The Toshiba hardware is outstanding. The software developers should take lessons from AB.
Still the software is user friendly in my opinion.

But then, my wife went on vacation on 8/4/07, and never came back. But that could be a whole (deleted) thread in itself!
Then there's my neighbor across the street.....Mike Johnson. Oh, nevermind!
Mickey said:Is that went on vacation or going on vacation or something you are hoping for?

8nman said:This is probably common knowledge to this group, but I am new here. . . Our Allen Bradley Micrologix keeps losing contacts. It was hard for me to believe the still used mechanical contacts in a PLC. Anyway, it dosen't make them user friedly in my book. I liked the old fashioned smokin' triacs.

OkiePC said:There are still lots of things that a PLC can control that require dry contacts.
As for you Micrologix, there is a good chance you need some surge protection on those outputs if they keep dying. Are you by chance running solenoid valves with them? Or motor starter coils? Interposing relays and/or surge suppressors will probably help out.
8nman said:True that some functions require dry contacts, but the Micrologix architecture gives you no choice. Daisy chaining dry contact relays in line with dry contact outputs seems redundant. Oh well . . . it is probably the reason they are inexpensive.

Mickey said:The ML series DOES have triacs and FETs. Which ML do you have 1000,1100,1200 or 1500. I will post the spec for you.
