12572 Channel %1 block %2 %3 only permissible for motion synchronous
action
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: The predefined subprogram %3 specified here is only allowed in a block with motion synchronous
action. It must not be contained alone in a "normal" block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify program.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12573 Channel %1 block %2 motion-synchronous action: Call by reference
parameters not allowed %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source text area
Definitions: Call by reference parameters (keyword VAR) are not possible with technology cycles.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct PROC instruction of technology cycle.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12580 Channel %1 block %2 %3 not permissible for assignment in motion
synchronous action
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: The variable displayed must not be written in a motion synchronous action. Only selected variables
are permitted here, e.g. DO $AA_IW[X]=10 is not allowed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
Modify part program.
In a motion synchronous action, only certain variables are allowed.
E.g. $AA_IM, $AC_DTGPB
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12581 Channel %1 block %2 invalid read access to %3 while in motion
synchronous action
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: In a motion synchronous action, the displayed variable must not be entered as a variable that is to be
read on-line, i.e.
1. The displayed variable must not be written to the left of the comparison in a motion synchronous
action. Only selected variables are permissible, e.g. WHEN $AA_OVR == 100 DO ....
2. In a motion synchronous action, the displayed variable must not be used as a $$ variable, e.g.
WHEN $AA_IM[X] >= $$P_AD[1] DO ... DO $AC_VC = $$P_F
3. The displayed variable must not be programmed as an online evaluated parameter of a synchro-
nous procedure, e.g. DO SYNFCT(1, $AC_PARAM[0], $SA_OSCILL_REVERSE_POS2[Z])
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
