What changes the value of Siemens equipment

Across this range, these are the markings that separate two units carrying the same catalogue number. Each part's own page says which of them apply to it and where on the label to read them.

Series letter

Printed on the label, usually right after the catalogue number, as "SER A".

Firmware revision

On the label as "FRN" or "FW", and on the module's own display if it powers up.

Option codes

On the motor or drive nameplate, after the base part number.

Tested or untested

Not on the plate. It comes from whoever pulled the unit, and it moves the price more than anything printed.

Hardware revision

Next to the catalogue number, often as "REV" or a bare letter-digit pair.
