I did a job several years ago where the consulting engineer for the town required us to install a SLC 5/04 at a water tank to read one 4-20mA signal (tank level) and one digital input (valve opened) and provide one digital output (close valve.) I argued for weeks to get them to let us quote and supply a MicroLogix at the site, but he insisted on the 5/04. More money for us on the project, but much higher replacement costs for the town in the event of a failure.
