  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. dont know why it double posted, the other is a Koganei KFP050-2-30-FM-BR-02

    High-precision Proportional Control Valve has been newly developed, which is optimum for the production lines, plants, etc of air, gas, liquid, etc. The stepless control is realized, which is necessary to control the flow rate of gas and liquid. Standard input signal can be selected from 4 to 20mA in current as wel...

  11. I guess the Moderators dont want other equipment manufacturers product specifics listed on the forum, I guess I should have read that somewhere, but anyway, the two different proportional gas valves and controllers I have are:

    1 ASCO 8202 posiflow 24vdc and its controller

    2-Way, Direct Acting, Brass or Stainless Steel Bodies, 1/8" to 3/8" NPT.

    Flow rates adjustable...

  13. thanks for responding to my posts, I have responded and am waiting on the MOD to post them. I really appreciate your helping me, thanks again.

  14. 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.
  15. 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
