Hello friends, I am new to Unitronics hardware and have about 1 year experience with ladder logic (studio 5000 up to this point). I am tasked with writing a program for a machine that uses the following components and I just need some help on choosing the right Unitronics PLC and what snap-in's I will need to work with the components: -conveyer belts (1 requires indexing/location tracking) -motor driving an actuator -motor moving a tray back and forth along rails -9 load cells I am leaning towards the Vision 350 TR20 currently, and it looks like the IO-LC3 modu
Machine has 4 load cells (30klb each, 2mV/V) into a Summing Box, then the single output from the summing box going into LC2 on an I/O LC3. The Load Cells are measuring clamping force of a bolted joint and, as such, there is no real way to put a reasonable known weight onto the LC's and hit "Calibrate." Eventually we'll have a calibrator come out with a through-hole Load Cell to dial it in, but we need to get it in the ballpark to get started. In this application, relative values are more critical than accuracy so if we're off 5% no big deal. I used some simple math to determine that
