ESCRIPTION

This section describes the composition of parameters for DPV1 field bus node and E/A module. If you wish
to parameterise via acyclical services, or if there is no interface available for easy parameter selection, you
must be familiar with the composition of the parameters.

For the DPV1 field bus node:

Byte 1 - 7

Norm DP

Byte 8 - 10 Norm DPV1

Byte 11

Control byte
Bit 0

= 0 no stop in event of error
= 1 stop in event of error

Bit 1

= 0 automatic error acknowledgement
= 1 acknowledgement via acyclical channel required

Bit 3:2

= 00 Status PDU
= 01 ID-related (module) diagnosis
= 10 old diagnosis

Bit 4

= 0 do not switch DI16 or DO16 data
= 1 switch DI16 or DO16 data

Bit 5

= 0 DXCH only when Global Control OPERATE
= 1 DXCH without Global Control OPERATE

Bit 7:6

= 0 Reserve

For modules:

Byte 1

Bit 7:6

= 00 ID start block for participants

Bit 5:4

Configuration
= 00 no configuration (e.g. for DO module;

the configuration value block is omitted)
= 01 configuration permanent

(configuration value block is analysed)
= 10 configuration briefly
(configuration value block is analysed)

Bit 3:2

security value
= 00 no security value (e.g. for DI module; since
the security value block is omitted)
= 01 zero issued (safety value block is not
analysed)
= 10 value retained (security value block is not
analysed)
= 11 adopt value from the data field

(security value block is analysed)

Bit 1:1

PCP

= 0 no PCP block
= 1 PCP block

Bit 0:0

reserve
