The manual is unclear and there are some threads here but none that succinctly explain how to form the PLC
1) Get the current diagnostic state of the control (error, warning active, etc)
2) how to retreive the text of that message/warning/error
3) clear that error on the control.
The manual has a different overview than what currently exists on the control and speaks in generalities. An example showing the retrieval and clearing of faults would be extremely helpful.
