Net
The easy800 devices output information on their own operating state via ID
diagnostics contacts. This information can be evaluated in the circuit diagram
and shown on the display. To activate the display press the ALT button on
the device twice from the Status display.
EASY802-DC-SWD has no diagnostic contacts. EASY806-DC-SWD has the
diagnostic contacts ID1 to ID8. The following table applies to easy800
standard and EASY806-DC-SWD.

easy800 standard also has a group alarm for expansion units:
•
I14 = 0: expansion unit is functional.
•
I14 = 1: expansion unit is not functional.
10.3 SmartWire-DT
I13: Group alarm for SmartWire-DT
If an error occurs on the SWD line and the data exchange is therefore
interrupted, the group alarm I13 is set to 1.
Possible causes:
1. No SWD station present
2. Incorrect SWD station present
3. More SWD stations than stored in the target configuration
Diagnostic bits of the station
If an SWD station of the target configuration is missing in the actual
configuration, the PRSNT bit is set to 0.
If an SWD station of the target configuration is replaced by a universal
module, the SUBST bit is set to 1.
The PRSNT and SUBST bits are located in byte 0 of the cyclical input data of
the SWD stations (
