Internal Architecture and Processing Power

This processor module uses a 16-bit CPU for logic execution. A quartz oscillator provides precise timing for all operations. The ABB 3BSE000270R1 stores user programs in 64 KB of static RAM. A replaceable lithium battery maintains this memory during power outages. The processor executes bit operations in approximately 0.6 milliseconds per kilobyte. Consequently, this module handles medium-sized applications reliably.

Installation and Programming Guide

First, insert this processor module into the designated slot of your S100 rack. Next, connect your programming device to the 9-pin RS232 port. Then, upload your application using ABB programming software. The module supports ladder diagram and function block languages. You can expand I/O by adding S100 remote racks via ribbon cable. This processor module communicates with I/O modules through the backplane bus. Four LED indicators show power, run, stop, and fault status. Always replace the lithium battery when the low voltage warning appears. Remove the module from the rack before changing the battery for safety.
