7.2
Parameterization of the diagnostics
Faults are reported by PROFINET IO through the generation of alarms. Alarms are output
using OB82. The alarm data can be accessed using SFB 54.
Parameterizing possibilities
Description of the alarm messages:
●
None
An alarm will not be issued in the event of an error.
●
Hard errors
Alarms are generated in the case of the following events:
–
Hardware fault (memory test)
–
Firmware fault (checksum)
–
Break in connection to reader
An alarm is generated and the SF LED on the S7 CPU is activated.
●
Hard / soft errors
In contrast to hard errors, in this case, errors are also reported that arise during command
processing.
An alarm is generated. However the SF LED on the S7 CPU is activated.
An alarm is generated when an event occurs as well as when the event ceases.
Incoming alarm
An event occurs and triggers an alarm. The SF LED of the S7 CPU is set as parameterized.
