  1. Edit: A little while after posting I had this thought....Lauka...are you talking about the PC version of Remote Op, or the mobile version? The mobile version only does what kratmel says. My comments were done thinking your were referring to the PC versions. Read on! I have to offer a contradiction here to kratmel. I can log into a 130 easily enough on Remote Operator. Also, and to quote from the help file: "This utility can be used with Vision, M90/91, and Jazz controllers. Enhanced Vision controllers require O/S versions 5.00 and higher; other series are compatible regardless of OS version." However, I haven't actually ever tried to connect to an M90 so can't assure Lauka that it will work. I actually prefer to use Remote Access, which can be set up very easily as multiple instances, which effectively function much better in real life. I had trouble accessing linked canbus units on RO due to name issues and in frustration gave up, likely too quickly! Remote Access also supposedly connects to lesser versions....Jazz, M90 etc, so give this a go, Lauka and come back to us with your results. You might have a connection problem, rather than the program playing up. For multiple instance setup, read all of the topic associated with this post: cheers, Aus
  2. I'm currently shifting a number of older puters up to 1903 via upgrade from iso, not clean install. I have another newer one that is always a clean install. These normally aren't involved in Unitronics stuff, but I'll try on a few once done and advise. cheers, Aus
  3. Agree with Gabriel. Also, it is possible that you have damaged something by not looking into all the parameters in the first place before connecting AC to something that is DC. This may account for the fluctuations you experience with the tester. You should be using the final CT product in your testing, not something that is different.....it's not much of a durability test if it isn't the product you're going to be using. Finally, ensure that you have all the wiring as recommended in the install literature. cheers, Aus
  4. Well Alex, I went there and hunted around a bit, but the only real bit of relevance is the main statement: ' This tool will configure the BACnet getaway as BACnet master and modbus Slave. If you wish to have the getaway act as BACnet slave and modbus master the configuration file should be change manualy before downloading it to the device. " (I have copied and pasted, so the spelling errors are actual! I need a holiday so wouldn't mind having a getaway with a slave at present!) I couldn't actually find anything on the page that actually says how to do this. Even if it is a simple change in the file, it needs to be fully explained. I am a bit incredulous that setting up the gateway via Vision etc defaults into it only being a master, with no easy "tickbox" to change this setting. To me this is a large error that needs fixing. cheers, Aus
  5. I can imagine. I hope you let support know of this issue. If it is a case of cost saving by going to an inferior product, they need to consider the ramifications. With Vision terminals I've only had instances of one poorly done screw thread that strips with the tiniest amount of torque, thus rendering the entire block useless. Often this is only found out onsite during final installation works. Very annoying if you don't have a suitable spare block on hand.....experience has taught me to always do this now. One time it was not a Unitronics product, but a complex 485 device fitted in a very awkward location, that only used standard screw connections. The very last connection point worked on was a total dud and meant changing the entire thing out.....grrrrr. Did the (very reputable) suppliers offer to pay for all the lost time and trouble in getting a changeover out of them? Ha!! I now check all screw actions on a device's arrival to the workshop. Life experience is a wonderful thing. cheers, Aus
  6. Thanks guys for the input, I'll go down the Vision path. cheers, Aus
  7. Mainly because Paul said he has been converting a program to the 350 for only a month. So in some ways it is sensible to have the 350 working on the very latest version possible at the time. It shouldn't have been the headache it was, which came back to bite him through doing something that he was well versed in. For what it's worth, I have always had trouble talking to anything Vision at higher than 57600 on all of the various versions of Windoze I have in use. In theory if the update now ONLY wants to run at 115200, and not shift itself back automatically to a lesser speed, then I consider that a potential problem. Sounds like further testing needs to be done at HO to ensure that things work OK in the real world. SB310 & 11 for the buzzer... I found this purely by loading up a 350 in Visi and perusing the System stuff. cheers, Aus
  8. @Cara Bereck Levy should hopefully pick this up. Paul, my immediate ask would be did it run itself as admin automatically, and if not did you try it manually? What was the connection type? No doubt we'll hear from Flex saying "why update" and I generally agree with this, but in your case it probably seemed sensible! cheers, Aus
