I suspect I need to write a script to do this, but don't have any experience scripting in Vijeo. What I'd like to accomplish is to add an up arrow and down arrow, and enable the arrows to add and subtract from the speed setpoint that I entered in the numeric display. It pulls up a numeric display where I can enter a speed setpoint, and it works great. Any ideas how I can get this to display negative values? Second, I have again a numeric display that I enabled the input mode on, and it's looking at (%MW8602), also writing to it. I tried a couple other thing to do with displaying zeros, but nothing. I wasn't sure if integer was signed integer, so below zero may not have been valid, but float should have worked. I suspect it is because the values are negative. I'm using a numeric display and tried to use integer and float, but can't seem to get it to display either value in Reverse. I am displaying the Velocity (%MW8604) and Frequency (%MW3202) on my screen. The Magelis screen is connected to two Altivar 12 Variable frequency drives. I'm programming a Magelis HMSTU633 panel and have two things I'm having problems accomplishing.
I'm working with Vijeo designer 6.1 SP4, not sure that matters.
