  1. Hello to all. I am working on a project in which I will only get PLC data to an external control system, we will do it in MODBUS. Everything works correctly, but I find two problems: The addressing mapping is 1: 1 accessible from MODBUS, so they could read any record. The same is reproduced in writing, so that accidentally (or not) they could overwrite important values of my program. Could we limit the reading to a certain number of records? Could we limit the writing? Thanks in advance!
  2. Hi All, I'm using a VT570 to log some data to SD card. I realized a single Trend with 2 curve for 2 sensor. My goal is to log on a monthly basis this data on a file. File name is "MMYY.utr". Sample rate is 1 data every 5 minutes. When I export data from SD to Excel using the appropriate tool I always have DateTime column rollback in a strange way. All the datetime are correct till to 25th of month and then they are wrong (even if the logged data continues to be correct). Here under you can find some screenshots that I hope explain the issue better than my words. Ladder code is simply and It is essentially a copy of Visilogic example to save Trend on SD Card but I'm not able to understand where is the error. Any help or advise will be very appreciated. Regards Golzione
  3. Hi, I try to build project with new V700 panel. Large display make possible to use large buttons and fonts visble for user without glasses . Application in V700 is disigned for users with age above 50. But alarm display in V700 has small font and little buttons. Stylus must be used. It is hard to use V700 alarm display without magnification or glasses. Is it possible to switch font or resize embedded to V700 alarm display buttons?
  4. Dear all, We communicate 10 nodes through rs485 communication in v700 port 1..the problem is if my one divice is failture means other 9 nodes getting delayed..kindly provide solution RegArds Mohamed
  5. Greetings all. First round setting up a RTD and, after reviewing forum posts here, I believe I am more confused than before... but likely an easy answer for most around here as I'm much more of a software guy. Our setup: V700 Model with an RTD going to a IO-ATC8. I do not have the RTD model# on me at the moment (typing this after hours but can provide tomorrow) but I know that the RTD contains a Prosense XTH-0300F-PT1 transmitter (0-300 degree F even though the RTD itself is capable of a much larger but unneeded range) I understand that the IO-ATC8 is 14bit. The confusion: I've seen forum posts where the linearization block references the "resolution @ 4-20mA" stated by the RTD/transmitter (I cannot locate this on the spec sheet for the model listed above, or maybe it's called something other than "resolution" but means the same thing?). I've also seen where the linearization is based off the 14bit module (3277 - 16383) - which is in line with what we did with level sensors... aaaand I've seen where, in other cases, an RTD does not require additional linearization (other than dividing by 10, but I assume this is for 10bit setups?). Any advice would be appreciated with a layman's outline of rationale. Cheers!
  6. So on the V700, whenever a numeric keypad is pulled up, I have to touch the top half of the button to get it to register. this can be kind of frustrating, because the buttons are long and narrow and it usually takes a couple tries to get it to work. I know its a software issue because there's a border that surrounds the touchable area when the button is pressed and it only covers about 60% of the button. when the button is pressed in the center, it does not register.
  7. 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,
  8. dear sir, i have 4 vessels having individual plcs model is v700, Each plc having individual festo valve (16 way digital outputs) in tcp/ip protocol, my first plc ip is 192.168.1.50 and my festo ip is 192.168.1.1 my second plc ip is 192.168.1.51 and my festo ip is 192.168.1.2 my third plc ip is 192.168.1.52 and my festo ip is 192.168.1.3 my fourth plc ip is 192.168.1.53 and my festo ip is 192.168.1.4 Question 1 : How to handshaking all plc in one loop (ex: i want to transfer my first vessel product to 2nd,3rd and 4th vessels.) regards, Mohamed
  9. Hello, Is there an alternative to system registers SI103 - SI106 (TCP keep alive) for V700? I guess SI103-SI106 don't have a function in V700 since there are only 4 of them? Correct me if I'm wrong. Or do I have to make this function myself?
  10. Greetings all. We have started a minor project at work and we are, admittedly, pretty new to doing any sort of networked communications from PLC to PLC. We have 3x V700 currently and what we hope to accomplish is simply to have (perfect world) a full rendering of the remote HMIs on each of the PLC. Therefore, PLC A would have a link to go to PLC B's HMI and another link to go PLC C's and be able to see the HMI as if standing at that PLC - akin to the iOS remote operator app or using the Windows remote operator software. The question in the end is has this already been easily implemented in some way? Otherwise I assume we would have to use TCP/Modbus or UDP_Raw to pull in valves from PLC B and PLC C but have the HMI of the remote PLC be copied into PLC A's project files. Doing so would make it tedious to keep up with changes to the other PLCs to back implement in the PLC A's code so that the HMI would look correct and all the variables continue to match. If anyone has tried to do a complete remote HMI mirroring / remote op from a secondary PLC, please advise on any tips that might point us in the least painful direction. Cheers!