  9. HI all, I have a small job on that I am sure I can do with a 130, but the cheaper option would be a low level jazz as it only needs 232 comms and a few outputs. The issue is that I need to find a string within a string that will come in now and then on the serial port. The main string that routinely comes in occasionally has a different header along with a particular sub-string that can be anywhere near the end of the entire string, and the overall string length always varies according to other inclusions. If both the header and the sub-string are there, the output actions will be triggered. Although I've worked with U90 for ages and don't think this is possible, just asking if anyone has found a way to do it? Or if it is blindingly obvious somewhere and I have simply missed it?! cheers, Aus
  10. Gerard, you first need a copy of Visilogic, get it here: https://unitronicsplc.com/Download/SoftwareVersions/Visilogic/VisiLogic_9_8_65.exe Once installed properly you can then consult the Help file and find Downloading/Uploading a Project under Getting Started. This details all the things needed to establish a connection...pay particular attention to the bits relevant to your type of plc, under "Enhanced Vision" and the "ERROR" bullet relating to using the inbuilt USB port. "Error" is a bit of a misnomer. Finally, although the installer is meant to do this itself, run the .exe above by right click the file and choose run as administrator. Once installed, navigate to the Visilogic.exe file within Unitronics Visilogic_C/Main folder in Program Files and right click/Properties/Compatibility tab/ Tick Run this program as Administrator (it it isn't already ticked....it should be) cheers, Aus
  11. In revisiting this after some zzzzz, also don't forget that Modbus addressing starts at 1, whereas Vision starts at 0. Sometimes you have to allow for this "difference of 1" when specifying the addresses. It depends on how the slave is set up....some also use the Vision style. Easy enough to find out for sure once you actually get a successful connection. Also, you have fallen into the trap of counts starting with 0...... MI4000-MI4027 is actually 28 MIs. cheers, Aus
  12. I'm only looking quickly and might miss something, but SB2 in your third rung is only calling the actual read on power up. You need this to be an actual call from other parts of your program, whenever you want it to happen. Would be nice to see the actual settings in Com Init 2. And don't use PLC Net ID, especially 0. If you look at the dropdowns that then happen, you will find preset determinations of what they do. Instead, do a direct store into SI8 of whatever unit ID number you want the plc to be. For Modbus I generally make the master "2". This allows for some later additions to a network that might default to 0 or 1. Your other understandings seem good enough, but no doubt I have missed something somewhere. Try my suggestions and see how you go. cheers, Aus
  13. And the final follow-on to all of this number talk. At first glance the calculator is a useful thing just to get your head around how Linearisation works. But it does have a "higher purpose" and that's why I did it. In the theoretical world, all 4-20 sensors work perfectly on those numbers mentioned. But in the real world, sensors, the plc's input or both can be slightly off. If it is a simple linear difference over the entire span, then a + or - amount to the result is all that is needed to get complete accuracy. However, if the span itself has some innate error, the calculator lets you play with numbers very easily to get the best match to adjust things. In all the sensors I use, many of my linearisations are NOT set at the numbers above, they have small variations to correct for this error. My "need no adjustment at all" percentage is probably 25% of the sensors in use. How critical your reading needs to be is an important factor in whether to play with this or not. In my case I have to have all temperature sensors perfectly matched to a master device, otherwise I can get control conflicts. In other situations this is not strictly necessary. cheers, Aus
  14. As I was writing my answer, Joe's has popped up and says it all. One thing I might add is to go this topic and get the calculator, which might help you understand some of the principles a little easier. cheers, Aus
  15. I wasn't going to chime in yet, but Simon has triggered me! Showing my age but in the old days we did it with what was colloquially called a wig-wag, and is still done in a lot of situations. I think the name came from old style railway crossing signals, and is the same principle. Pretty much a speed pot linked to an idler arm that was effectively Kratmel's "Dancer". (The funny names that all appear for the same things!) It was either sprung, or Gravity based which was the better system as it never breaks or gets turned off. That is why I was saying is PID really necessary? Correctly set up, they were stable and consistent. The KISS principle in action, instead of tech for tech's sake. cheers, Aus
