Hi all!
I am a graduate student-lurker in this list. I am working on a college lab automation project, where I need to control some processes
using a PLC, and web-enable them.
Could someone recommend/rate current industry standard PLCs in terms of their linux friendliness? Which PLC lines have the best open
source s/w available for linux. I will be in a position to hack/add on to such software, but would rather go for whichever PLC already supports linux best.
Procurement will be easier for me if I stick to known brands (here in India) like Allen Bradley,Modicon/Schneider , GE-Fanuc etc
--Ideally, I'd like to program, monitor and if possible even write to the PLCs registers. Is it possible? Can I directly intervene to set PLC
outputs through a PC? Can I re-program a PLC on the fly using a PC?
--A decision that I have to make is whether to look for simple RS232 for communication..in which case I do not need to much supporting s/w as
RS232 libraries are easily found/developed, or to go for Ethernet which will make web-enabling easier.What about MODBUS or any other open
standard..any libraries out there?
Any advice/comments are welcome. I hope this question is not too off topic for this list.
thanks for your time
Gaurav
P.S. If anyone is interested, I have a small oscilloscope like program running comedi and GTK+ on a linux box, which we use for general purpose DAQ and display, I'll be happy to make the source available to anyone who needs it. No GUIs and stuff..code only
