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.
10.4.1

BusDiag.lib

The following function blocks from the BusDiag.lib library are required in order to
evaluate the diagnostics:
• DiagGetBusState() for bus diagnostics
This function module provides general information on every connected slave
(e.g. number of slaves).
• DiagGetState() for subscriber diagnostics
This function block provides detailed information on each slave (e.g.
information on diagnostics).
