  1. Hello, 2D drawings are available for download on Unitronics website. https://unitronicsplc.com/unistream-series-unistream156/
  2. I'm now using load cell weighing transmitters with MODBUS TCP protocol made by LAUMAS and they work great with Unistream PLC's. The cost is lower than using the EX-RC1 and LC1, it is very easy to set up and all programming is kept within Unilogic. A dedicated load cell module is missing from Unistream's product range, we are waiting for it and hope to have it in the near future!
  3. Hi Aus, I will hopefully receive a COSY131 within the next few days. I will make some trials and then post my comments regarding the overall performance of the device and how it integrates with a Unistream PLC. Regards, Kikis
  4. Hi Guys, I have a customer asking to have remote access to the web server of a UniStream PLC via internet (everything works perfectly in the local network). I am thinking to use EWON COSY vpn router in order to achieve a secure connection. Is there anyone who used this device before? What about connection reliability and response speed? Do you know of any other similar product which can be used for such an application? Thanks and Regards, Kikis
  5. Thanks Aus and Kratmel for your replies. Yeah, that's exactly what i was thinking as a solution.
  6. Hi Guys, Today i made a travel of 60km to check a problem on a JAZZ PLC after getting a phone call from the customer. From his descriprion during the phone call, it was clear that O1 (relay output) was worn out, and it was indeed. So i downloaded a new program to replace O1 with O5 which was not used and installed an RC snubber accross the driven AC coil. What is the best and easiest way, in terms of programming, so that the customer would be able to replace inputs and outputs from the HMI screen?
  7. @Cara Bereck Levy Btw for such applications which require X-Y servo positioning, it would be great to have a special PTO function block to perform synchronized linear motion using the 2 axes (Linear interpolation).
  8. Hello, I'm attaching an example i made based on your description. I have set the timers for FWD and REV direction spinning to 3min, but of course you can set the values as you want. EXAMPLE_1.vlp
  9. There is no doubt that it's a matter of sales and money. Since all major manufacturers of "smart programmable relays" or mini PLC's have 100-230VAC models available (Schneider Zelio, Omron Zen, Siemens Logo), i suppose that there is true demand for small controllers with such specs.
  10. There is equipment and machinery powered by 3 phase -3 wire 415V (Neutral is not used), such as industrial water chillers and air compressors. Manufacturers usually use a transformer to get 230V secondary output and use it as the control system's voltage. Sometimes is not straightforward to switch from an existing 230VAC control system to a 24VDC PLC unit, it requires a lot of wiring changes and extra cost.
  11. Hi Guys, I was recently working on a small project to replace a Zelio programmable relay with a Jazz PLC. Zelio's power supply and inputs were 230VAC, so i had to install a 24VDC power supply to feed the Jazz and the inputs (limit switches, push buttons, etc.) In addition, i had to replace two 230VAC magnetic sensors attached on a pneumatic cylinder with 24VDC sensors. I was thinking that It would be great if we had some JAZZ models available with AC power supply and inputs (100-240V).
  12. Hi Sunit, Great work! I have successfully completed a similar project in the past. I'm using CAM software to extract X-Y hole center coordinates from the CAD file which i store in a data table for positioning. Could you please share how did you manage to transfer AUTOCAD DWG files to V130?
  13. No, there is no offline simulator in Visilogic software. In order to run your program, you need to be connected to a PLC.
