Functional Overview
5.2.1 General Concepts
The following discussion explains several concepts that are important for
understanding module operation.
Module Power Up
On power up the module begins performing the following logical functions:
1 Initialize hardware components
o
Initialize CompactLogix or MicroLogix backplane driver
o
Test and Clear all RAM
o
Initialize the serial communication ports
2 Module configuration
3 Initialize Module Register space
After this initialization procedure is complete, the module will begin
communicating with other devices on the network, depending on the
configuration.
Main Logic Loop
Upon completing the power up configuration process, the module enters an
infinite loop that performs the following functions:
