Because its plc controlled you could do this.
Keep in mind it would require A LOT of programming but it is doable.
Once you figure out what the ideal setup is for the amount of lead and the cool down timers (lead and mold) then you could have a sub-program for each of the calibers you cast.
You then have a virtual switch for each caliber.
The switch would then run that set of timers.
To my limited knowledge, I don't think you can do a look up table with the PLC.
The touchscreen doesn't store any data beside its own programming.
In fact you have the option of the touchscreen storing the ENTIRE program so you can retrieve it later (touchscreen program) or have it so it can't be read out of the touchscreen.
I load for 14 different calibers but it ends up being only like 12 different molds.
I could have 12 different screens on the touch screen that I can change each timer for each mold.
Then I could have a screen to select the mold I am using which would then active that mold's program.
The only limitation to what you can do on a PLC is the size of the program and covering all the points (inputs and outputs)
I ran into a snag last night.
All versions of the Hatch program are incompatible with the touchscreen.
This has to do with the fact that I used a fixed data entry instead of a dynamic.
Correcting this issue is pretty easy and only took about 5 mins to fix.
I haven't tested it yet but it should work from what tech support said.. Yes I had to ask for help.
