Internal status parameter

Status variables
Every Ident instruction has status outputs to allow a suitable reaction in the user
program if an error occurs and to simplify error diagnostics on the device. In addition to
this, every Ident instruction has a time stamp and an error memory to be able to better
understand previous problems.
These variables are stored in the respective instance variable of the instruction.
