PvNodeFound
The "PvNodeFound" registers provide information about which nodes were detected on which channel (slave
identified successfully).
Data type Values
UINT See bit structure
Bit structure:
Bit Name Information
0 Not detected as valid 0 Node 0 (default mode)
Node 1 (multidrop mode)
1 Detected as valid
0 Not detected as valid 1 Node 2 (multidrop mode)
1 Detected as valid
...
0 Not detected as valid 13 Node 14 (multidrop mode)
1 Detected as valid
0 Not detected as valid 14 Node 15 (multidrop mode)
1 Detected as valid
15 Reserved -
PvNodeError
The "PvNodeError" registers contain the HART communication 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 Values
UINT See bit structure
Bit structure:
Bit Name Information
0 Detected as having no errors 0 Node 0 (default mode)
Node 1 (multidrop mode)
1 Error
0 Detected as having no errors 1 Node 2 (multidrop mode)
1 Error
...
0 Detected as having no errors 13 Node 14 (multidrop mode)
