1 Initialize hardware components
o
Initialize SLC backplane driver
o
Test and clear all RAM
o
Initialize the serial communication ports
2 Read configuration for module from IEC103M.CFG file on Compact Flash
Disk
3 Initialize the databases and ports
4 Set up the serial communication interface for the debug/configuration port
After the module has received the configuration, the module will begin receiving
and transmitting messages with devices on the serial networks.

Upon completing the power up configuration process, the module enters an
infinite loop that performs the following functions:
3.1.3 SLC Processor Not in Run
Whenever the module detects that the processor has gone out of the Run mode
(that is, Fault or PGM), the protocol ports can be shut down as prescribed in the
user configuration. When the processor is returned to a running state, the module
will resume communications on the network.
