[PSUBS-MAILIST] Touch Screens & PLCs

[Alan James via Personal_Submersibles]

HiI'm looking at my touch screen & PLC options & I'm a bit clueless here.I want  to display about 50 inputs. (I note that Cliff's R300 system displays about 60.)Also I'm looking at using a life support system similar to a rebreather as per JamesCameron, & this will need to have outputs from the PLC & a screen display.I am wanting to go reasonably small with the screen size & have been looking at the4" C-more touch screen.http://www.automationdirect.com/adc/Shopping/Catalog/Operator_Interfaces/C-more_Micro-Graphic_Panels/4_inch_Panels_-a-_Accessories/EA1-T4CL
It may be an option to use 2 of these screens as there are certain functions that I want displayedcontinuously. There seem to be a lot of pluses with the C-more system as it is easy toconfigure the screen & alarm set points, however the graphics look a bit basic.They do state that it supports user generated graphics so it may be easy to create my ownwhere necessary.Are there any other good options out there? Or am I heading in the right direction?Regards Alan
