From flowchart to ladder
From flowchart to schematic to ladder
I 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? |
