  1. Hi, (Edit: For convenience, the final solution of this issue is at the end of this first post) I am having problems with ethernet connection on V130 (33-R34) OS 4.4 (31) with V100-17-ET2 ethernet module. Problem is that sometimes (mostly random) connection somehow breaks and I am no longer able to communicate with V130 (using Visilogic) via Ethernet. To be more precise: Ethernet connection sometimes breaks after downloading the project (after RUN command is send). I don't have the data on how the Ethernet behaves when PLC is running for a long time - this project is new and I have been able to test it only for some days. But as for now I have never get disconnection while running "Online Test" mode or while downloading the project (just right after downloading). But while programing V130 and testing the project/program (for the past week or so) I noticed that after downloading the project sometimes Ethernet would work right away but other times wont. This even happens if there are no changes to Power-up setup of Ethernet. There is no difference If I Burn the project or just Download it. It happens when the PLC restarts and it’s about let’s say 80% chance that it will work and 20% that it won’t. Which is really frustrating because I cannot rely on this to be able to program or control the PLC remotely. What usually works to reestablish the connection is to power off and back on the PLC (not great) OR to just un-plug the Ethernet cable, wait a few sec and plug it back in. Sometimes I need to wait ~2sec before plugging it back in and sometimes ~5sec for the connection to work again. My initialization process is presented in attached file. I had shuffled the “PLC NAME”, “TCP/IP” etc. blocks in all combinations and nothing works. Maybe it’s a network thing (but if I recall it correctly I had similar problems when I started using V130 and learn how to use it on my home network, but I shrugged it off as “beginner problems. Nonetheless I added PLC IP and MAC on my DHCP list (as static address assignment), but this didn’t resolve the issue. How can I fix this issue? Any help appreciated. EDIT: Parameters of above presented blocks: It's pretty much the "default". Physically the other end of Ethernet connection is a router (build-in switch), right now I am using Visilogic (via wireless) to connect to PLC and sometimes Remote Access. EDIT2 (22.10.2018): I apologize for delayed responses but my replies are moderated and need to be approved by a moderator. Solution EDIT3 (19.11.2018): After hours of testing, downloading, changing cables, making cables I decided to try more routers. As is often the case, the problem was "easy to solve". It appears some routers aren't friendly with PLCs network card. I tested 4 routers: ASUS RT-AC1200G+, Fritz!Box WLAN 7360, Buffalo G54 and LevelOne (only a switch). All of these devices don't cause any problems while only PCs, Printers, TVs are involved. Everything works as it's suppose to. But, three of them: WLAN 7360, Buffalo G54 and LevelOne are not compatible with V130 PLC. If I connect V130 to any of those I get problems that are described here in this topic. LevelOne, Buffalo G54 were my old devices that is why I was having problems with ethernet when I started learning with V130. ASUS is my latest upgrade so I decided to bring all of these 3 devices to the site where V130 is installed and test all of them (WLAN 7360 was already on the site). It is strange that 3 out of 4 devices didn't work. Maybe there is a problem with some old devices or sth. Newer device (ASUS router) worked perfectly, right away with no modifications to the program. Debugging this kind of problem is tedious because one does not simply have 4+ routers to test with on remote sites. I am pretty sure this is a solution because I didn't get any error in one week of testing. Thank you all for your guidelines and solutions.
  2. I'm having trouble getting the scan function to work for CANbus Layer 2 functions with a V130. I have gotten the Send function to work (device functions), so I think my configuration is fine. When I run the scan function, the received data appears at the location vector (MI 37) but the data is never stored at MI 30. This is likely because MB 3 is never ON. When I run Online Test it shows MB 3 temporarily ON (as it should) but I'm skeptical if this is truly working. The CAN ID is correct. Am using the scan function correctly? Are there any examples of how to use the CANbus Layer 2 functions on the V130? Could there be any hardware problems? I have 120 ohm resistors at each end of the bus.
