  1. Hello Everyone, I have just started working with Unitronics equipment and now I have to put a DSF60B to operate with a V570, the problem I am having is while the signal form the encoder is high the plc keep on inrementing value instead of treating it as a single pulse signal. To solve that i am using a Positive Transition Rise as my inputs and Incremental Block to read the signal from the Enconder. I have been told, and also imagined, that might be a better solution, just couldnt find it. I would appreciate if somebody could help me out with it. Thank you in advance.
  2. Hi, I have a very high speed air cylinder that uses a laser sensor to give constant position feedback to the PLC. The PLC then sends out an analog output signal to a directional control valve depending on where the cylinder is in its current stroke. The goal is to extend the cylinder to a certain set point and right when it reaches the set point I want the cylinder to stop. The issue is because of the extremely high cylinder speeds, the current cylinder position undergoes a big change after the PLC has already finished updating the inputs to memory. Also by the time the PLC updates the ou
  3. I am working with a unitronics vision 570 PLC. I am doing a burn upload project and then when I try to verify , there are two cross marks in verification. These crosses are against PLC DLU memory backup. Sp any suggestions on how to fix that?
  4. Hello, I have a school project where i was tasked to read an MI from a Slave PLC as a Master PLC. I've tried using the help fuction, but i havent seemed to make it work. Thanks in advance
  5. 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.

  7. Hello, In our laboratory we have xyz table for diode laser with v570 hmi controller. After the battery go dead, I have updated the firmware and uploaded the system file. Everything is ok, but the X and Y axis display negative values after the homming. How could I fix it? I uploaded vlp file to Gdrive. Thanks.
  8. Hello, In our lab we have xyz table for diode laser with v570 controller. After the battery go dead I updated v570 to the newest firmware and downloaded the system file. Everything is ok but the X and Y axis position status show negative values while I jogging in positive direction (after homming). How could I fix it? I have attached the vlp file. Thank you.

