Wow, that's bad...really bad...I didn't see that before...its supposed to the be e-stop and I didn't notice it amongst all the bushes the middle of a the two screenshots.
At least it's the only color on the pop-up, but he should really change the name and warning so as not to fool anyone into believe that it is where to run and press when some person is in danger...
A very forgevable mistake for someone who didn't crawl into PLC world from the relays through red wires controlling dangerous heavy machinery for years like many of us.
Yes, I would label it "SYTEM SHUTDOWN" and you can even have a pop-up that indicates that it indeed causes a safety PLC to open a relay, or whatever level of accurate information applies to what happens when it works...but don't get sued for an electrocution, or amputation, because you claimed it as and EMERGENCY STOP. If these are guarded fans and a few pumps and the worst thing that can happen is a ruined product then yeah, proclaiming the e-stop may be...craap, its still a terrible idea...and totally unnecessary. E-Stop on an HMI should only been seen as a status on an alarm list or as an indicator, not a fargin' big button People!
The Estop is a sacred God in industrial control reserved for a real button with real simple fall-off failsafe normally closed contacts with a mushroom headed maintained operator that is RED, with legend plate in YELLOW declaring itself the one and only GOD of the term E-STOP, and all other imitators of such god shall be stricken from existence if you are smart...in my humble okie opinion.
This Push Button, with a wires running through its contacts such that when pressed, a mechanical devices stops all dangerous motion and electrical energy from motors....This can't happen when the screen freezes, or the ethernet cable falls out...
I'm sorry for ranting, i had a chityy day at work....time for that Seagrams 7 and Diet Dr. Pepper and some local football news.
G'nite
