I work for a firm that’s tied down to just a couple of older PLC types. Looking to the future I’m wondering what features particular brands have that are very useful that others don’t do. We’re likely to be looking at the bigger suppliers, RA, Siemens, Schneider, Mitsubishi etc...
Reading similar questions on here I’ve come to the conclusion that the hardware is fairly comparable between them all. I noted that Contrologix can do hot card swaps, and Schneider don’t have backup batteries. I don’t know much about Siemens really.
I suppose it’s a bit like a dream team I’m trying to build. What features could you draw from all brands to make the ultimate offering? I want to work out what is useful from a specification point of view.
It’s a slow moving process we control. Analogue and digital I/O - no motion control, very little intelligent instrumentation and drives (we’ve been using profibus for this where we have it)....
Thanks for any input
Andy
