Status LEDs and I/O Points
The illustration below shows the relationship between the status LEDs on a
module and the module inputs or outputs.
In general, an I/O module's status LEDs appear over their associated
terminals. In cases where two I/O points are terminated in the same column
(for 4 and
1
6 point modules), the LED's relative position (top or bottom)
indicates the I/O point it is associated with.
For a single-width module with 4 inputs or outputs (middle module in the
illustration above), the LEDs and terminal points are associated as follows:
LED
1
Terminal point
1
.
1
LED 2
Terminal point 2.

LED
3
Terminal
point

.4
LED 4
Terminal point 2.4
On the four-slot module, LED 2 on slot 4 is indicated. The LED belongs to
input
1
4 on terminal point 4/2.
