Yeah i work with Kinetix 6000 servo drives we also have some ultra 3000 drives as well, We have Ethernet control logix L5000 series processors and we have the sercos comm. card interfacing the fiber optic loop. Pretty powerful stuff you can tune the servo from the plc, see the actual posistion, give various commands, see the current draw and reset faults and much more. Very easy to replace set the node address connect line, mtr leads, encoder cable, fiber optic and your done. Sercos Card is very easy to install slap it in the rack add it in the I/O configuration tree in RS5000 and thats it. We have packers that have multiple sevo axis on them. We have all are plcs networked together over ethernet and they send tags produced and consumed from plc to plc, we can acess the program anywhere over the server.All are remote I/O are on 1756 ethrernet IP cards and flex I/O modules, we have some plc 5s interface via DH Remote I/O on control logix rack as well. I believe eventually all conveyors. will be servo motors as they don't really require a gearbox they have tremendous amount of torque. We have Kuka robots at are plant as well and these things are servo driven no gearbox. And yes to answer your question it does impose problems. to many non qualified people make plc changes from the office and then they call us the electricians to figure out whats wrong. Its usually the plant engineers and the electrical supervisors who do this. I prefer to make program changes when i am standing in front of the machine wether it be on a server HMI or a wireless laptop so i could see how the process is being effected. I will work from the shop however when im working on panelview screens, pictures, alarms, not something that could effect the process or get someone hurt. And also on our conversion of 1305 drives to powerflex we had to make a few small plc program changes for some reason the powerflex wants to see the drive is running before you give it a stop command otherwise it was giving us nuisance faults.Thanks for your input guys
