Internal status parameter

Status variables
Every Ident block 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
block has a time stamp and an error memory to be able to better understand previous
problems.
These variables are stored in the relevant instance DB of the block.
