Is there any new update available to ABB Protect IT REF542Plus Modbus Suite Program apart from its previous available versions 1.8 and 2.2?
Yes, there is the latest release v3.0 available on the website. You might need to log-in to access the full downloads of the software. It is recommended to take extra caution when you update these applications because they have multiple dependencies. This means that it's possible to update something and then to encounter other issues with another module. Follow the README instructions carefully.
