Hi Guys, I have a project to upgrade a machine from an old V280 PLC (installed back in 2007) to a new V700 model. Is it possible to use the existing EX-A1 exp. adapter with a new V700 PLC or do I have to replace it with EX-A2X? BR, KIKIS

Hi Guys, I will use a Unistream PLC to retrofit a pressure testing machine. The system needs to generate a PDF report after the completion of every test. The report must include the start and end date-time of the test, datalog of pressure value, trend graph of pressure vs time and the final result of the test (pass or fail). What is the best way to do this? Anyone has made a similar project in the past? It is straightforward to put all this information on the screen, but how to include it in a PDF report? Best Regards, Kikis

Hello, Open font handler by clicking the (A) icon on the toolbar, from there you can add a new font.

Hello Ricardo, A good and safe way to have internet remote access via Webserver or VNC is to use a VPN router with integrated cloud service. There are various options available such as Ewon, Tosibox and MBconnectLine products.

Hello, If i'm not mistaken, .ulri files are used to import HW configuration into Unilogic (Unistream platform) to establish UniCAN communication. Regarding Visilogic HW configuration, it should't take more than a minute to set it up. For samba models is just a matter of 1 click, since there are no expansion modules. If you need to import operand descriptions from an existing visilogic project into a new one, you have this option (Edit - Import/Export operand descriptions).

Hello, ATV320 comes with only a serial port as standard, if you want to use Modbus TCP you need to add VW3A3616 Ethernet module. BR, KIKIS

Hi, I think it's better to create a jpg image with all static icons/symbols and use it as background on that page. Then add all binary/list elements and other variables above the background image. Best Regards, Kikis

Hello, There are vision models with no temp. sensor inside. I always use a panel mount cooling fan and a DIN rail type thermostat for switching on/off the fan. Never had problems with this configuration, even during hot summer months in which ambient temperature exceeds 40 degrees Celcius. Best Regards, Kikis

Hello, I bought a new laptop a few days ago and had the same problem for both U90 and Visilogic. I restarted my PC after installation and problem was solved for both software! Best Regards, Kikis

Hi Mia, Have a look on this topic, it might be helpful.

Hi Joe, Thanks for posting your thoughts, sharing your experience is always valuable for us! Regarding the Unit Price for Ewon Cosy, my comment was from customer's point of view.I have a lot of customers asking to have internet remote access, but once they hear the cost, they finally decide that they don't need it! BR, KIKIS

Just a few comments regarding the Ewon Cosy VPN router and its integration with Unistream controllers. I have used the Cosy to remotely connect to a Unistream 10.4" HMI via VNC through internet and it works great. I also used the NAT 1:1 function, so that the user won't need to use internet when connected in the same LAN. Connection is 100% reliable and response is relatively quick, there is a bit of lag but it is fairly acceptable. It takes approx. 15 min to set it up and get it working, only very basic networking knowledge needed. Connection is achieved via Ewon's M2WEB cloud service and requires to have a valid TALK2M account. Unit price for a COSY 131 is quite high (490 Euro), but in my opinion it is worth as connection security is number 1 priority.

Hello, 2D drawings are available for download on Unitronics website (https://unitronicsplc.com/unistream-series-unistream156/)

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!

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

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

Thanks Aus and Kratmel for your replies. Yeah, that's exactly what i was thinking as a solution.

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?

@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).

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

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.

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.

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).
