Overview of Alarms
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source symbol
Definitions: In motion synchronous actions, only special system variables are allowed on the left side
of the compare operation for the assigned variable as input and result variable of SYN-
FCT and as input variable for PUTFTOCF. Real-time synchronous access is allowed
here. The programmed variable is not a system variable.
Example:
DEF REAL OTTO, BERTA[2] DO SYNFCT(2,OTTO, $MN_...) ; Local variables or
machine data are not allowed as parameter for SYNFCT.
Reactions: - Correction block
- Interface signals are set.
- Alarm display.
Remedy: Modify part program. Local variables or machine data are not allowed as parameters for
SYNFCT.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 vari-
ables 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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 spe-
cial 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
Reactions: - Correction block
- 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.
