I/O diagnostics with Festo-specific extensions

The Festo-specific extensions for I/O diagnostics provide access to all available diagnostic functions in
accordance with the CPX standard.
The division into system, module and channel diagnostics provides access at any time to all diagnostic
messages (è Tab. 4.6). That means that no diagnostic messages remain undetected, even in the pres­
ence of simultaneously occurring faults.
