  1. Go to Help/Example Projects through your PLC Program Best Regards, Nikola Ljubinkovic
  2. I keep that as my last option, but it seems like I have no choise. I will try that, and I will post results here. Best Regards, Nikola Ljubinkovic
  3. Yes you can. I'm using VisiLogic on my Win7 laptop (x64 bit). It works just fine. You can Enable/Disable your UAC if you want, but I don't think it will change anything. Best Regards, Nikola Ljubinkovic
  4. I have tried that, and it just shows blank display with backlight, but it should be showing text In debug simulation shows what text it should display, but PLC nothing, blank screen with backlight. When I power OFF device I can see backlight go OFF, and when I power it on I can see it goes ON, but without text that it should display. Just to say this, I have never open PLC backpanel, or experiment with anything like that. PLC has never left my desk. It was working normally for 2 months, and this happened. SB9 is bit that turns PLC Display's backlight ON and OFF it does not change my missing text problem (missing everything problem). I tried to find System bit or Integer that changes value of text somehow, but I can't find it. Is there bit like that on Jazz PLC's? I know there is for other PLC's, I just can't find it for Jazz. Best Regards, Nikola Ljubinkovic
  5. I have tried to hold down info key, it does nothing. I contacted some support, they told me to power OFF device, and hold info key and 7, then power it ON. As they said, it should reset PLC, and delete it's Operatin System. I did that, and connected PLC to my laptop. Downloaded it's Operating System again, and get same blank Screen, that glows a little. I have tried to download older OS, same thing happens. I put it back to newest OS. SB9 just turns OFF backlight, it doesen't help. I have made some screens, and downoaded them into PLC, and in online mode i tried to switch from screen to screen. SI2 (Current HMI Display) says that Screend are switcing, and in online mode that shows PLC Screen, i can see different displays, but PLC just shows same blank glowing display. I think it's hardware problem, but I am willing to try anything to fix this, before I contact my seller. Best Regards, Nikola Ljubinkovic
  6. HI, Thanks for such a quick answer, i wasn't able to find this System Integer, so i found on this forum that this integer is si7, tried to change that, it won't change from 0 to any other number. SI7 has no name in my U90 Ladder, I have newest version available. What is this Integer you said that I should change? Best Regards, Nikola Ljubinkovic
  7. Hi, I have Jazz PLC JZ20-J-T40, and i have 6 Screens on it. I have downloaded my program successfully, and PLC has been working properly for a wery long time, (two months to be exact). After I turned OFF and ON my PLC, it didn't displayed screens I have on it, so I thought that I have burned it, because of power or something. I measured power supply, it was OK, so I connected Laptop to PLC. I have successfully conected to PLC, and went online. I have some MBs on plc that i change using plc tasters, tried that, it works just fine. Everything works properly, except PLC Display. U90 Ladder has an option to debug display online, so I tried that on my laptop, it shows displays as it should, but on PLC just blank screen. I can see that PLC display is glowing a little, it just doesen't show any text that it should show. I have tried to download again, nothing changed. I tried to update Operating System, it says it's up to date. Is there a way of fixing this? Best Regards, Nikola Ljubinkovic
  8. My IP settings are: PLC1 (V130) PLC2 (Jazz) PLC3 (Jazz) I didn't post pictures for Jazz configuration, because, like I said, I used exactly the same configuration like they showed in example project for Jazz. My problem is not connecting to Jazz, when I connect one Jazz PLC it works normally. My problem is connecting two of them, second PLC just keeps reading values from first PLC. I tried with two different sockets, it gives me same results. But look at the socket configuration, it has 16 places to put addresses of 16 different PLC, I think it has to be able to connect more PLC's on same one. I didn't understand you, are you saying in order to connect two different PLC's, I have to connect/disconnect them manually? If so, this is not solution for me, those PLC's will be so far from each other, that this will be almost impossible. I need some solution that when I connect them, I no longer have to connect/disconnect them. Can somebody post project that has this configuration successfully configured? Thankful Nikola Ljubinkovic
