The register of the I/O module, which is
referenced by the type of signal and the
signal channel, contains a diagnostics
message. Details are available in the I/O
module documentation.
Module fault
The fieldbus coupler provides the status message diagnostic object in the event
that complex I/O modules can check their parameterization data independently or
if complex I/O modules are capable of providing extended diagnostic information.
In addition, all messages in conjunction with the iPar server are encoded in the
form of a status message.
A status message is structured as follows:
