Raul95 Posted August 27, 2022 Report Share Posted August 27, 2022 Hello, I am looking to use Unistream 7'' (Combined Plc & Hmi) + USC-P-B10 UNISTREAM CPU + 2x UN-UIA-0006 , as for my project, I would like to control the speed of 10 motors which are driven by individual inverters on voltage from 0 to 5V. So the 2x UN-UIA-0006 Analogue output modules would give me the number of analogue outputs that I need. The stop and start of the motors are controlled from a different control unit, so I am hoping to be able to adjust the speed only of all motors from the same screen. I am looking for some guidance as I have absolutely no experience with Plc's. I did download the software but I do not really know where should I start. Thank you, Raul Quote Link to comment Share on other sites More sharing options...
ORSO2001 Posted August 28, 2022 Report Share Posted August 28, 2022 hi Paul, you can download the examples projects from the same page where you download the software...those projects will help you a lot to understand how the unilogic software unilogic modules works Quote Link to comment Share on other sites More sharing options...
Raul95 Posted August 29, 2022 Author Report Share Posted August 29, 2022 HI ORSO2001, I did downloaded the examples projects but it won't let me open them, as it comes up with an error ''read only''. I did managed to figure out the hardware configuration and to create the HMI screen, but I am not sure what tools to use for the ladder programming, as I do not have any inputs. I know that I have to use linearize tool for converting the numbers to a percentage, but I do not quite know what other tools I need to allow me to change the percentage of an analogue output from the screen. Thank you, Raul Quote Link to comment Share on other sites More sharing options...

Hello again, I did managed to look trough some projects but none of them have any analog output, I did some research and I noticed that in other software there is used SCALE_ X "Scale" and NORM_X "Normalize" in ladder for output analog. In unilogic software I can not see any of them tools, could you please tell me which tool I should be using instead ? Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted August 30, 2022 Report Share Posted August 30, 2022 There´s a function called Linearize, take a look at it (ladder toolbox under math section). That´s what you need. Quote Link to comment Share on other sites More sharing options...
ORSO2001 Posted August 30, 2022 Report Share Posted August 30, 2022 hi Raul, take a look at this link: https://www.unitronicsplc.com/Download/SoftwareHelp/UniLogic_Knowledgebase/Ladder/Ladder_Elements/LF_Math_Elements/LF_Linearize.htm Quote Link to comment Share on other sites More sharing options...
Raul95 Posted August 31, 2022 Author Report Share Posted August 31, 2022 Is it possible to simulate the program without connecting it physically to the plc ? Thank you everyone for the help, I really appreciate it. Quote Link to comment Share on other sites More sharing options...

No it's not. However, you'll find that purchasing a PLC to use for this purpose likely will be cheaper than the software simulator that you might buy from other PLC manufacturers. You do NOT need to purchase any I/O, as the PLC is designed to run in simulator mode without any I/O attached. Quote Link to comment Share on other sites More sharing options...

Actually, you can linearize right in the analog I/O setup. No need for the Linearization function block. The analog output will be 0-10V, so just enter 0 for 0V and 2x the speed for 5V for the 10V entry. Quote Link to comment Share on other sites More sharing options...
