INTRODUCTION
This section explains the front panel indicators and start-up
procedures for the IMDSI1
digital input module.
INDICATORS
The DSI module has point (input) status LED indicators on the
front panel to aid in system test and diagnosis. There are 16
LEDs divided into two groups of eight (group A and group B).
The location of the LEDs is shown in Figure
. Each indicator
represents a digital input. A red LED indicates an energized
input. A blank LED indicates a non-energized input.
START-UP PROCEDURES
The control module controls the start-up of the DSI module; it
is fully automatic. Function Code (FC) 84 in the control mod-
ule configuration enables the DSI. Specification S1 of FC 84 is
the I/O module address. It must be the same as the address set
on the address dipswitch (S1).