  11. We are trying to connect to a Vision V700 unit by ethernet for remote access, and to confirm the ethernet is working before starting the program block where we will be sending commands to another device over ethernet. The model I am trying to connect to is as follows: Every time we try to connect over Ethernet, we get the following error message: I have checked the cable connections, confirmed that the PLC Name, IP address, and port number set for the PLC match those that the computer is looking for. I cave confirmed that the UnCmDrv1.dll driver is installed on my computer. its last log message, timestamped to match my most recent remote access attempt, shows the following: Trying to read the SB values over a USB remote lin does not help much, as many of the bits assigned to ethernet protocols and statuses are annotated (not relevant for V700). What am I doing wrong? Why won't an Ethernet-capable PLC connect to the company Ethernet network? Thank you in advance for your assistance.
  12. Hello everyone, I'm still learning with this hardware. I am working on a project for which I need to totalize a flow that comes from an analog signal. I wonder if there is a function block that does it, or how to do it. Thank you!
  13. Hi! My plc is a V700. I went to the Sd card for analogue signals. I would like to send the exel table to FTP every 5 minutes. Can an example program be made for me? This exceeds my knowledge Thanks very much for the help!
  14. Is there any way to see which Ethernet socket is active on V700? I went with V700 because it has integrated Ethernet port, but now I can't use SB 147-150 like on other models that require expansion card.
  15. Hello, These days I'm having a problem using modbus to reading pressure data from TROX terminal unit. It is kinda simple idea - 7 slaves (TROX units) and V700 is master and gets all the data. But as I'm conneting modbus though all of them I get error that there is no connection between TROX units. Slaves ID are set properly, cable polarity have been checked too. Maybe there are some other problems that I don't know? Thank you kindly for answers.
  16. Hi there, I have V700 with V200-18-E46B snap, I`m trying to figure out the connection to the analog input from 4-20ma sensor, The data of the v200 state that the maximum V in the analog input is 15, the sensor receives its V from the controller 24v, The output voltage from the sensor is 23. Volts .. Therefor I would assume there will be problem if I connect it to the input of the analog in (based on the maximum V in of the snap in 15v) Am i missing something here? do I need to provide lower voltage to the sensor? add something after the sensor to lower the volts? Help please. Thank you
  17. Hi, I'm having hard time displaying data on V700 PLC. After MODBUS config and reading holding registers HMI still shows 0. Do I need to write data to data table and only then display on HMI? Data has to be read from MIO 12-V I/O module. Network ID matches, start of vector links to hmi variable. What could be done or I did wrong? Thanks. I'm attaching vlp file here
  18. Hi there I was using remote operator for a new v700 install When I went to enter a value onscreen the remote operator was using a different keyboard layout to the PLC and so couldn't enter the value correctly Photos attached for reference taken of PLC and remote operator, any insight would be appreciated also I am using the latest Remote Operator 1.0.60.0
  19. Hello, Is there any place I can find CAD files for V700. I can't find them on the site.
  20. Hi, I trying to connect to V700-T20BJ via .net c sharp code, and the "GetPLC" function return "Unknown PLC Model" exception, I tried to debug and step into the function "GetPLC" and I saw that the code parsing the "PLCModels.xml" file, and I think that the code didn't find xml element that match the V700-T20BJ model. I attached the code here and the "Get OPLC information" from Vsio. Thanks ! Ethernet eth = new Ethernet("192.168.1.16", 20256, EthProtocol.TCP, 3, 3000); var plc = PLCFactory.GetPLC(eth, 0, "pita");//(eth, 0); Console.WriteLine(plc.Version.OPLCModel); Console.WriteLine(plc.PlcName); Console.WriteLine(eth.Connected); Console.WriteLine(plc.UnitId); Console.ReadLine();
  21. Hello, I am new in this forum and in unitronics, for this reason I have too many problems when I set up V700. I am following the manual "Using Ethernet" to V700 and I could not watch the IP address with I need to set up downloads throught the ethernet cable PC-PLC. When I try to simulate in visilogic anyprogram appears the next window "Run-time error 5 invalid procedure call or argument" I will start this topic with these questions. Thanks.
