Diagnostic data
The analog module has diagnostics functions. The following errors may
cause a diagnostics:
•
Error in the project engineering res. parameterization
•
Wire break at current measuring
•
Measuring range overflow
•
Measuring range underflow
•
Wire break at current output res. short circuit at voltage output
When you enable the diagnostic alarm in Byte 0 of the parameter area,
modules will transfer
record set 0 to the superordinated system when an
error is detected. At present diagnosis, the CPU interrupts the user
application and branches into the OB 82. This OB gives you detailed
diagnostic data via the SFCs 51 and 59 when programmed correctly.
After having processed the OB 82, the user application processing is
continued. Until leaving the OB 82, the data remain consistent.
The diagnostic data uses 12byte and are stored in the record sets 0 and 1
of the system data area.
Record set 0 has a predefined content and a length of 4Byte. The content
of the record set may be read in plain text via the diagnostic window of the
CPU.
Record set 0 (Byte 0 to 3):
Byte Bit 7 ... Bit 0 Default
0 Bit 0: Module malfunction
Bit 1: reserved
Bit 2: External error
Bit 3: Channel error present
Bit 4: External supply voltage is missing
Bit 5, 6: reserved
Bit 7: Wrong parameters in the module
