Hi Stanley,
I'm an electrician at a large OSB (orientated strand board) factory in northern Minnesota. This factory originally used mostly Square D and TI PLCs (circa 1980), but all but one TI system have been replaced now with Allen Bradley PLC-5/30 and 60 series processors using ICOM software. We will be converting over to RSview soon. Operators control using panelview touch screens, and windows NT/2000 based PCs using controlview.
We also have many Allen Bradley frequency drives throughout the plant. Every processor, freq drive, and programming node is linked together via data highway. The processors message one another throughout the process via this data highway. All of this new technology is tough for an old geezer like me to learn!
