PvCountHartRxError
Name:
PvCountHartRxError01 to PvCountHartRxError02
These registers are increased if communication errors occur on Layer 1 of the OSI model (e.g. transmission error
as per parity bit).
Data type
Value
UDINT
0 to 4,294,967,295
PvCountHartFrameError
Name:
PvCountHartFrameError01 to PvCountHartFrameError02
These registers are increased if communication errors occur on Layer 2 of the OSI model (e.g. faulty telegram
structure).
Data type
Value
UDINT
0 to 4,294,967,295

fully).

PvNodeError
Name:
PvNodeError01 to PvNodeError02
These registers contain the HART communications error bits. These bits are set if the connection to a node was
established successfully but the node at some point no longer responds as it should (e.g. the HART slave exceeds
the configured timeout / number of retries).
Data type
Value
UINT
See bit structure.
