number (ID=<n> or IDS=<n>).
Non-modal synchronized actions (without ID number) are executed in the programmed
sequence after execution of the modal synchronized actions.
Note
Modal synchronized actions can be protected from modifications or deletions by machine
data settings (→ machinery construction OEM!).

Comments
; If the actual value of axis Q1 exceeds 5 mm,
auxiliary functions M172 and H510 are output
at the PLC interface.
Non-modal synchronized actions in automatic mode
ID=n modal synchronized actions in the automatic mode up to the
end of program
Static synchronized action, effective modally in every operating
mode, also beyond the end of the program
