Useful field checks
These improve the value of one captureCapture useful examples of: an existing current fault via Print Faults; a local Fire Test activation and restore; the same from another network node; a normal fire only if it is already part of an authorised site test; a device fault/restore; and any event whose Node/Loop/Address is missing or parsed incorrectly. The exact HEX is the most useful data for protocol/parser work.
