Error identifiers
If it was not possible to execute a job, the failure is indicated by "logic 1" on status parameter error. The error
cause is coded at the block output State:
Configuration steps
To write NC variables, the same configuration steps are required as for reading NC variables. It is useful to store
the address data of all NC variables to be read or written in a DB.
State
