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:

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.
