At present we have AB SLC's controlling and monitoring processes in a wastewater plant. New motorized valve actuators are to be installed replacing older equipment. Some of the connection wiring is faulty, as is the underground conduit. It will be much simpler and less expensive to replace all of the control wiring with a data cable, right? My question is which protocol will be best for this application.
Control cards are available for both protocols from the actuator manufacture. It seems to me that Allen Bradley is pushing the DeviceNet connection, while I have been told that the Profibus will work and be less costly. Between the two, does one take up anymore overhead than the other in the SLC processor? Any other pitfalls I need to know about?
Thanks
