Do Allen Bradley PLCs share a common cable as far as programming cable is concerned? What I mean is when you are writing up the program you do it mostly from the PCs (Win2000)? and then you upload it to the PLC, right? If so did Allen Bradley keep the same cable format from one PLC series to another? or do they change the construction of the cable, and make people buy a different cable for each series of PLC? Do the 177x,174x, Micrologix, SLC etc use the same cable? Are they expensive to get?
Suppose you managed to buy the PLCs and the cable, do you need anything else to start learning the thing?
