tinuation
15420 Channel %1 Block %2 Instruction in actual mode not allowed
Parameter %1 = channel number
%2 = block number, label
Explanation The alarm is output in the following situations:
● When executing an INI file or definition file (macro or GUD), the interpreter has identified an illegal
instruction (e.g. traversing command).
● In a GUD file, access protection to a machine data with REDEF is to be changed, although an ACCESS
file (_N_SACCESS_DEF, _N_MACCESS_DEF, _NUACCESS_DEF) is available. Access rights for
machine data may then only be changed using one of the ACCESS files with REDEF.
● When executing the safety initialization program /_N_CST_DIR/_N_SAFE_SPF, due to the reduced
language scope that was configured for the purpose, an illegal statement was identified.
Response Interpreter stop
NC start disable in this channel
Interface signals are set
