Hi guys, I have now tried starting a new project. Absolutely no ladder at all. I have still got the analog outputs directly wired to the analog inputs. Output 0 to input 0, and output 1 to input 1. I have scaled both inputs and outputs in the I/O settings to have a range from 0 to 10000, they are also both set to 0-10v. I created a watch table for all 4 (analog input 0 and 1, and analog output 0 and 1). If i understand correctly, if i send analog output 0 to a value of 1000 i should get 1000 back on the input? This is not the case i appear to get a value of 340 on the input. How can this be possible? The scaling is the same and one is directly connected to the other. I have checked the voltage and that appears to be correct just not the value of the input. -
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
