Version 2.4.0.x contains many new functionalities, such as BACnet server and client, platform markMX.2 and IMIO110, support PLC wall (Wago), new web server, SSCP over serial. Read more about the new features in the Properties of hardware platforms with Merbon runtime article.
With version 2.4.0.x and above, external HMI editor is not supported anymore, but the external HMI editor version 126.96.36.199 can be used to switch from older runtime versions (up to 2.3.0.x) to version 2.4.0.x. Read more in the Release notes. Please use the most recent Merbon IDE version if possible. The current version has several bugs fixed, and also contains fixes to increase program stability. The program supports OS with .NET Framework 4.7.2 or later – Windows 8 or later (Win8, Win8.1, Win10).
Repair tool and manual for RT uploat to PLCs: mark100, mark120, mark125, mark130, mark150, mark150s, mark150/485, mark150/485s, IMIO100, IMIO105, ICIO200, ICIO205. Tool must be used for uploading RT to listed PLCs with RT older than version 1.0.1506.47503 – the rightmost five digit number lower than 47503.
External HMI editor version 188.8.131.52, which is used to create and edit web panels based on older versions (up to 2.3.0.x) for use in PLCs with runtime 184.108.40.206 and higher, on PLC with Linux operating system (mark220LX, mark320LX, markMX.2, markMX, wPLC750-8101 and wPLC750-8102). It is used after updating the PLC from runtime versions 2.3.0.x. on 2.4.0.x. The internal HMI editor Merbon IDE in versions 2.4.0.x cannot import and process older graphic formats of the external editor based in versions 2.3.0.x, for editing older projects after the transition to the new version of the IDE it is necessary to use this new external HMI Editor. (A text menu can be imported; if the project does not contain graphics panels but only a text menu, this external editor is not required.)
