Overview of Alarms
NCK alarms
12586 Channel %1 block %2 motion synchronous action: type conflict in
variable %3
Parameters: %1 = Channel number
%2 = Block number
%3 = Source symbol
Definitions: Type conversion is not possible for on-line variables $A.. or $V.., which are evaluated or written in the
interpolation cycle. Only variables of the same type can be used together in logic operations or
assigned to one another.
Example 1:
WHENEVER $AA_IM[X] > $A_IN[1] DO ...
An on-line variable of the REAL type (actual value) cannot be compared with a variable of the BOOL
type (digital input)
The operation is possible if the following change is made:
WHENEVER $AA_IM[X] > $A_INA[1] DO ...
Example 2:
WHENEVER ... DO $AC_MARKER[1]=$AA_IM[X]-$AA_MM[X]
Improvement:
WHENEVER ... DO $AC_PARAM[1]=$AA_IM[X]-$AA_MM[X]
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program: Use variables of the same type.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12587 Channel %1 block %2 motion synchronous action: operation/function %3
not allowed
Parameters: %1 = Channel number
%2 = Block number
%3 = Operator/function
Definitions: The specified function / operator is not permissible for logic operations of real-time variables in motion
synchronous actions. The following operators/functions are permissible:
- == >= <= > < <> + - * /
- DIV MOD
- AND OR XOR NOT
- B_AND B_OR B_XOR B_NOT
- SIN COS TAN ATAN2 SQRT POT TRUNC ROUND ABS EXP LNX SPI
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
