Why aren't you using Layers? You can hide an entire layer while editing the HMI, so you won't have to send to back or bring to front.

I followed the instructions to make a factory reset SD card but the tool's standard software still launches. It does read that there is an SD card inserted with the software though. Not sure if there is a jumper or some other reset function I'm supposed to engage first.

Yep.  Subroutines are the way to go.  You're on the right track. Joe T.  

As Gabriel said - how is your input scaled?  Try linearizing the input over the voltage range you want.  This will linearize a 14bit analog input over the 0-1000 mV range you need - setting input voltage equal to bar essentially.  2v = 2bar, 10v =10 bar

Hi Joe, I appreciate the quick response. I'm particularly interested in thoughts about how I might adapt the general control strategy used for your customer's security gate to a smaller, more precise hydraulic mechanism like ours.  Any specific functions that your customer found particularly useful for managing hydraulic operations? I'm building the logic in a similar way I would approach an Allen Bradley program. Main Routine calls separate input output routines (I believe in another post you call inputs first and outputs last). So it's looking something like this: Inputs Conditions for operation, anti tie-down, and safety interlocks Cylinder Adv/Ret Timers Counters Faults Outputs   I hope this makes sense.
