Output of auxiliary functions

Function
Output timing
Auxiliary functions are output directly in the synchronized action at the output time of the
action. The output timing defined in the machine data for auxiliary functions is not active.
The output timing is given when the condition is fulfilled.
Example:
Switch on coolant at a specific axis position:
WHEN $AA_IM[X]>=15 DO M07 POS[X]=20 FA[X]=250
Permitted keywords in non-modal synchronized actions (no modal ID)
Auxiliary functions in non-modal synchronized actions (no modal ID) can only be programmed
with the WHEN or EVERY keywords.
Note
The following auxiliary functions are not permitted in synchronized actions:
• M0, M1, M2, M17, M30: Program stop/end (M2, M17, M30 possible for technology cycle)
• M functions for tool change set with M6 or via machine data
Example
Program code
WHEN $AA_IW[Q1]>5 DO M172 H510

Description
actual IPO computation time
longest IPO computation time
shortest IPO computation time
actual IPO computation time in the ratio to the IPO clock cycle
actual computation time for synchronized actions over all channels
longest computation time for synchronized actions over all channels
percentage component of the total synchronized action
Run technology cycle
Inhibit
Enable
RESET of a technology cycle
Delete modal synchronized actions with the designation ID(S) in the part
program
Comments
; If the actual value of the Q1 axis exceeds
5 mm, output help functions M172 and H510
at the PLC.
