  1. Hello to all, I am working on a new system where a Unistream B5 TR22 is a Modbus TCP master to 11 Samba PLC's Nothing to exciting but my biggest problem is a lack of knowledge. This is only my second project with a unistream PLC, with the first being a very straight forward ladder program without anything special. i do have a few years of experience with visilogic so that side is not a problem. What i already figured out is how to make the set-up on the master and slave side. the thing i don't get is addressing between the devices. In visilogic i could literally select which mb,mi,ml i wanted to read or write. Now i don't see that option. how does addressing work between these devices? At the moment i am still waiting on the unistream plc to arrive, so that i can try some stuff out, butt before it arrives i would like to make a little headway before that. kind regard's Leon Mötter
  2. Hello, I am just getting started on unilogic. I am having trouble communicating my USC-B5-B1 PLC with USL-070-B05 HMI. Can anyone guide me through the communication process ??
  3. I am getting the following error when trying to initialize/go online for the first time with my V570. ----------------------------------------------------------------------- "Communication over TCP/IP could not be established due to one of the following reasons: - cable connections are not secure - incorrect TCP/IP settings (IP address, Protocol type, Port number) - the connection is currently being used by another application. " ----------------------------------------------------------------------- Right now the first net in my main routine is checking SB2, following by Set PLC Name, followed by a TCP/IP - Card Init, (setting IP to 192.168.1.10), and then a Socket Init (using socket 1, TCP, port 20256, and client set to server [slave]). In communication and OS I have tried my connection as both TCP/IP (Call) & TCP/IP (Listen), I am using a favorite with the same name and IP as specified above. My local machine IP is set to 192.168.1.253. I am connected directly to the ethernet port on the V570 with the V200-19-ET2 ethernet com port I am trying to "stop-download-reset" to go online and I get the above error consistently. I'm sure this is a basic question but I have watched all the tutorial videos and read the help files and I believe I am doing everything I am supposed to, any advice would be great!
  4. Hello, if someone can help me it would be great! I just got the V-570 PLC and had it wired up to my inputs and outputs, and wanted to test it out. I have two issues I need to fix: First I tried to upload my project to the SD card, and put it in the PLC and run it. I wanted to see if I could just do basic screen navigation first. However, when I ran the program, after clicking on the first screen, it glitched out and turned a solid blue with no buttons. I figured it was a coding error on my part, but how do I take the program off of the PLC and restore it to the little animation sequence it had when I first turned it on? When I turn the maching off and on again it just goes back to the solid blue screen I had before. The second issue is, i figure to stop this from happening again I can debug it by the online test mode. However, when I followed the instructions to install the drivers and plugged the USB in, it said the port was not open and "may be used by another application". Is this a network firewall issue? I've attached the screen that comes up. If someone can help that would be great, I'm new to all of this and worried I might break something if I try to fix this myself. Thanks in advance!
