12200 Channel %1 block %2 symbol %3 cannot be created
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Symbol in the source block
Definitions: The symbol to be created with the DEF instruction cannot be created because:
- it has already been defined (e.g. as variable or function)
- the internal memory location is no longer sufficient (e.g. with large arrays)
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Make the following checks:
- Check with the text editor whether the name to be allocated in the active program cycle (main
program and called subprograms) has already been used.
- Estimate the memory requirements for the symbols already defined and reduce these if necessary
by using fewer global and more local variables.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12205 Channel %1 block %2 area specification missing for GUD area
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The area specification
(NCK or CHAN) was not programmed in the definition instruction for a GUD variable.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Complete the area specification for the GUD variable definition in the GUD definition file.
The definition of a GUD variable must conform to the following syntax:
DEF <Area> <Data type> <Variable name> e.g.
DEF NCK INT intVar1
DEF CHAN REAL realVar1
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12210 Channel %1 block %2 string %3 too long
Parameters: %1 = Channel number
%2 = Block number, label
%3 = String in the source block
Definitions: - In the definition of a variable of type STRING, it has been attempted to initialize more than 100
characters.
- In an allocation, it has been found that the string does not fit in the given variable.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM
CORRECT. The correction pointer positions on the incorrect block.
- Select shorter string or divide up the character string into 2 strings
- Define larger string variable
Program Clear alarm with NC START or RESET key and continue the program.