  3. Hi, I got V130 PLC, and I need to show some analog measurements on my display. When I try to type in russian, it just shows * no matter what I type. How can I solve this? Thankful in advance, Nikola Ljubinkovic
  4. Hello everyone, I'm new to this forum, and to Unitronics products in general, so I'm sorry if my question is too basic. The question is about navigating through displays on a V130. I'll describe my problem with an example, since the application I'm working on is far more complex than what I need to show you. Let's suppose I have an application with three displays (namely Disp1, Disp2 and Disp3). There is a jump condition on Disp1 and Disp2 which jumps to the next display when I press F1 on the keyboard. I.e., if I'm showing Disp1 and press F1, then it jumps to Disp2; on the other hand, if I'm showing Disp2 and press F1, it jumps to Disp3. The thing is that when I'm showing Disp1 and press F1, it jumps directly to Disp3 (which I think it happens because when it loads Disp2, as F1 is pressed, it jumps again to Disp3). How can I prevent this? I've tried several approaches and none of those worked. I've tried both creating some logic in my app which triggers a Load Display block, and using the Jump Condition table on the Link&Jumps tab of the display editor. Some background about me... I'm new to Unitronics products, but I've worked with other PLC brands, and I have extensive background in programming and embedded electronics. Thank you very much. Juan.-
  5. 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

    OPC Communication Slow

    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
  7. I am trying to use a pulse flow meter to measure the drain flow of a hydroponic garden system. We are wanting to use this to alarm if we have low flow in certain parts of the system. This is a low budget project so I am having to work with what I have. My V130 plc only has two high speed counter inputs and I would like to measure the pulse flow in four different areas of the system. So my question is, is there a way to read the low freq pulse of a regular digital input? The freq of this input would be no more that 20 pulses per second. I have been able to use a counter to count the pulses but I am not sure how to divide this number by a period of time. By the way I am new to programming. This is more or less a project for me to get some hands on practice. Thanks,
  8. Ok guys, first time attempting ladder programming here using a V130-J-R34. I am using AN0 to get signal from a 3-wire pressure sensor. Brown/Blue goes to +/- 24Vdc and the black wire is my signal. I get a 4-20 mA from the sensor and according to the default jumper settings of the V130 the AN0 is set to accept current as input. I am trying to perform a simple linearization to display how many bars my sensor reads. Since the memory of the analog input is 10-bit this is how I set it up: (see attachment) The logic is that being a 10-bit memory the max 20mA corresponds to DEC 1023 and min 4mA to DEC 204. Then this is converted to 0-10 bars. However it does not work. My MI0 reads always zero and the output MI1 is stuck at -25. Any ideas here about whats wrong? Cheers
  9. Hi, I`ve installed V130 with simple web server application, at remote facility. I ve succeed to connect remote web server from control centers PC and it looks like it is working fine but ocationally link breaks. Rebooting either remote router (HG531 v1 Firmware version HG531V1V100R001C90B017) or V130 recoveres the link. I ve set SB 168 already but problem persists. Is there any other way to automate lost link recovery process?
  10. Hi, I'm a new user and I've been trying to get a PTO pulse signal from one of the high speed outputs of my V130-33-TR34 to send to a stepper motor driver. I just got the PLC so it's set to default jumper settings. I pretty much followed the webinar on the Unitronics site and I'm pretty sure I did the wiring right (pin 1 on the transistor outputs to driver, pin 5 to PLC ground). Hooked it up to an oscilloscope and I don't get anything out. When I run the PTO move command, it turns the MB on for "PTO Move Success." Tried going into the HW Configuration and trying to get a PWM signal out by setting up one of those and initializing Frequency to 500, Duty cycle to 500 (50%), and then downloading a program with just ---|SB2|---(MB0)(S) where MB0 is the PWM "Run Bit" and still nothing. Anybody see something simple I overlooked or something I did wrong? If not, any ideas what might be going wrong? Thanks in advance
  11. I am trying to use an Interrupt HSC with a V130-33-B1 and a Ex-D16A3-TO16. when I try to upload the project to the PLC I get a message saying that Interrupt HSC is not compatible with my hardware configuration. I have looked all over documentation to find out if this is true or if i have something else configured incorrect, but have come up blank. Can anyone confirm that HSC on an expansion is not compatible with the interrupt? I know that immediate routines are not compatable with the V130-33-B1 but there is nothing about the interrupt.
