  4. Crouzet Millenium 3

    NFAGEN posted a topic in Other PLCs

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?

  7. NX1P2 FTP Data Sending Process

    man31 posted a topic in Omron

    Hello people! I'm working on a project that part of it, is to send data that are collected in the PLC, via email to office. The PLC and HMI I use (NX1P2 and NB series),they do not support any email instruction, unfortunately.  To overcome this obstacle, I decided to forward those data (saved in .csv file) by using the FTPPutFile instruction and to upload the csv file from PLC to a dedicated folder to the office computer. PLC will be the client (passive) and the computer will be the server. And here is where I need your help.. The set up is offline by using a dummy ethernet switch. I set an IP address in the computer, as well as to the PLC side. If I set the PLC as a server (FTP server ->use -> port 21,pass & username), I can connect from the office computer to the PLC and download the file, by using cmd. When I try to use PLC as a client, Ftpputfile instruction always gives errorid 2407 and erroridex 00000226. In the FTPPutFile instruction box I set the following: ConnectSvr: IP address of PC, port 21, username & pass  SvrDirName: the physical path I set when I configured the FTP site on PC (C:\...) LocalDirName: '/' FileName: '.. .csv'    Further more, in the file explorer I type ftp:\\(IP address of PC), I log in but when I try to create a new folder 550 error is coming up (I suppose this is for permissions). Am I missing something? Do you have any suggestions/guide for making this work? I am not an IT and I am not experienced in that field so any help would be great!   Thanks! Man31          
  8.   Hello, I downloaded the program from the M251 PLC program, using the SoMachine4.3 environment. However, the downloaded program does not compile because the library is missing. The library is from a different manufacturer. Is it possible to find this library on the M251 PLC device? is there any way?
  9. Hi All, Has anyone had the experience of connecting two Fernhill Scada units using an OPC UA?  I am intending to use Fernhill Scada on my Master PLC to read tags from my Slave PLC's Fernhill Scada. Then, displaying local tags (Master PLC, "Fernhill SCADA Unit 1") and read/scanned tags from the Slave PLC, "Fernhill SCADA Unit 2". In the meantime, I am trying to use both of my Fernhill SCADA units interact with each other (one unit to read tags from the other unit) by using Internal Digital Tag on the Fernhill SCADAs.  Any help would be appreciated.

  14. Hello everyone,  I have a Panelview plus 600 ( I know it’s old but I’m trying to get it to work). It’s on a yogurt bucket filler, I don't have any application to run or to do anything. What software do I need on a computer to be able to transfer it to the panelview. Is this even possible?  There is nothing in the memory right now but how to I program it and what program do I use?  I’m in the Los Angeles area and even willing to pay for someone to come and do it.  I need to get this to work, thank you so much. 

  15. WonderWare Help

    GarrettWrightsmanAIS posted a topic in HMI & SCADA

    Hi all, looking for some help. Have been using WonderWare since version 7.1. We currently use WonderWare 2020, but some of our products still require 2014 R2. Here lately, I have had trouble installing WonderWare 2014 R2 on Windows 10, specifically the SQL 2014 install. I have attached an image of the error message. I have tried multiple different methods to resolve the issue including pre-installing different versions of SQL Server. Thanks all!

  16. Serial communication with KINCO PLC

    Francisco1998 posted a topic in Other PLCs

    Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.

  18. I am using Factory talk view to practice but there is not any physical HMI ,I have been come up with errors.  So,I am not sure to create new HMI server ,it requires physical HMI?? THANKS
  19. Here is a step by step tutorial... Utilizing the CX Server DDE Manager will allow us to provide a link to the information in the Omron PLC. This link can be placed on an Excel spreadsheet. Charts, graphs, etc. can be made from the data. We will create links on an excel spread sheet from a CQM1H and a CP1L PLC. The information will then be displayed as a bar graph comparing the first ten memory areas. Here is a step by step tutorial... Watch on YouTube : Implementing the Omron CX Server DDE and Excel Let me know what you think. Regards, Garry
  20. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  21. Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)

  22. Unconverted Ladder Code?

    berkotropia posted a topic in Mitsubishi

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks
  23. I have an analog output card 1734-OE2V and there is in the fault/actions page parameters for program mode. What is program mode and when it is activated? Fault mode is clear but... Program should be written the value, but when this happens?
  24. Hello I have a M251, running a webvisu. I have created a program to create a test report to a *csv file and store it on sd card. What I want to do next is to allow the user to download the * csv from the webvisu and not via ftp client like Filezilla. On codesys forums I see there are file up and download options for buttons (click behaviour) but they are not available in Somachine 4.3. One option I am considering is using the TCP server and steam the file manually from a button click. I dont want a ftp client as now the customer will then needsoftware on his pc, this plc is a portable test system and will be controlled by many different pc's. Is anyone aware of a simpler way to do this?