  16. When I opened your project it immediately wanted the DB defragged. (So I didn't even look at it) If you opening it doesn't bring this up automatically, run it manually from the Build tab and then see how it goes. After downloading/burning the defragged version, don't immediately run it, do a full Initialise and Reset of the PLC and then run. cheers, Aus
  17. How is the load cell set up? PID might not be best for this at all. cheers, Aus
  18. I know what you are asking. However, as a sort of backup....... Doesn't your modbus connection/module/gizmo at the pump end have user settable I/O preferences that you can make them switch to if comms are lost after X minutes? cheers, Aus
  19. Hi all, This Topic will list items that are worth an easy find, but are not quite "pinnable" on their own. If we pin everything that is useful, it will all become one big mess on page 1 (or bigger!). I suggest that if you want something added to the list, contact myself or another mod to have them edit it into this existing list that I see as having carefully considered updating. To save space, only links will be shown, not full previews, with the Header listed before the link. HSC resets DW counter after power-cut http://forum.unitronics.com/topic/6118-hsc-resets-dw-counter-to-after-power-cut/ Multi Monitor (things disappearing) Issue http://forum.unitronics.com/topic/5827-multi-monitor-issue/ cheers, Aus
  20. Great that it is going for now. I'm showing my age here. Many many moons ago, I think in W95/98, a link like I suggested using cable was called ad hoc, and I still routinely call such a thing that name. Perhaps incorrectly. I had forgotten that these days the name seems to be solely directed at wireless....I guess cables are so old school! cheers, Aus
  21. What 130? Max pulse kHz rate? Have you completely read the Tech Specs on the DI8-TO8? There are limitations using this I/O for HSC. cheers, Aus
  22. + to everything already said. It sounds like you are in a location that has an IT administrator. ("scientist computer") Whilst you are learning this stuff, and to eliminate the possibility of the "scientist computer" person needing to do anything to enable the connection to work properly, use a crossover cable to directly link your PC to the PLC. Run your own little ad hoc network on the same numbers. If you don't know "ad hoc", a quick google (ad hoc networking) will point you in the right direction. One you are communicating ok and have proven a few things to yourself, then go back to hooking into the main network. cheers, Aus
  23. Some further info that might be of use to everyone. This method works on my W7_64 Pro system, but I don't know about other types or setups. I'm still sitting on 8.65 for the time being. I recently did some experimenting and noticed, as expected, that anything done on a later version won't open properly on file double click. Clicking ok on the "I'm not going to run" advice box closes things but doesn't really....you have to shut the process down via task manager. But once you've done that, double click opening the same file again brings up the "Visi not shut down properly" message box, and if I then select OK it gives me the "new project with old software, so we will open a new project" message. Click OK and lo and behold, instead of a new project, up comes the user program done on the latest version, but displaying in 8.65. This method might miss some subtle difference due to ongoing "capability upgrades" but it works well enough for what I need, which is viewing programs posted by forum members. I haven't actually tried this on an earlier version of Visi to see whether the same principle applies.....too scared I'll stuff something crucial up! Someone with a bit of time on their hands can give it a go. Hopefully this info might help someone out. Going backwards is sometimes an essential thing to do. cheers, Aus
  24. I've now had a quick look at your program and I think it needs a complete rethink. I would be changing it so that you have only one modbus sub, and you then trigger the various reads/writes via a counter method that also changes the locations/references in the Modbus blocks by using MIs. To me it is very clumsy bringing up essentially the same thing all the time via sub calls, and the more complexity the harder it can become to fault find. You also have some things that at a quick glance can be refined. You are using many sets and resets in the Main routine that I think are not needed. And set/resets can also be problematic. Split out your rungs!!! Line 14 in Main Routine is a classic example. And also whilst at Line 14, have a look at Vector Fill, which can reset all those MBs far easier in one hit. And you may not need them anyway! cheers, Aus
  25. am091, you might also like to have a look at this post (and topic), which explains the procedure a little. Not the type of file Flex is talking about, but one of the various options of writing to the card. cheers, Aus