  9. Hi Guys, I have a new project to retrofit a mobile (vehicle) pile driver machine and I'm now in the process of hardware selection. The machine's decentralized control system was based on an obsolete CANopen Master controller made by IFM. It is a special controller for mobile machine applications and designed for harsh environments with excess vibration. Basically the question is: A normal PLC would be a reliable solution or should i use a controller specially designed for that purpose? What I'm thinking is to use a V570 (to be installed insid
  10. Hello, I have assembled a MODBUS RS485 network to communicate 2 inverters and 2 softstarters. When performing the tests of communication did not obtain success. When I removed the cable from the EX A2X or A1X module, it started communicating. I am using the COM2 port with the termination jumper.
  11. Hey all, I am new to Visilogic and I am trying to follow through tutorials. I am currently trying to interface a single EX-RC1 via CANBus to a V570. On the EX-RC1 I have a IO-DI16 and IO-RO16. I have tried to download the sample Visilogic programs to the PLC, however, I am not entirely sure if I am doing it correctly. I have flashed the V570_CAN Master for EX-RC1.vlp on the V570 successfully, however, the screen shows "COMM ERROR UNIT #2". When I tried to download the EX-RC1.vlp to the PLC it says "The PLC model selected in this project's Hardware Configuration conflicts with the mo
  12. My end goal is to send data over ethernet using the TCP/IP protocol to a raspberry pi. I already have the pi coded in python to look for a connection to its ip on a socket that I bound to it. My problem I believe is within the V570 PLC programming logic itself. I have initialized the card with ip and my laptop with ip Those two communicate correctly over ethernet. My pi is at ip The pi is bound to a socket and currently waiting for something to connect to it on port 8888. I initialized socket 3 on the PLC as a Master on port 20257 and set the name to
  13. Hello, I was asked to make a new software in a company where they had a 5-6 years (not sure) old V570 PLC (the one with the black/grey & white design, not the black one). This PLC does not contain the mini-usb programming port (regular used for charging mobile phones), but the one that is shaped like a square usb port (the one pc uses to communicate with printers/scanners). Although I had the driver installed for the more common usb port I also used install usb driver option from the visilogic software, and the software confirmed that I already have the driver installed. However when
  14. Hi there, I try to initialize Enfora modem PC-side. I followed all of the steps from the tutorials on the Internet. I tried different Baudrates, tried Hyperterminal... When I use Baudrate of 9600, and the AT commands defined in the Modem Services, all of the commands are successfully completed and when it comes to the end it always says: Modem could not be initialized. Do you have any advice what can be the problem?
  15. Hello there! I'm trying to drive DC Motor with PLC V570 via PWM. This is for my diploma thesis so I want to do it nice and design PID controller in Simulink Matlab. In PLC I want to do identification of the transfer function for this system with step response. This is the first order system, so it shouldn't be a problem. Than I'm going to use this transfer function in Simulink to find PID parameters. At the end, I got P,I and D parameters from Simulink, and I don't know to transfer them into PLC. For example for closed loop system with discrete PI controller in ideal form P(1 +
  16. Hi I am trying to connect to a scada network on a V570 using Modbus IP. No success so far. I have attached a screen cap of my ethernet startup (couldnt get it to paste direct). Could someone please have a look and see what I have done wrong. Thanks Paul J V570 Modbus.pptx
  17. Hello, I am working on a project were I am using a vision V570 and a module EX-D16A3-TO16, the problem is that when I turn on the equipment all the inputs are active, but I do not have connecting even a single input. I am new with Unitronics OPLCs , so far I just worked with V350, and it is the first time I am using a EX module, which could be the reason for this to happen? Thanks
  18. I have attached images to this post below... Basically I haved a V570 (with the ethernet addon) which was last used about 5 years ago. When I powered it up, I got a no loaded application error. I have tried going into visilogic, with with default baud rate settings, and the settings shown on the display, but i just cant get access to it. I also am using a 4 wire RJ11 cable ( I have no programming cables left). Could this be the issue that I cannot connect? Or is it because the PLC is in stop mode? I have tried connecting via ethernet, but my lan adaptor wont let me use the subn
  19. I have 2 V570's that i would like to setup to mirror each other. i have 1 setup with 2 modbus ports (1 & 2) port 1 is connected to a PC via modbus as slave port 2 is connected to another V570 Via modbus as master the second PLC is setup with port 2 as slave I'm to receive data from the pc and have both PLC's make changes to the data and send it back to the pc the first PLC is getting MI 100 - MI 132 and MI 200 - MI 232 and MI 1000 - MI 1045 from the PC and sending the data to the second PLC at the same MI addresses the second PLC is receiving the same MI's from the first PLC a
  20. Hi, i have a V570 that i put a program on and it was working good until i recycled power to it and now the PLC is in stop mode with no application. i cant connect to it anymore. is there anyway to reconnect to the PLC?? Thanks.
  21. I know some people have been looking for an alternate method of accessing the microSD without opening their cabinets due to environmental and/or hazard conditions. Recently found this: http://www.amazon.com/48cm-Sd-micro-Card-Extender-Cable/dp/B007WYRO7O while researching some options. Planning on picking one up and doing some testing to see if it responds without issues and doesn't affect the SD card reliability and retention.
  22. I have a project were I am using an Enfora GPRS modem to make IP calls back to a web connected machine. This works very well and I have set it up to receive text messages via GSM. I want to use the received text to trigger a call back on GPRS to an IP specified in the text. I have found the function to convert the IP to a text but not text to IP. Is there one? If not how is the decimal storage of an IP formatted so I can do via math / string functions? Thanks in advance Andy

  24. Is it possible to dynamically change the drum step time through user input? For example, link it to an MI so that the time is adjustable based on recipe, or would I need to use a 0 time step and a timer to control moving to the next step?
  25. Hello, I'm doing a project where I have to save alarms to SD. I have a V570 with 2GB SD card (The SD Card is formatted with SD Card Suite). I set the SB352 (Write alarm history to SD) and it does that, it writes alarms directly to SD card. If I have some alarms in buffer (SI76 value is greater then 0) and I set SB352, the value in SI76 clears and ALARM.UAL is increasing in size. So I think the alarms are written to SD Card. The problem is when I use the FB "Show alarms" with "Alarm history" option. It shows the history, but after a PLC Init and Reset, the history is cleared. It shows the
