Chapter 5 Choosing a Device for a Remote Station
Choose a Device
Choose from a variety of remote stations that fit your application and cost
requirements. The most cost-effective remote station for applications that use
limited analog and/or discrete I/O are the Micro800 and MicroLogix families of
programmable controllers. Otherwise, choose an SLC 500 or CompactLogix
system for your remote station, unless specific redundancy, I/O, environmental,
or communication requirements are only met by a ControlLogix or DataSite
RTU system.
