  1. 1) When editing IO Inputs or Outputs Alias Names directly (from the table view, without going into window for editing single tag) - cold not put a space symbol between words while writing (later when the whole "Input5AbracadabraOpenSesame" is written, you can, of course go back and put spaces in between words finally getting to the "Input 5 Abracadabra Open Sesame"). Problem is not observed while editing in single tag editor window. This is new mis-behavior, which was not observed some versions earlier. 2) In Data Table view - String literals are center-aligned without any obvious reason, which detracts from readability of large tables. For Number literals it makes sense to have them centered within cells, which more likely adds readability rather than destroys it, but it's a different story for the Strings. 2.1) In the same Data Table view - it is unable to directly edit anything without explicitly going into editor window for each cell with double click... That's so tiresome and time consuming for large tables. Exception is direct Paste, which however helps little, if each cell is slightly different. 3) Alarms - ID's could not be freely changed... I see no obvious reason for not allowing to do that because there are gaps still allowed (by deleting some alarms in the middle) and no automatic reordering of ID's is then happening. Of course it does not change much, but adds to the overall order and clarity of the project. Thus why not allow to change them freely, of course, with checking for duplicates. 3.1) Alarms could not be moved around (between groups for example). Took me few weeks to reorder entire system of 100+ Alarms... 4) Ladder function could not be duplicated, like almost anything other could. 5) The XY Plot is wrong type of thing, or at least I need a different flavor (see attached pictures): a) XY_Beijer is the reference - a single clearly visible point of arbitrary size is drawn for each feed in data sampler; the lines referencing these point(s) to the X and Y axes are drawn (switchable on/off); the background where any arbitrary function could be drawn or at least a clear background where any arbitrary picture could be put into (switched during runtime, not statically linked); b) there is always a cause - see the Weather_compensation; c) and a workaround - see the Comfo_Uni which is far from ideal, but at least works, somehow... Why all of this - I was asked to implement Comfomatic (Weather compensation for central heating) functionality as addition to primary functionality. Typically it is done in special hardware like Danfoss ECL series controllers, however the underlying mathematics is rather simple, so why not.... It worked out - making a usable user interface is a major pain on the Unistream platform.... d) of course in ideal world, I'd be asking the Unitronics team to implement the entire functionality in specialized function block, both for GUI as well as for Ladder, however I understand there are so many uses for these PLCs that implementing separate function block for each of them would lead to the same clutter which was seen in VisiLogic series software and which the Unitronics guys were presumably trying to avoid in Unistream. e) and there is always a workaround of the workaround - or better, I call it suggestion 2: The the simple Canvas control could be added to the GUI section - thus allowing users to draw whatever they need to solve such challenging tasks... (or if the screen is already a canvas itself, then at least allow to draw some primitives - dots, lines & rectangles from the Ladder (yes I know there is a Line element in GUI, but it is static, you can not even put a variable as its X1,Y1 and X2, Y2 points... thus it's unusable). 6) Each MODBUS target has the Modbus Remote Slave structure attached. This structure has very useful variable 'Fail' within it. It could be ideally suitable for checking for communication problems, and throwing Alarm to the user if any. But what's next - user cannot clear the alarm, because there is now way to drop it to the zero (I mean, there is no way to write 0 to this structure). Yes, of course there is again a workaround - copy the contents to another variable and then compare to it, not the 0, But why always a workaround? Why not do the things right the firsthand. 7) I'm still begging for ability to reorder members of the struct, like it's done in SMS Message composition with the List Of Text Variable - simple control to move members up and down. It has no meaning while the project is little and simple, but when it becomes large enough, when various functionality is added to different parts all the time, when structs determine what is written to different tables back and forth, then keeping various recent additions together with their primary counterparts rather than at the end of the struct, could be soooo meaningful. At present its a tremendous and very time consuming job to reorder the structs, by renaming and replacing every single appearance everywhere, when it could so easy be made to happen automatically. Not to mention, that is so easy in plain C, just cut one and paste above each other... Many thanks for the product already that great (light years away from said Vision or Samba), but of course, any improvement would be warmly welcome. P.S. Please double-check the communication with Cinterion BGS2T modem - it tends to drop from time to time (worse with USB-COM, better with UAC-01RS2, but still not ideal) and then it's unrepairable till the next complete reboot of the PLC... (re-initialisation has no effect).
