Code 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 symb ols already defined and reduce these if necessary by using fewer global and more local variables. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
