13 Firmware-update

13.1

Overview

®
UNIGATE IC has a memory for the firmware. It can be replaced via the UNIGATE
link-interface.
13.2

Execution of the firmware-update

The safest way for the firmware-update is the use of the basic board combined with the software
"FDT.EXE" (firmware-download-tool). These tools are available from Deutschmann Automation
(see chapter 15).
A Firmware-update can be carried out in the following operational modes:
Data exchange mode (via the IP-address UNIGATE
Konfiguration mode (via the IP-address UNIGATE
Firmware-update-mode (via the fixed IP-address 10.10.10.10)
13.3

Adjusting the firmware-update-mode

13.3.1

Adjustment by hardware

®
UNIGATE IC can be brought to the firmware-update-mode by the hardware. For it the signal BE
(boot enable) has to be pulled to the potential GND during the Power-up-process.
13.3.2

Adjustment by software

®
If the UNIGATE IC is in the configuration mode (see chapter 7.2) it can be brought to the firm-
ware-update-mode interactively through the command CTRL-F (0x06). After sending the com-
mand a security query follows, that has to be answered with J or N (J = Yes, N = No). After a
positive confirmation the IC is re-started in the firmware-update-mode.
13.4

Note on safety

The firmware-update should only be carried out when there is no other possibility left. A firm-
ware-update-process that has already been started CANNOT be undone. With it the previously
used firmware is permanently unusable.
13.5

Operation mode of the IC

Data exchange mode
This mode is required for the regular use of the IC. In this mode the IC will process all script-com-
mands and normally exchange the corresponding user data. The bus as well is operated in this
mode through the IC.
Configuration mode
In the configuration mode the UNIGATE
reset). After a successful self-test it will wait for further commands. Here it is possible to load a
translated Script into the unit or to configure the device.
