Diagnostics
Diagnosis - Overview
When an error occurs, the defective IO device generates a diagnostics alarm and sends it to
the IO controller. To respond to errors with a defined (programmed) response, this alarm
calls a corresponding part in the user program (e.g. in the case of SIMATIC S7: organization
block OB 82 for the diagnostics alarm).
SIMOCODE pro V PN (GP) provides the diagnostics as channel diagnostics data records.
Channel diagnostics data records are generated as an alarm for
●
Selected messages (see Chapter Data record 92 - Device diagnostics (Page 229), PNIO
diagnostics column, marked with "1")
●
Warnings
●
Faults
●
Device faults.
Diagnostic status
The channel diagnostics is transmitted with different diagnostics states:
●
Maintenance required:
●
Maintenance demand (maintenance requested):
All SIMOCODE pro monitoring functions with "warn" configured as their response are
transmitted with this diagnostics status.
●
Failure:
All SIMOCODE pro monitoring functions with "trip" configured as their response are
transmitted with this diagnostics status.
Configuring the diagnostics response
The diagnostics response is configured with the SIMOCODE ES configuration software. The
global enable of the diagnostics can be set for the following events under "PROFINET
Parameters
→ Diagnostics":
Diagnostics for process events
Selected diagnostics events are transmitted with the "maintenance required" diagnostics
status.
See also Chapter Data record 92 - Device diagnostics (Page 229), diagnostics events
marked "1" in the "PNIO diagnostics" column.
Diagnostics for process warnings
All SIMOCODE pro monitoring functions in which the response has been configured with
"warn" are transmitted with the "maintenance demand" diagnostics status.
