5.2.1 General Concepts
The following topics describe several concepts that are important for
understanding the operation of the MVI69-101S module.
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 Reads configuration from Compact Flash Disk
3 Initialize Module Register space
4 Enable Slave Driver on selected ports
After the module has received the Module Configuration, the module will begin
communicating with other nodes on the network, depending on the configuration.
