[PSUBS-MAILIST] Touch Screens & PLCs

Mon Oct 6 17:14:55 EDT 2014

Thanks Hugh,having the right nomenclature has brought up a lot more options in the search.I like my idea of scrolling screens off buttons on the motor control joy sticks &may have to add that function to a touch screen as most HMI interfaces aretouch screens.Alan

Subject: Re: [PSUBS-MAILIST] Touch Screens & PLCs  Some additional comments to my previous post are that I amfinding it hard locating a small touch screen for use in harsh environments &don't  necessarily need a touch screen, as it may be better to have scroll & function buttons operating either off my motor control joy sticks, or nearby.So these scroll / function buttons would be wired in to the PLC first.Alan

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-T4CLIt 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
