ESCRIPTION
Peripheral errors are errors that are triggered by their own E/A modules under particular error
circumstances. They can be acknowledgement-binding or non-acknowledgement-binding errors.
A non-acknowledgement-binding error can be, for example, the short circuit of an output at an IB IL 24
DO16. Non-acknowledgement-binding errors are revoked automatically when the cause of the error has
been eliminated.
An acknowledgement-binding error is generated, for example, when the electronic back-up at an IB IL 24
SEG-ELF is triggered. The error must be acknowledged. You can make the acknowledgement on the DPV1
field bus node either automatically or manually. The corresponding setting is effected on parameterization of
the DPV1 field bus node:

Manual confirmation may be effected via DPV1 (C1 and C2 master) or standard DP. In doing so (Slot 0),
Index 0004, sub-index 00 are written onto the DPV1 field bus node.
