ESCRIPTION
The following objects are available on the DPV1 field bus node:
Index 2: Module parameter
According to the format of the parameter telegram (see Parameter telegram section) you can pre-set
security and configuration values via slots 1-63 for every E/A module. The DPV1 field bus node monitors
the connection to the master. This makes index 2 a parameter deposited on the DPV1 field bus node with
reference to E/A modules.
Index 3: Control byte
The parameter telegram provides a user-specific byte for the DPV1 field bus node with which, for example,
the diagnosis format can be selected. However, in addition to transmission in the parameter telegram (byte
11, see
Parameter telegram section), it is also possible to pre-set the byte under index 3. This means that
you can re-parameterise during operation.
Bit 0 = 0 no stop in event of error (local bus)
= 1 stop in event of error (local bus)
Bit 1 = 0 automatic error acknowledgement (e.g. in event of peripheral errors)
= 1 manual acknowledgement necessary
Bit 3:2 = 00 Status PDU format
= 01 ID-related diagnosis
= 10 manufacturer-specific diagnosis (DPV1-FELDBUSKNOTEN)
Bit 4 = 0 DI16 and DO16 Format Byte 0 / Byte 1
= 1 DI16 and DO16 Format Byte 1 / Byte 0
Bit 5 = 0 Data exchange with Broadcast Operate
= 1 Data exchange without Broadcast Operate
Bit 7:6 reserved
Index 4: Acknowledgement (local bus event)
With index 3 (bit 0 and 1) it is possible to adjust the different behaviour in the local bus.
By default, the occurring peripheral errors are acknowledged automatically and the local bus, if possible,
kept permanently on Run.
However, depending on the application it may be asked that an automatic acknowledgement is not
permitted and particular measures must be taken. You can then react manually to bus events via index 4.
This applies for a module error in the form of an acknowledgement-binding peripheral error, but also after
the elimination of a serious error where data communication was no longer possible.
