Number of unread entries
PNU
PNU: 204
Index: 5
Max index: 5
Class: Struct
Data type: int32
Values
Without unit
Default: 0
Minimum: −
Maximum: −
Number of new entries since switching on. FCT deletes the value after reading the diagnostic
messages. Every new entry increments the value.
o
The parameter value cannot be changed.
o
Writing permissible only in commissioning/parametrising mode with disabled controller.
ý
This parameter can be written by FCT without higher−order controller.
o
After writing, controller recalculation is carried out.
Current faults
PNU
PNU: 220
Index: 1 ... 3
Max index: 3
Class: Array
Data type: bitarray
Values
Default:
0000 0000 0000 0000 0000 0000 0000 0000
Write:
−
Current faults Each parameter is a bitfield consisting of three uint32 values and thus contains
3x 32 bits = 96 bit memory capacity. Each bit in this array represents a fault number. If it is set,
the corresponding fault message is active.
Example: PNU 220:01 = 0x00000001
Bit 0 set
E01 active
PNU 220:02 = 0x00000040
Bit 38 (32 + 6) set
E39 active
PNU 220:03 = 0x00030000
Bit 80 (32 + 32 + 16) set
E81 active
Bit 81 (32 + 32 + 17) set
E82 active
This representation is designed for evaluation by a PLC. Bit coding can be used directly to approach
an MMI. Fault texts, see section 4.2.5.

Current warnings
PNU
PNU: 221
Index: 1 ... 3

Values
Default:

Write:
−
Current warnings, refer to current fault messages (PNU 220). The distinction allows the PLC to
respond to faults and warnings specifically.
