1.2.5.2 ELC Series Digital Input/Output Extension Unit
The ELC controller automatically addresses discrete I/O based on the position of each I/O module
with respect to the controller. Independent of the number of discrete I/O points on the controller,,
the first Input on the first input module to the right of the controller will be X20. The first output on the
first output module to the right of the controller will be Y20.

Note:
Even though the second extension unit ELC-EX06NNNI only has 6 outputs, the other two output
addresses associated with it, Y26 and Y27 are invalid and should not be used.
1.2.5.3 ELC Series Analog Input/Output Extension Unit
The analog I/O modules are not included in the addressing associated with the discrete I/O modules.
The data sent to and read from analog modules by the controller is accomplished via TO and FROM
instructions used in the controller program. The addressing of discrete I/O modules completely