  5. Hi all, it's my first post but I guess not least as I have a project to do using my Unitronics V1210 with CANOpen and 2 ports for Modbus RTU on board. I want to establish basic communication with my VFD (Vacon 100 / now Danfoss company) by Modbus RTU. 1. I bought RJ11 six pin plug and prepare junction so I have two cables - yellow at PIN1 and red at PIN6. 2. I connected PLC (Port 1) to VFD (A,B inputs) 3. I wrote a basic program to read the register 2101 (which is not 0 for sure) and... nothing happens. No communication. What I have checked: - Ports termination (set to RS485 with termination) - Galvanic connection between pins and end of the cable and it is ok - loopback test FB - no answer - ID, Baud Rate, Parity, Stop Bits - they are the same in drive and PLC I kindly ask if someone could check my ladder diagram as I have no idea what is wrong. KR, Bartosz
  6. Hello, I have the V700 with a Snap-In V200-18-E2B and a Inverter. I want to run a motor with a simple programs. I want the V700 communicate in RS485 with the inverter. I use a USB cable to send the program to the V700. I know i have to plug my RJ11 cables in the port of the V700 and set the communication on RS485 on the bottom of the V700. For the other part of the cable i have to take 2 of 4 wire and connect them on the Inverter. What i have to do after ? How i set the communication ? Will i have to create programs with contacts and coils to run the motor forward, or it have a compiled programs which contains some of these command ? Thanks,
  7. Hi, today in our company we received an ultra filtration system that comes with a V1040 on it. We've never had worked with an unitronics system before and we are trying to communicate the plc via modbus rtu over rs485 to work with our network. We configured the com port of the plc to work with rs485 as it was factory configured to work with rs232 but we can't reach it on our system, it's just showing of offline status. In the ladders we had a special subroutine for modbus, including all the registers and status of the system, we are reaching these points but it doesn't work. I'll attach some screenshots of the COM and modbus configuration and the modbus registers that i'm trying to read and i'll appreciate any help if i'm doing something wrong. Also, if i modify the program i need to upload it all or there is an option to upload only the com configuration without stop the plc? Due to the critic status of the process i only have a few minutes to stop the plc so i'll appreciate any shortcut to work faster on the system. As i said we've never worked with this plc before so we don't know the kind of responses of the system.
  8. Hello, For a new project, I’m actually trying to establish a Profibus communication between a V350 (slave) and a Siemens PLC (Master) S7 315-2DP. V350 (Slave - Address 3) -Profibus card is installed (V100-17-PB1) -OS is up to date (comprises a Profibus card) -Connected with a Profibus cable with Siemens connectors (terminating resistance connected) -Profibus configuration block on the main routine with SB2 (power-up task) -Status message = 0 -Error message = 1 -Profibus card detected : SB178 = 1 Siemens PLC (Master - Address 2) -Configured with UniProf.gsd file -Test with only 16 Int in Read and 16 Int in Write -Test with all Bit and Int in R/W … and no communication Can you advise me something ? or maybe do you have project example or documentation.. Thanks. Best regards, Fab
  9. I have three V430-J-RH6 PLC's, they will be communicating via RS-485. Each of these plc's are running two pumps for that specific unit. My end game is to make sure that none of the units have pumps running at the same time so we don't have power issues, ex. Unit 1 is running a pump so unit 2 and unit 3 cannot run their pumps until unit 1 is finished etc. I know how to program that part in but my struggle at the moment is with how to best get that information to each PLC. I need each PLC to have constant feedback of information from each other PLC. I need each unit to know when the other units are on and off. Is a struct command the best way to do this? If not what is, and how do I implement it? I have looked into the help files on Modbus master and slave for sharing information (read holding registers, and preset holding registers) but it doesn't look like they can share MB's between plc's? I also don't quite understand how those work. Any help in this would be greatly appreciated!! Thank you!

  10. Hello all. I'm new programmer with Unitronics PLC. At moment trying to communicate USP-104-B10 with VFD ATV630 series by Schneider Electric, but unfortunately for me unsuccessfully. In PLC communication created Scanner and Adapter, add strucs with global tags according manual https://download.schneider-electric.com/files?p_enDocType=User+guide&p_File_Id=9346677116&p_File_Name=ATV600_EthernetIP_Modbus_TCP_Manual_EN_EAV64328_03.pdf&p_Reference=EAV64328 But I do not understand clearly what I need add in Ladder to read all needed parameters, for example, every 5 secs and how to CALL it? Maybe one of you have example of program with successful communication? I would be very appreciated. Thank you in advance for your help and reply
  11. Hi All! I am new to actual PLC programming and ladder logic but I have been working with Yaskawa drives for 11 years and am quite proficient on that end. I have a V1210 and have found it fairly easy to work with aside from visilogic crashing quite often on windows 10. I really want to start interfacing VFD's via modbus rs485 and I am looking for a place to start. Are their any example programs or tutorials specific to the V1000 that could help me get a start? I did see another topic similar to this, but the links the support staff listed were broken. Thanks in advance! Kyle
  12. i so far finished my ladder programming in unitronics V1040 plc and created a webpage to use in raspberry pi to view the same HMI screen in my webpage at the same time whatever output i get from the Plc HMI. now i hv the problem is, how can i communicate plc and raspberry pi.can i connect the i/o and o/p of both plc and raspberry pi . is any coding ive to write in the raspberry pi terminal for the communicate with plc. please advice me.