  9. Hi, I have Unitronics PLC V130-J-TR20 PLC, which is a master, and two Jazz JZ20-J-T40, which are slaves. I need two of the slave Jazz PLC's to communicate with master V130 PLC. I have made configuration in PLC Program for read and write, but it's not working properly. When i set bit for request to read PLC3 (MB100), it reads it normally. But, when i try to read PLC2, it reads same value that I have on PLC3, although Communication is OK with PLC2. I have read example project, and used it to configure communication between PLC's, like you can see in the images. Regardless of what I do, one of the PLC's is not working properly, communication says it's OK, but keeps reading values from other PLC. IP addresses are different, of course, and i have typed them correctly into the MODBUS IP Configuration, like in the image. On my Jazz PLC's I have done everything like Example project in U90 Ladder says. Is there a way of fixing this? Thankful Nikola Ljubinkovic
  10. Also, I wanted to add this, My SCADA license is this on the picture I have seen that in order to connect PLC to SCADA I need to have specific driver for that PLC on my SCADA usb(License). When I purchased license, and connected it to V130 (Vision) via Ethernet, everything was working normally, but when i tried to connect my other Jazz PLC, that is when problems has began. I contacted you, and you give me driver to connect to Jazz, I pasted it like you said. Then I realized that Zview SCADA (From Zivan) doesn't have that kind of option (Or in my case). Anyway, this is what has happened. V130 has worked normally, until I put this driver you have gave me. Now eider Jazz is working, or Vision V130. It seems like Zview SCADA can only use one of the drivers for connecting PLC to SCADA. When connecting, on the very beginning, SCADA chooses one of the drivers, and that driver is either for Jazz or Vision. When it has successfully connected to one of the PLCs using one of the drivers, it just won't connect to the other one using the other driver. It is a big problem for me, is there a way to change some settings on zView SCADA in order to use both of the drivers I have, or there is some other solution? Regards Nikola Ljubinkovic

    Thanks for response Isakovic, I have tried to find setting like that on my SCADA, but i didn't have any luck. I will keep trying, but it seems like a dead end. Because of this problem, I am now trying to make my Vision 130 PLC read other two Jazz PLCs, and write them. Goal is to my V130 PLC communicate with SCADA, and other two Jazz PLCs. Problem with this is that if my V130 stops working for any reason, SCADA will no longer see any of my three PLCs, although Jazz PLCs keep working. Also this means that I will not se if my Jazz PLCs are broken if my V130 stops working. Anyway, this is my last option, although I don't like it. Can you give me some advice in order to make this (V130 master Jazz Slave) kind of connection work? Also, is there something that I should make on my Jazz, or V130 in order to get faster communicating with SCADA? Regards Nikola Ljubinkovic

    Hi, I have two Jazz JZ20-J-T40 PLC-s, and one V130-J-TR20 PLC. I am using zView SCADA. I tried to connect them via Ethernet by using switch, but I cannot use two different PLCs on this SCADA. Then i tried to connect them to SCADA via uniOPC, but communicating is just too slow. I have just one bit that goes from 0 to 1 in 0.5 seconds, and back to 0 in 0.5 (1 second pulse), just for testing, still it's too slow. It runs normally for like 2,5 seconds, and then just stops, and changes in 4-10 seconds, or just freezes for 2-3 minutes, and then changes. My PC Spec are not in the way of this, I am sure of that, i have tried it on my weakest and strongest laptop, still exactly the same results, too slow with just one bit for each of the PLCs, that is 3 bits total. Does anyone had the same problem, is there a way of fixing this? Regards Nikola Ljubinkovic
  13. Hi, I did everything like you said, but it's still not working. I have 1 Unitronics V130-J-TR20 PLC and 2 Unitronics PLC-s Jazz JZ20-J-T40. When I set everything like you said, Jazz PLC is working properly, but V130 doesn't . In attachment i have sent pictures with my settings for V130 and JZ20 PLC, on ZView SCADA. Just to make it clear, I can establish communication with only one of the two different PLC-s, but when i connect them together, one of them stops working. Either Jazz is working, or V130, but together SCADA just says port inactive. vuapp.ini
  14. Hi, I'm using Unitronics PLC JZ20-J-T40, and ZView SCADA. I have successfully downloaded my program into PLC, and tested communication via usb (Serial), and via Ethernet (MJ20-ET1). It's all working properly. Problem begins when i try to connect my PLC to scada PC. With USB everything is working normally, but it's not an option for me to work with usb connection. I want to work with Ethernet communication between PLC and SCADA. What should i do to make it work? Regards Nikola Ljubinkovic
