number is also printed on the label on the side of the module. However, in order to see this
side label, the module has to be removed from the PLC
On the front side of the front cover insert are lines that correspond to the module's I/O points.
You can temporarily remove the insert and write the signal name for each point on the
appropriate line, as shown in the example in the figure.
Also on the front side of the front cover insert, running vertically on the left edge of the insert,
is a color bar that identifies the type of module: Blue = DC, Red = AC, and Gray = Analog.
Module Lens Cap. Located on the top front of the module, it covers the LED (Light Emitting
Diode) status lights . These are labeled in the following figure in two groups, A through A8,
and B through B8. Since this is a figure of a 6-Point Output module, there are 6 LED
status lights. (The number of status lights on any given module is a function of the number of
circuits points on that module.) If you compare these status lights to the connection diagram
on the back of the hinged cover, you will notice that the outputs on this module are in two
groups, labeled A -A8 and B -B8, that correspond to the A and B rows of status LEDs. Note
the additional LED on the right side of the lens cap that is labeled with the letter F. This is a
blown fuse indicator light. This letter F is present on all of the discrete I/O module lens caps,
but is only functional on certain Output Modules that have internal fuses. It only lights if an
internal fuse is blown. A table with a list of modules having fuses as well as other details
about the status LEDs is provided in Chapter 3 of this manual.