  13. Hello! I'm trying to configure CanOpen communication between Lenze ECSxP Posi&Shaft and Unitronics V1210. I want to set the velocity and the position using PDO1. If I give a high level to the fifteenth bit the control word becomes: First 15 bits are control bits (begin from 0) The velocity value is between 16 to 31 bits it means i can store the value using MI. The velocity is effected in the process data telegram in percent of maximum speed. And the position is between 32 to 61 bits. It is carried out in the process data telegram in resolver increments. I want to give values between 16 and 61 bits It is not possible to use MI to store the position value i need DW, however...inside CANopen Configuration block for RPDO Tx i can use only MI only ML or only DW. Could you give me suggestions how to solve the problem?
  14. 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
  15. 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
  16. Hey guys, I have a UniStream 7" PLC connected with EX-RC1 expansion module via CANBUS. The CANBUS is connected according to the info in the datasheet with 120 ohm resistors and everything. The complete configuration that the PLC communicates with from left to right is as follows: EX-RC1, 3 x IO_D16A3_RO16, 2 x IO_ATC8/AI8, IO_D16_A3_RO16. The PLC and the EX-RC1 is grounded and connected as it should. EX-RC1 is programmed (initialized UniCAN) and the LEDS are all working propperly (PWR ON, I/O COMM ON, BUS COMM ON). Accordingly I am able to read/write all the inputs/outputs. So, the whole system and configuration is working propperly. A few (2-3) months later EX-RC1 dies (only PWR LED is ON). I can't read/write any of the inputs/outputs and the IO modules I mentioned earlier all blink ( no communication established). I tried restarting the whole configuration by turning the power supply OFF and then ON. Tried to reprogram the EX-RC1 but when the download starts it shows an error that the device is not available (not sure what the error said). So I thought to myself what the heck. It died, it happens and I replaced the module with a brand new one and installed a separate power supply used only for the EX-RC1. The whole configuration started working again, the comm was up and the PLC software was fully functional (able to read/write and execute). However a few months later ... surprise ... EX-RC1 dies again. The exact same circumstances. Is this a compatibility issue or? Thanks in advance for your help. Any suggestions/ideas are really appreciated.
  17. I'm trying to configure CANopen communication for a first time. NMT Status integer consists four values: 00, 7F, 05, 04. However when i press "Online test" the value is 517 (dec)?!?! - 205 (Hex). Please tell mi what it means, where is the mistake and how to fix it?
  18. Hello again, since your answers are very helpful and I could not find information I need on this forum, I`m starting new topic. I need to set up communication between V280 and multimeter DMK 22 by Lovato. Here is the tutorial they sent me: https://www.sendspace.com/file/trigbh(file is too big to be attached here on forum) I have several problems with understanding the whole communication. I have working MODBUS IP communication between PLC-to-PLC, where the communication is done through MODBUS R/W Mix, which I understand how it`s done. Here I need to get from the slave multimeter 3 values. First question: How do I send message to slave? The message should looke like this: 08 04 04 00 00 00 64 63 6A, do I have to send it as vector of HEX MIs? And the message I get back from slave will be vector too? If you don`t mind to explain this a little bit detailed including a little tutorial how to set it up correctly in VisiLogic, I`d be very happy. I have to solve this in 2 days. Thanks in advance a lot! Unitronics community is great and I will surely write it down to my thesis and recommend you. Best regards, Martin P.
