From flowchart to ladder

Tom Gardner · 2012-04-23T22:34:09+00:00

From flowchart to schematic to ladderI can design machine control circuits using relay logic but it's a grueling job for me. I don't do it often enough to be proficient. Typically, my circuits have 8 or less 344PDT relays with about as many switches and as many outputs like valve coils and such. I can do a flowchart in minutes but can't easily translate to a schematic.We only have a couple of PLC controlled machines. I did the flowcharts and hired a company to do the programming. I would very much like to become proficient at doing the whole job in house. I can think of a number of applications that using PLCs to replace relay boxes would be very beneficial.I use a bunch of stuff from "Automation Direct" and I've been looking at their "Click" line of PLCs. They seem inexpensive and powerful.So, how do I get from flowchart to Ladder programming?

One of those (other links, too) really shouldn't be too hard to re-write to a full RS274 version!

'Open Source', or for profit?

My priorities are new roofs for the shop & laundry building, and keeping up with repairs around the house for the foreseeable future. Things go to hell when you can't do anything for a couple years. :(
