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.
Table A- 1 Status variables in the instance data block

Description
statLastErrorStatus DWORD This variable contains the last instruction
status if an error occurs. This value is al-

statLastErrorTimestamp DTL (S7-1200/-1500)
DATE_AND_TIME (S7-
300/-400)
This variable stores the time stamp of the
last error to occur (Last_error_status) with
the instruction.
You will find the status variables on the following path: "Instance data
