INTRODUCTION
This section explains the front panel indicators and start-up
procedures for the Digital Slave Module (IMDSM05).
OPERATOR/INTERFACE
The DSM module has point (input/output) status LED indica-
tors on the front panel to aid in system test and diagnosis.
There are sixteen 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 I/O circuit. A red LED
indicates an energized I/O point. A blank LED indicates a
non-energized I/O point.
START-UP
The DSM start-up is fully automatic. The master module con-
trols the start-up. Function Code (FC) 84 in the configuration of
the master module enables the DSM. The address in FC 84 spec-
ification 1 must be the same as the address set on the address
dipswitch. The front panel LEDs should verify the start-up of the
slave (a voltage input must be present to light an LED).
