V6.B 18/07/03 Improvement of the reading of major alarm
" EEPROM DATA FAULT " appearing when much
access EEPROM is done:
-
Optimization of the readings in E2PROM (writing
of the value of the checksums in internal RAM).
- Replacement of the data storage circuit breaker
in E2PROM by a storage in safeguarded RAM.
- The function of access to the E2PROM becomes
protected from the interruptions.

V6.C 28/11/03 Software changes implemented in this version
- Addition of function SOFT/TOR: Function
allowing send a tripping order without awaiting
temporization of release, addition of manual
logical input closed (order of manual closing).
- Addition of function LOCAL/REMOTE by wiring:
addition of logical input LOCAL MODE (mode
switch-over local, for inhibition of the writing
orders the communication), and addition of exits
CONTROL TRIP (remote control of release) and
CLOSED CONTROL operate by remote control
trip).
-
Modif. treatment of the thermal model: 20
milliseconds instead of 100.
-
Evolutions communication MODBUS: addition of
the read quick byte (Function 7) by reading of
words (Function 03 or 04), and of the reading of
the date (on page 8).
-
Communication MODBUS Front Face: addition of
the filtering of address.
