%1 = Channel number

%2 = Block number, label

Definitions:

%3 = Source symbol

In motion synchronous actions on the left side of the compare operation, only special variables are allowed as input variables of SYNFCT and as input variables for PUTFTOCF. Motion synchronous access is possible here.

Example:

PUTFTOCF(1, $AA_OVR, 2, 1, 2)

The variable $AA_OVR is not allowed here.

Reactions:

-    Correction block is reorganized.

-    Interface signals are set.

-    Alarm display.

Remedy:

Modify part program. For the functions SYNFCT and PUTFTOCF only certain variables are allowed, for example $AC_DTGPW.

Program Continuation:

Clear alarm with NC START or RESET key and continue the program.
