Reason is that VisiLogic doesn't allow you to download a ladder application if the PLC OS is not the same as one in VisiLogic. What happens when I have to make some changes to an app which was made with an older version of VL? Of course, I could have many virtual machines with different VisiLogic / UniLogic versions, or use Version Swapper, but these are just complicated band-aids. Sometimes you need the new versions for new features, and they might even be mandatory due to security issues (introducing PCOM Passwords for example). I've never encountered an issue that old program doesn't work with a newer firmware, and I've done OS upgrades of some apps that I've made in 2008-2009 time. That's why I believe Unitronics will be consistent in never breaking things in the future, as opposed to IT where "move fast and break things" is the norm. Another reason is that I never know when the factory process is able to completely halt due to PLC being in stop mode. Sometimes the process or a machine can't stop for days. So, I like to keep downtimes at minimum, and upgrade as soon as possible. Once the OS is newest, I can later download a new ladder app without hitting a brick wall of having to shutdown everything for half an hour or so. I understand your concerns... I just like to keep things simple and tidy, and not worry about OS. -
Well, consider that usually there's only one pop-up open at a time so there should be no lag since you're not going to open many windows. The only problem is during desigh phase that you have to organize pop-ups on their dedicated layer... -
Personally, I believe this to be a huge mistake. PLCs are not like Windows computers & software. Sometimes there is a specific reason for upgrading (important and needed new feature being added, internet security, bug causing your particular installation problems being fixed, etc), but routine upgrading just because a new version is out - no. -
The RLO that is being sent to IF_GT is being set to the value of the result of the IF_GT, so if you just pass 1, then it will try to set the return value into a const. The IF_GT also doesn't return a boolean. You should rather do: int rlo = 1; IF_GT(rlo, RemainingCableLength, CurrentCablePosition); if (rlo == 1) { } -
