I have been able to get my project working somewhat and I have attached the latest ladder. With this setup I am able to get the counters to increment but it seems I am only getting about 10 percent of the pulses to register, With a ppr of 13 and rpm of 6000 I should be seeing 1300 pulses per second. If I spin the shaft by hand i do indeed get the exact amount of pulses I would expect. I have a gear bow with a 12.7:1 ratio . 1 revolution by hand at the driven end gives me 166 pulses. 13 ppr x 12.7 ratio = 166 pulses per rev If anyone has info regarding how to set up the high speed inputs this may be where I am messing up It seems like I may only be getting counts based upon the scan rate and not the HSC I am trying to use. Any though would be greatly appreciated, Chair lift project.ulpr

I am trying to get a couple of encoders working on a new project. I have attached my program for review. I have done similar in U90 ladder with success but this is my first try in unilogics. My controller is a US5 B10 T42 The encoders are magnetic and have 13 ppr. and the motor speed is 6000 rpm I have tried unsuccessfully to change i0 and i1 to high speed I am not sure what I am missing here except that I assume the encoder is way too fast for the plc to count each pulse, Also I am confused as to why the INC command seems to increase not in time with the encode pulses but with the time that it is enables. The ultimate goal once I get this figured out is to use the encoders to ensure that they stay synchronized as the actuators move up and down Chair lift project.ulpr

I have written a project for a Unitronics US5-B10-T42 PLC. I have been able to get all of my features to work except for 1 very simple item that should be a no brainer. I have a counter that is supposed to keep track of all cycles for the history of the machine. I have attached the details below. Even though I have checked the "retain" box each time power is removed the counter resets. Please note as well that I was also getting a RTC error each time I connected to this plc until I did some troubleshooting and found that the battery was dead in this brand new PLC. Once I changed to a new battery the RTC error disappeared but my counter still will not "retain" its value Any help will be greatly appreciated