  12. I just bought a V130-33-B1 and a EX-D16A3-TO16 expansion module for a project. I need to set up a HSC Interrupt but the project tells me that the hardware configuration is not supported. there is not documentation anywhere that says HSC interrupts are not supported with the 33-B1 is this true? I know that Immediate elements are not supported on expansion modules. Can anyone confirm or offer a work around?
  13. Hi, Here with attached my program which is half way done for test rig. I couldn't enter the values or even go to keypad entry mode. Please anyone suggest me what i did wrong. Thanks in advance. 19_10_13_TA24.vlp
  14. I am trying to input a String via HMI Keypad as MI -vector on V130 is there an example file ? thx
  15. I am using a V130-T4-TR6 and need to verify some information on the HSO output that seems contradictory between the tech spec and the V9.5.0 help file. Per the tech spec, the HSO freq. range is 5Hz to 200kHz. According to the help file, a value of 0 can be used but is not mentioned in the tech spec. It seems that the 0 value is used for a constant "ON" signal. Is this value available in the V130 and if so, please verify its function.
  16. Hello, I am trying to set up a V130 to send out text messages. I am using the Enfora modem and have set everything up correctly I believe. I am using COM1 and have changed the internal jumpers to RS232. I have the COM INIT 1 block running on power up with a baud rate of 9600. I have used the Modem Services to 'Prepare PLC-side modem' with a baud rate of 9600 as well. When I plug the modem into the v130 and cycle power the connection fails (ie SB81=1). Can anyone give me insight as to what I am doing wrong? Thank you, BenB
  17. Hello, I have recently posted asking about how to get the Enfora modem to connect to the v130. I was able to accomplish this by placing a number in the 'Number to dial' box in the modem settings screen. I just put in my cell phone number to test and the modem connected after that with a signal strength of 14. I do not know what the Number to dial should be set as though. I also am trying to send a text message and have everything set up to do so. Whenever I press the #1 button to activate the request to send the Modem Busy bit changes to 1 for a few seconds and then switches back to 0. None of the other status bits change when I do this however. I believe the request to send does change but is activating the SMS Send FB and is then clearing itself before I can see the change. Any help with this is greatly appreciated! BenB
  18. Hi, I'm having some issues regarding alarm acknowledge on my V130. I have a couple of alarms I would like to be acknowledged by a button connected to an input, the input sets a MB which is choosen in each alarm config as "acknowledge bit". I thought that this would acknowledge the alarm just as the selected MB goes high, but it doesn't work. Instead, the "F2" button is the acknowledge button, in the plc-project the "F2" button isn't used anywhere regarding the alarms. Is this maybe some default that isn't possible to change? regards Anton
  19. Hello, Thanks all for you help in this forums, I see lot of informations that I will use for my first project with Unitronics IHM. My application is simple for most of Unitronics user but for me it is a little "hard" My project : - I have a V130-33-R34 module with an interface IO-AI4-AO2 - I will connect 2 Ana 4-20mA inputs to the V130 and 3 Ana 4-20mA inputs to the IO interface. - I will use 2 Ana Outputs 4-20 mA to the IO Interface too. The application is to transfert the 5 analogic inputs to the modbus. And have the analogic value on one or several screen(s) only for local information. I am looking for the modbus programming as slave so I've found the example in the help documentation (file V130_Modbus_Slave.vlp) If I used this example, The PLC master could be able to read the 5 analogic input value by pointing The "MI" adress ? without other programming ? Is it possible to change the ID modbus adress by a V130 display and Variable and not by programming ? because in site this Id modbus adresse could be already used by other equipment. Thank you for your helps and knowledges. Stef
