10.1.2 Validity range: Identification number ID

Function
The scope of validity of a synchronized action is
defined by the identification number (modal ID):
• No modal ID
The synchronized action is active in automatic mode
only. It applies only to the next executable block
(block with motion instructions or other machine
action), is non-modal.
Example:
WHEN $A_IN[3]==TRUE DO $A_OUTA[4]=10
G1 X20
• ID=n; n=1...255
The synchronized action applies modally in the
following blocks and is deactivated by CANCEL(n) or
by programming a new synchronized action with the
same ID.
The synchronized actions that apply in the M30
block are also still active (if necessary deactivate
with the CANCEL command).
ID synchronized actions only apply in
automatic mode.
Example:
ID=2 EVERY $A_IN[1]==1 DO POS[X]=0
• IDS=n; n=1...255
These static synchronized actions apply modally
in all operating modes.
They can be defined not only for starting from a
part program but also directly after power-on from
an asynchronous subprogram (ASUP) started by
the PLC. In this way, actions can be activated
that are executed regardless of the mode
selected in the NC.
