Festo P.BE−CPX−CMAX−CONTROL−EN en 0908NH

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.

o

This parameter can be written by FCT without higher−order controller.

Current warnings

PNU

PNU: 221

Index: 1 ... 3

Max index: 3

Class: Array

Data type: bitarray

Values

Default:

0000 0000 0000 0000 0000 0000 0000 0000

Write:

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