  19. Hello, I'm using Jazz JZ20-R31 controller together with MJ20-RS add-on module for RS485 communication. Is there a way to use RS485 communication and simultaneously use a modem on RS232? To rephrase the question: I would like to achieve some sort of remote access to data while still communicating via RS485, are there any suitable options (modem, wifi...) ? Thank you, Best regards, Pawks
  20. Hello, I have a .net application that connects to a 570 via RS-232 using System.IO.Ports.SerialPort. Normally, it will connect. However, when playing with different baud rates, it sometimes does not connect until I connect the same PC with any Unitronics software (Visilogic or Remote Operator). My question is this: With VIsilogic, it appears that you can define the baud rate to anything in the connection properties and it always connects. How does the controller adapt accordingly? I think "out of the box", the rate is set to 115200. If I change my application to 57600, it failes to connect. But, if I connect using Visilogic @ 57600 it works. I go back to my application and then it works. I am trying to determine what Visilogic is doing that I am not. My connection looks like this: // Connect to the PLC try { string comPort = Properties.Settings.Default.CommPort; int comBdRate = Properties.Settings.Default.CommBdRate; int comTimeOut = Properties.Settings.Default.CommTimeOut; _serialPort.PortName = comPort; _serialPort.BaudRate = comBdRate; _serialPort.DataBits = 8; _serialPort.Parity = Parity.None; _serialPort.Handshake = Handshake.None; _serialPort.ReadTimeout = comTimeOut; _serialPort.NewLine = "\r"; _serialPort.Open(); } catch (Exception) { // Disconnect from the PLC _serialPort.Close(); } Once this executes, I begin sending PCOM commands: try { // Send the message out the serial port. _serialPort.DiscardInBuffer(); _serialPort.WriteLine(message); // Verify the message was received, catch the timeout string response = _serialPort.ReadTo("/A00SBF5"); if (response == "/A00SBF5") { //do nothing, success!! } } catch (Exception) { _connectionLost = true; _serialPort.Close(); return -1; } The _serialPort.ReadTo() catches the timeout (default 1 sec). When that occurs, we assume we lost the connection. Is there something I should be doing to prime the port first? Thanks!
  21. Hello, We have a problem with Unitronics Jazz 2 series PLCs (JZ20-R31, +adapters MJ20-RS) trying to connect to modbus communication line. The problem is we cant initializate RS-485 com port, every configuration are restored to factory default (9600;7;1;even;n) after RS-485 cable connection to PLC and in system menu it is impossible to change communication parameters if RS-485 cable is connected (RS-232 com port we do not use). We do not have any problems with Jazz 1 series plcs using almost same program, same configuration. + U90 ladder we are using last version (v6.4.9) + Unitronics 2 series OS is last version (V2.30 (B08)) + Communication line is good (we checked). + We have two Jazz 2 series plcs with same problem. P.S sorry for my english.
  22. Hello, Is there a way to read/write (send) data between 2 plc's via gprs modem, using pcom? I'm using V130 and Siemens TC65 at both ends Thanks in advance!
  23. hi, I have a project and require communication between a ABB drive and V280 unitronics, where v280 is the master, anyone can help me or suggest how I start? thanks, pd. I have done this type of communication but with other brands, this brand only cut I made the flight program without communication inputs and outputs only analog and digital.
  24. Hi, Can i MJ10-22-CS25 cable (programming cable) for modbus communication between my PC to M91-2-T38? thanks, Nikita1
  25. Hello! I can no longer download to the V570 via ethernet only via COM1. With 9.4.0, at the beginning happened once in a while and now I can no longer download the program in any way for LAN, I have to connect the serial network. I get notifications that communication fell after "Build info DLUs tables." The remote operator, online test from visilogic, webserver, Modbus, and other communication protocols are normal. I already sent the data to support and am waiting for support. Somebody had something similar, or any thoughts?
