15.2 Firmware
The device is equipped with one piece of software. This is the firmware image and its
related firmware version. The firmware is distributed as a downloadable file. The device
can be upgraded by placing the firmware image onto the device using the procedure
described in Chapter 12.
There exists exactly one firmware image for all L-IP models. The firmware has built-in
auto-detection of the fieldbus ports the device is equipped with. It adds virtual routers to an
internal channel. For the function of the device on the IP side this makes absolutely no
difference, as the IP connection is also tapped on to this internal channel.
15.3 Ports
This Section lists all ports, which may be used by the device. The ports are default settings
for their respective services. If not stated otherwise, the ports can be changed.
