2.7 Firmware
updates
2.7.1 General
With the devices PXG3.W100 (all versions) and PXM40 / PXM50 (>1.15.30.497)
the firmware is updated in XWP using SSA-DNT; see E-learning module "Com-
missioning the web server". To ensure operation of the devices on the most current
firmware, the
current
firmware must be downloaded.
2.7.2 PXM
40/PXM50 ≤1.15.30.497
As a rule, the firmware of any PXM40/50s (referred to as “device”) can be updated
using the FWDT (Firmware Download Tool). This is particularly important if a FW
update is not possible via DNT (

issues. –
In devices with FW version ≤1.15.30.497, updating the firmware via FWDT
is
