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

$A or $V variables are assessed in real-time in motion synchronous actions, i.e. in the
interpolation cycle. All other variables (e.g. user-defined variables) are still computed at
block preparation. It is not permissible to index the index of a variable for block prepara-
tion with a real-time variable.
Example:
DEF INT INPUT[3]
WHEN $A_IN[1] == INPUT[$A_INA[1]] DO ...
The locally defined variable INPUT must not be indexed with a real-time variable.
Program editing:
WHEN $A_IN[1] == $AC_MARKER[$A_INA[1]] DO ...
- Correction block
- Interface signals are set.
- Alarm display.
Modify program: Use real-time variables.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 variable %3 no system variable
%1 = Channel number
%2 = Block number, label
%3 = Source symbol
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.
- Correction block
- Interface signals are set.
- Alarm display.
Modify part program. Local variables or machine data are not allowed as parameters for
SYNFCT.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 variable %3 cannot be read synchronously with motion
%1 = Channel number
%2 = Block number, label
%3 = Source symbol
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.
