4.3.5 Module Status Messages
A module status byte is added to each module’s process data (with the exception of safe I/O
modules). It describes the status of the module including the following information:
Module Status Messages in an EPXETC001 Station
Plug-in station is undefined
Plug-in station = module OK
Plug-in station empty, module has been removed
Incorrect module plugged in
4.3.6 Module Diagnosis
The network adapter`s status word reveals whether there is a module diagnosis. The history of the
module diagnosis can be interrogated via object 0x10F3. A ring buffer stores 20 diagnosis so that the
current diagnosis overwrites the oldest one (subindex 06 to 19).
