Issue

What is the minimum version of M340 firmware required to support full password protection for CPU and Application that was added beginning with Unity Pro V8.1?

Product Line

Modicon M340, Unity Pro, Control Expert

Resolution

It is always recommended to use the latest firmware that is available for up to date cybersecurity,  but for full password support a minimum Version 2.60 must be selected for the project and v2.60 or greater running in the M340.

Version 2.70 enhanced the functionality of password protection and should really be treated as the minimum, but they are fully configurable in v2.60.

Here is a link to the latest M340 firmware sorted by newest. (it is a long link to support the search/sort settings)
