I'm busy with my first CoDeSys project and as far as the programming itself is concerned, I was up to speed in a couple of days. The program is based on an existing program which simply needs to be adapted - so far so good - and made more modular - as far as the program itself is concerned, also sfsg. Unfortunately, the Visualisation communicates via the %M Marker memory and is at present completely unstructured - one of the requirements is to structure the %M area more sensibly - and that's where my problem starts! I can't find any way in CoDeSys to identify or, even better, list used Marker memory. Since one of the objectives is to make it easier to port the program to different hardware, I don't even have a target, so I don't even know how much Marker memory is available - from the memory usage I've seen so far, I'm guessing 2k.
Is there really no way to identify which Marker areas have been used other than searching for every possible variation of the address?
By the way, the S/W is based on CoDeSys V2.1 (which is possibly part of the problem).
