Fieldbus Coupler Diagnostics

This section requires substantial knowledge of the CODESYS programming tool.
It only describes the procedure to create diagnostics using the fieldbus master.
Configured slaves (e.g., a fieldbus coupler or a fieldbus controller) are required
for diagnostics in fieldbus networks.
The DiagGetBusState() and DiagGetState() function blocks are available from the
BusDiag.lib library and the CANopenDiag() function block from the
WagoCANopenDiag.lib.

BusDiag.lib

To evaluate the diagnostics, you need the following function blocks from the
BusDiag.lib library:
• DiagGetBusState() for bus diagnostics
This function block provides general information on each connected slave
(e.g., number of slaves).
• DiagGetState() for participant diagnostics
This function block provides detailed information on each slave (e.g.,
information on diagnostics).
