DIAGNOSTICS
The IMMFP12 Multi-Function Processor Module firmware con-
tains diagnostic tests that can be invoked during module
power-up. Putting the MFP module into the diagnostic mode
allows the module to perform a variety of diagnostic tests but
suspends normal operation. The diagnostic tests allow verifica-
tion of the module components and circuitry. This section
describes each diagnostic test and how to use it.
Overview
Select the required diagnostic test using the MFP module
dipswitches. LEDs one through eight display the results of the
test. Both group and individual tests can be executed.
