12.1 Possibilities for error evaluation
Overview
● With the programming device/PC, you can read out the diagnostic buffer with the
parameter assignment user interface using Test > Error Evaluation.
– You will see the error class and error number along with plain text.
● You can evaluate errors in your program. The following options are available:
– The RETVAL return values in the instance DBs of the integrated FBs as a group
display for errors that occurred during execution of the FBs.
– The error bits of the jobs as a group display for errors that occurred while executing a
job.
– The error bit DATA_ERR as a group display for an error detected by the FM 352
during a write job.
– The error identifier in JOB_ERR, for the cause of an error during communication
between the FB and FM 352.
– FB CAM_DIAG for reading out the diagnostic buffer of the FM 352. Here, you can find
out the causes of errors in jobs and asynchronous events (operating errors, diagnostic
errors).
– Diagnostic interrupts for fast reaction to events.
