spotter90 Posted August 27, 2019 Report Share Posted August 27, 2019 I'm trying to use the accelerate FB in Visilogic, using a V430-J-TR34. I wanted to write a very simple program to make sure I can use this correctly, and I can't get it to work. Can anybody help me to figure out why this program doesn't work? I want to increment/accelerate MI 0 while the button on my HMI is pressed. If the button is released, the value should stop changing. Pressing the reset button will reset its value back to 1. I'm scratching my head as to what I'm doing wrong here... Accelerate Test.vlp Quote Link to comment Share on other sites More sharing options...
AlexUT Posted August 28, 2019 Report Share Posted August 28, 2019 Spotter90, What VisiLogic version do you use? Attempt to check for OS update from Help menu, then update PLC OS with new one and test again. If this does not helps - send your request to support@unitronics.com B.R. 2 Quote Link to comment Share on other sites More sharing options...
spotter90 Posted August 28, 2019 Author Report Share Posted August 28, 2019 My Problem was solved by AlexUT and support. I was running the latest version, but had to update the PLC OS. From support: Which version of software are you working with? Please ensure you are using 9.8.80, and then go to Help > Check for updates > Operating System. Then please update the controller of the OS. There was an issue with the acceleration function block in previous versions. Thank you for the help!
