Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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]
Reactions: - Correction block
- Interface signals are set.
- Alarm display.
Remedy: Modify part program: Use variables of the same type.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 vari-
ables 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
Reactions: - Correction block
- Interface signals are set.
- Alarm display.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12588
Channel %1 block %2 motion synchronous action: address %3 not allowed
Parameters: %1 = Channel number
%2 = Block number
%3 = Address
