Analog part - Alarm and diagnostic
As soon as you've activated the diagnostic alarm release in the
parameterization, the following events can release a diagnostic alarm:
• Wire break
• Parameterization error
• Measuring range overflow
• Measuring range underflow
At accumulated diagnostic the CPU interrupts the user application and
branches to the OB82 for diagnostic (incoming). This OB allows you with an
according programming to monitor detailed diagnostic information via the
SFCs 51 and 59 and to react to it. After the execution of the OB82 the user
application processing is continued. The diagnostic data is consistent until
leaving the OB82.
After error correction automatically a diagnostic (going) occurs if the
diagnostic alarm release is still active.
In the following the record sets for diagnostic (incoming) and diagnostic
(going) are specified:
Record set 0 (Byte 0 to 3:)
Byte Bit 7 ... Bit 0 Default
