Hey all, I need to adjust the time of a timer dependent on an MI bit, basically i need the timer to increase or decrease with a speed signal,
for example on average, it takes 20 seconds for 1 rotation of a drum on a piece of test equipment, but some operators prefer to run the tester faster and some slower so if the tester wants to run a slower test one drum rotation will take longer, and if the tester runs a faster test a drum rotation will take less time.
The test equipment only wants to do 1 rotation and its speed is determined by 0-10v signal to a DC speed controller hence the MI bit
i want to hit a start button and the timer automatically stop after one rotation, there is no facility for an input to determine one rotation as it never has a set start position.
Any help will be greatly appreciated
