12584 Channel %1 block %2 variable %3 cannot be read synchronously with
motion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: 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.
Reaction: 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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
12585 Channel %1 block %2 variable %3 cannot be changed synchronously
with motion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: When assigning SYNFCT in motion synchronous actions and result variables, only special variables
are allowed. Real-time synchronous access is allowed here.
Example:
WHEN $AA_IM[AX1]>= 100 DO $AC_TIME=1000. The variable $AC_TIME (time from beginning of
block) cannot be written
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program. Only certain variables are allowed for the function SYNFCT where real-time
synchronous access is possible.
Program Clear alarm with NC START or RESET key and continue the program.
