Disclaimer
Although ABB provides functionality testing on the products and updates that we release, you
should institute your own testing program for any product updates or other major system
updates (to include but not limited to code changes, configuration file changes, third party
software updates or patches, hardware change out, etc.) to ensure that the security measures
that you have implemented have not been compromised and system functionality in your
environment is as expected.
Upgrading
Device supports firmware updates via SD card.
Malware prevention solution
The M2238 device is not susceptible to malware because custom code cannot be executed on
the system. The only way to update the software is via firmware upgrades.
Password rule
The user must change the engineering password when accessing the engineering settings for
the first time. This engineering password must not include continuously increasing or
decreasing numbers (e.g. 12345678, 98765432) and three consecutive identical numbers are
similarly not permitted (e.g. 123444, 666888).
