Indicator Lights (LEDs) and Terminal Board
The following figure shows how the indicator LEDs correspond to the circuit connection points on
an I/O Module's terminal board. The terminal board terminals are numbered from the top, with the
top terminal in the left row being number 1 and the top terminal in the right row being number 2.
The numbers alternate between rows with even numbers on the right and odd numbers on the left,
as shown in the circuit diagram on the back of the hinged cover.
