Software architecture

All compact scales and terminals have a Flash memory chip on the digital board, which cannot be replaced. On these scales
the software can be loaded into the Flash memory via a PC (see Chapter 9.4).
The type of software depends on the type of scale. The various software versions are not compatible with one another. An
illegible display can indicate that an incorrect software version is installed. The various models of a particular series have
identical software (e.g. FTB 6 kg and FTB 15 kg).
On powering up, the scale carries out a display test in which the software version is also briefly displayed, e.g.:
"4-1.1.07" or "14-1.1.10".
The first digit designates the scale type and weighing cell
used:
7-x.x.xx: FTB and KMB-TM (ITB)
6-x.x.xx: FTC and KMS-TM (ITS)
5-x.x.xx: KMT-TM (ITT)
20-x.x.xx: Optional analog interface (can be inquired only
by printing out the menu settings)
The following digits (x.xx) designate the actual software
version (e.g. "1.07").
The type data for a scale are stored in a memory chip (EAROM) on the analog PCB (serial number, weighing range,
calibration data, etc. ). If there is a second weighing platform connected via the analog option, its type data is stored on the
EAROM of the analog option board (as well as all further settings in the "Scale 2" menu block). If the analog PCB (or analog
option board) is replaced, these data no longer match the scale and must be re-entered.
Note: After replacing the analog PCB of any scale, all user settings must be re-entered as these are also stored on the analog
PCB.
