1.1 Software history

The "Electronic Revision" (ER) is consulted to document the revision status of electronic equipment according to NE 53 for all GDC devices. It is easy to see from the ER whether troubleshooting or larger changes in the electronic equipment have taken place and how that has affected the compatibility.

Changes and effect on compatibility

1	Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
	mistakes on display)
2-_	Downwards compatible hardware and/or software change of interfaces:
	H	HART®
	P	PROFIBUS
	F	Foundation Fieldbus
	M	Modbus
	X	all interfaces
3-_	Downwards compatible hardware and/or software change of inputs and outputs:
	I	Current output
	F, P	Frequency / pulse output
	S	Status output
	C	Control input
	CI	Current input
	X	all inputs and outputs
4	Downwards compatible changes with new functions
5	Incompatible changes, i.e. electronic equipment must be changed.

•It is permissible to lay the signal cable in water or in the ground.

•The insulating material is flame-retardant to EN 50625-2-1, IEC 60322-1.

•The signal cable does not contain any halogens and is unplasticized, and remains flexible at low temperatures.

•The connection of the inner shield is carried out via the stranded drain wire (1).

•The connection of the outer shield (60) is carried out via the stranded drain wire (6).

4.3.2Notes on field current cable C

DANGER!

A shielded two-wire copper cable is used as the field current cable. The shielding MUST be connected in the housing of the measuring sensor and signal converter.

INFORMATION!
