  1. Windows XP SP3?

    What I've seen has been that the windows update version of SP3 is broken and will exhibit some of the problems you're all listing above. However, if you use the download version, it works fine. I don't know what the difference is, but that's the pattern we've been observing. I'm using SP3 here with 5, 500 and 5000 and they all work fine.
  2. RSView operator dialog box

    I'm not aware of anything preconfigured like that, but it shouldn't be too difficult to develop that little pop-up screen to do what you want.
  3. Windows XP Home/ RSLogix

    I believe, technically, RSLogix ~may~ run on XP Home -- but RSLinx does not. So, while it may run, you can't do anything with it...
  4. load cell to PLC

    There are also load cell signal conditioners. I've used Action Instruments WV448s. These convert load cell to 0-10VDC or 4-20mA. The only thing with these is that you'll have to calibrate the analog signal to the weight. The Hardy modules that rdrast mentioned are great! As are the MTs that Ken mentioned -- especially if you get one of the comm options (CNet, DNet, ENet, RIO, DH+, Profibus).
  5. indirect adressing with ML1100

    Are you sure??? While I don't have an 1100 to actually try this on, the software is allowing it, and it verified without error... See attached pic
  6. Those are great examples that you have suggested yourself. Try them -- if you need help, post what you have, ask specific questions, then we can help. We won't do it for you, but we'll help. The elevator, stop light, and washing machine applications are very typical samples that are used in training classes. They are very simple applications that we are all familiar with. Ken's agitator suggestion is also a very simple, real life application. The way to learn to program PLCs is to FIRST - before you do anything else - define what you want your system to do. This can be a flow chart, a sequence of operations, an outline... whatever it takes to define your system. Answer questions like "How does it start?" "How does it stop?" "What happens next?" "What if there is a fault?" "How does it restart?" "How does it reset?" Then -- AFTER you've defined your system -- you can start defining the hardware required to meet your requirements. PLC, I/O, communication networks, HMIs, etc. While you're doing this phase, make your system drawings and document all of your I/O. Then you can start programming. It doesn't matter what your system is -- it can be a stop watch, an elevator, a stop light, a blending system, an oil refinery.... The process is all the same. With practice, you might just do some of these steps in your head on a small project, but you still need to go through the process. I've been doing this for 20 years and still do it this way -- every time! So, for your stop watch: 1) How does it start? 2) How does it stop? 3) How many timers do you want/need? 3a) Do they need to run concurrently, independently, consecutively, whatever...?? 4) How do you reset the timer(s)? 5) What other information do you need to be able to completely define this application...???? See what I'm doing?? Try answering those questions here... we'll be glad to help you if you miss something or get something wrong. Then you can move on with the "How to do it" questions, then on to the actual code.
  7. Pcmk trouble with rslinx

    In RSLinx, make sure the selected Device Type is PCMK. There is no field for a hardware address on a PCMK config -- that's for the KT or KTX(D) devices.
  8. Top Doc For plc 3/10 on Win XP

    Best solution: Replace the PLC3. It's been obsolete for years...
  9. 1756-L61 program vanishes

    Which firmware version? It seems like there was an anomoly in one version that did this. Perhaps one of the 12's or 13's??? (Might be wrong... I'm out on the road, so I don't have access to all of those notes...)
  10. SE is an awesome platform, but it requires that you play exactly according to their rules. You can make absolutely NO shortcuts anyplace. Design you system according to their rules and it'll go well -- read the manual! Then read it again! After you have everything configured properly, the actual screen/tag development is just like anything else -- but the configuration MUST be done properly before you start.
  11. Sensing Plastic

    We blow stuff around in all of our plants. The easiest way to monitor is like Bob said -- monitor pressure. I've even done systems where we used the line pressure as the input to a PID that was controlling the rate we were feeding product into the blower lines. This was done to 1) prevent chokes, and 2) optimize throughput to conditions and distance transferred.
  12. CX-SUPERVISOR with Allen_Bradley

    Which version of Linx are you trying to use? To use RSLinx as a DDE server, it has to be one of the "licensed" versions. Not "Linx-Lite" that tags along with one of the RSLogix packages.
  13. How to Determine if CPU can be flashed?

    After you log into the AB site, this is the link you'll want for the chart. And the L32E is good up to v16.04.
  14. Rslogix 500 download only ver

    Doesn't exist
  15. Panelview Plus 600

    SLC504 doesn't do ethernet. It's either DF1 or DH+ SLC505 is ethernet. To work with the PVP600, you're going to need RSView Studio. If you have PVP600, then you have RSView ME (Machine Edition) as rpraveenkum said. Not RSView SE (Supervisory Edition)
