  1. Hi all, I've just started using Sysmac Studio for an NJ project after using CX-Programmer for many years. I'm finding Studio has a lot of failings compared to CX, not impressed so far: Can Studio to SFC? I can't seem to find the option, I thought it was fully IEC 61131-3 compliant? When opening files in CX it will open at the last point the program was edited at. Studio seems to open with all windiws closed. Using View/Recently closed windows option is a pain! Why can't Studio do this? CX ladder edi, I can just Ctrl dow arrow to create a parallel rung to add an instruction. Studio I have to right click to create a parallel path, with only an output as an option! If i want a MOVE for example I have to add that, and then delete the unwanted output? Ladder doesn't align rungs to the same length or create a new rung autmatically when I press enter on the previous rung? I find it powerful in some areas, but it seems slower to develop code on! And I can't force internal variables! Is it just me or are there solutions to these failings I haven't found yet? Rant over..
  2. Step7/WinCC and TIA Portal

    Hi Everyone, I'm currently programming Siemens S7-300 PLC's using Step 7 Pro v5.5 (mainly in STL including networking) and programming HMI's (Multi Panels and Touch) using WnCC Flexible 2008. I recently wanted to purchase a new HMI (Comfort touchscreen TP15000 version) and it say it requires WINCC COMFORT V11 SP2 (TIA?) for programming? I looked at the Siemens website about TIA Portal but found it about as clear as Siemens usually is, which is as clear as mud! My questions are: Is the software I am currently using being replaced by the two TAI portal versions? Or does one TIA portal version replace both Step 7 and Wincc? Can I use TIA portal to open my existing Step 7 projects or do I need to convert them in some way? Should I make this upgrade? Any clarity would be much appreciated!
  3. Archiving multiple projects

    Hi, I have quite a few projects in my S7Proj folder on an old laptop that I would like to archive before I upgrade my laptop. I can archive them individually (and have done with the important ones), but is there a way to archive the whole folder and all projects in one go? And also restore the folder on the new laptop in one go too? Siemens seem to advise against just copying and pasting the folder with Explorer. I'm using Step 7 Professional 2010 v5.5 Thanks!
  4. Symbolic Name Display

    Hi, To make Siemens code quicker and easier to navigate, is it possible to display the symbolic names of FC's, DB's etc rather than just their actual numbers e.g Valve_Control rather than a mysterious FC2 ? Surely you shouldn't have to look at the properties, or open the item to see what it does! Thanks.
  5. Can anyone recommend a cheap MRP (Profinet Compatible) network switch, such as the Siemens X108?
  6. Monitoring

    Hi, I've written a small program and am having trouble monitoring the running program. I'm connected over usb to an S7-300 CPU on the MPI port and using Step 7 Pro. If I monitor using a VAT the variables etc are all correct and update in real time. If I monitor the STL view they are all correctly in real time If I monitor the Ladder view or FBD view the view does no update the whole network leaving some parts in an unknown condition! Using the address tab at the bottom of the screen seems to work ok, but why not the other views! I've set the CPU protection to TEST. Any ideas? Thanks.
  7. Communication SFC's and SFB's

    Not sure about SFB 60, but AG_SND and AG_RCV use LEN and this is the number of bytes to be sent or received
  8. Efficiency - ST vs Ladder

    Same as Sparky, I find structured text much easier and quicker for tricky maths, especially when you have lots of floating point calculations. It's also better for fault finding as you can view each stage on one screen instead of scrolling through lots of rungs. It's especially nice to use in function blocks. Once the code is written and working you can just use it and forget about it.
