  1. I think the best way to do this is to use the UniOPC Server (downloadable from Unitronics website) and an OPC Client which writes data to an SQL server. Google: "OPC Client" OPC Best regards, Don.
  2. Another thing to check is that the communication cable between the PLC and the EX-A2X is around the right way. One end of the cable should be marked "To PLC" and the other "To Adapter". Connect accordingly.
  3. Hello, We have a customer who loads a clone file of their project onto their V130s via an SD card. This is normally a quick and hastle-free process, without the need of bringing a laptop out. Recently, they had some trouble loading the clone file onto a new V130. After loading the clone file, the PLC displayed some random shapes (e.g., an elipse, a rectangle, etc.) and was unresponsive to keypad pressed (including holding (i) to enter information mode). I suspect the clone file had been created in a VisiLogic version prior to 9.xx and was being loaded onto a PLC with newer boot and/or binlib versions. This version incompatibility is mentioned on the Welcome Page of the Visilogic 9.xx help file: To avoid this problem in the future, I will suggest maintaining 2 clone files: one for PLCs with pre 9.xx software and one for PLCs with 9.xx software. From Information Mode on a V130, how do I determine which clone file should be loaded? How do I determine the BinLib version on the PLC from Information Mode? The 'SW Versions' display on a V130 shows: OS version, Boot version, Factory version and the PLC name, but no BinLib version. When I search the VisiLogic help file for BinLib, it only shows the reference to BinLib on the Welcome Page. How is binlib updated? The Visilogic System Upgrade Wizard only mentions installation of PLC BOOT and PLC O/S. Thanks guys. Best regards, Don.
  4. Hello, I would just like to check if there are any problems configuring a V570 to communicate on 2 separate Modbus RTU networks using PLC com ports 1 & 2 both using RS485? On one network the PLC would be a master and on the other a slave. Thanks. Best regards, Don.
  5. Are there plans to increase the size of the standard displays (e.g., the Alarm displays) on the large screen models such as the 1040 and 1210? We've had a couple of requests for this from people with large fingers. Don
  6. Hi toddster, I believe firmware changes were made to enable 16-bit (65536) color. The documentation for the V350-35-TA24 probably requires an update. "From VisiLogic 9 on, all images will be 64K colors (16-bit)" Source: http://www.unitronics.com/data/uploads/VisiLogic_Software_New/VisiLogic%209%202%200%20Version%20Changes.htm Best regards, Don.
  7. Hi v2comp,

    I would study the documentation for your proportional valves. The valves I have used have had a 'sealing function' or 'cutoff' parameter which would completely close the valve if the PLC's analog output fell below a threshold.

    I was controlling water. Gas is considerably more hazardous, so take care and consider employing the services of a qualified co...

  8. Yes, the IO-AO6X gives you 6 analog outputs, one of which could be used to control your proportional valve. An I/O expansion adapter (EX-A1, EX-A2X or EX-RC1) is needed to use the listed expansion modules. Glad we've been of help. Best regards, Don.
  9. How do you intend to control the position of the proportional gas valve? The v120-22-un2 does not have an analog output. Best regards, Don.
  10. Hi v2comp, The impression I get from your posts is that you would like for someone to write a complete program for you. If you are able to post specific questions in areas you are having difficulty, you will likely get a more useful and prompt reply. I have written and attached the beginnings of a sequence controller (created in VisiLogic 9.3.0). This may be enough to get you started. Your local Unitronics distributor may be of more assistance with this project. Hope that helps. Best regards, Don. Sequence Controller.vlp
  11. Hi Walkerok, The toggle option for Binary Text controls may be reserved for use on the 'Enhanced' divison of controllers. To see a list of Standard and Enhanced Vision controllers, search for 'Vision Controller Divisions' in the Visilogic help file. Best regards, Don.
  12. Hello, Is OPC data transmitted over GPRS secure, or is there a way of making it so? Is it possible to encrypt the data? Thanks, Don.
  13. Hello, Interesting that the problem disappeared after installing Chrome. I believe this message typically appears in Windows 7 or Vista if Visilogic is installed with Windows User Access Control (UAC) enabled. See this topic. Don.
  14. As a starting point, you could take a look at the FB Protocol example projects. Choose 'Examples...' from the Help menu in Visilogic and then drill down to the directory 'Version 900\Project examples\Communications\FB Protocol'. Don.
  15. Hi Dan, What are you doing with the produced CSV files? If you are opening them in Excel, Excel automatically drops leading zeroes (at least my 2003 version does). Don.
  16. Hello again, I successfully logged data to a Microsoft SQL Server 2008 Express Edition database using the trial edition of OPC Data Logger Pro available from: http://www.opclogger.com Note that I had to change my comptuters regional settings from "English (Australia)" to "English (United States)" to successfully log. Best regards, Don.
  17. Hi Sarnikorpi, I'd suggest using software to log OPC data from the PLC to a Microsoft SQL Server database. I haven't done it myself, but it appears suitable. I googled: +opc +"microsoft sql" One of many relevant search results was: http://www.opcdatalogger.com/ Hope that helps, Don.
  18. Hi Mizaro, You can find instructions in the help file if you search for "Fill Vector". I have attached an image showing example code. In this case, the whole database is zeroed upon a press of the Enter key. Best regards, Don.
