Sorry for rambling; i know I blurred my point. Basically I just want to replace a PLC with an arduino and I want somebody here to tell me that it's perfectly O.K. to do so....
25$ arduino should not be trusted to do the same job as a 2500$ PLC
Quote25$ arduino should not be trusted to do the same job as a 2500$ PLCNo chance there, the PLC costs that much for a reason.However that's not to say that you couldn't harden an Arduino to be suitable and come up with something at a price point somewhere in between.But in terms of getting that into a real industrial installation, no chance I would say, too many big boys have that market sown up.______Rob
I have also been playing around with the idea of using Arduino for PLC-like applications and my thoughts were applying it to small scale automation scenarios, or non-critical applications where a limb wont be lost.
