Firmware update
To update firmware of the HT104 terminal, open the web page https://domat-int.com/en/downloads/software and get the latest HT104 firmware and then open the web interface of the terminal by entering the terminal IP in your web browser. In the HT104 web menu, click "Administration" and select "Choose file" in the "Upload new firmware" section. Select the firmware file, and click "Upload new firmware". Do not power off the device and do not remove the Ethernet cable when the update follows. After finishing update, the HT104 restarts automatically.
Runtime status indication
LED RUN indicates the runtime status using a sequence of short flashes. The error code persists the power off / on cycle, it is reset only after a project has been uploaded.
Normal state: LED flashes periodically 1 s ON, 1 s OFF – no errors
Error state: LED flashes in a pattern of
- M short flashes (300 ms ON / 300 ms OFF), where M is the upper code error order
- 1 s OFF
- N short flashes (300 ms ON / 300 ms OFF), where N is the lower code error order
- 2.5 s OFF
Meaning of the error codes:
- 11 memory low for OS
- 12 memory low for runtime
- 13 stack overflow *
- 21 corrupted / bad RT image
- 31 HardFault *
- 4X watchdog of client X expired
- 51 system file system error
- 52 web file system error
- 53 system FS error - reset of IP address, saved variables were erased
- 54 users FS error - WEB files need to be uploaded again
- 6X - file system full
* at these errors the PLC stops and the LED starts to flash after power off and on.
