DIAGNOSTICS

The typical procedure is to select a diagnostic test to execute,
set the module dipswitches accordingly, reset the module, and
observe the results on LEDs one through eight. The selected
test executes repeatedly until the MFP module is reset and
another test is selected.
Some tests may require an additional module (an IMDSM05 I/
O module for the expander bus communication tests; an addi-
tional NTMP01, NIMP01, or NIMP02 termination device for the
redundancy link and DCS link tests). Refer to Tables
for the IMDSM05 I/O module configuration required for
the I/O expander bus communication tests.
Dipswitch Selection
Set pole one of MFP dipswitch SW3 to one (open position) to
put the module into the diagnostic mode. In diagnostic mode
use the remaining poles to select module address and bus
mode. Dipswitch SW4 selects the diagnostic test to be executed
and how it will be executed. Figure
defines the function of
each position of dipswitches SW3 and SW4.
Pole one of dipswitch SW4 selects the LED display mode. The
pass/fail display mode uses LEDs one through eight to display
a combination of incrementing pass and fail counters. LEDs
one through four indicate the number of passes successfully
completed and LEDs five through eight indicate the number of
failures. The test number display mode uses LEDs one through
six to display the diagnostic test number and LED eight to dis-
play whether the test passed or failed. If a diagnostic test is
successful, LEDs one through six display the diagnostic test
number and LED eight does not illuminate. If a diagnostic test
is not successful, LEDs one through six still display the
