The LYNX CM100 Control Module has a standard set of twelve +5 to +24VDC I/O lines and the LYNX
CM200 Combination Control Module has a standard set of six +5 to +24VDC I/O lines. These I/O lines may
be programmed individually as either general purpose or dedicated inputs or outputs, or collectively as a
group. The Isolated Digital I/O may be expanded to a maximum of twenty-four (24) lines on the CM100 and a
maximum of eighteen (18) lines on the CM200.
The I/O groups and lines are numbered in the following fashion:
Group 20 = Lines 21 - 26 (Standard CM100 and CM200)
Group 30 = Lines 31 - 36 (Standard CM100 only)
Group 40 = Lines 41 - 46 (Optional CM100 and CM200)
Group 50 = Lines 51 - 56 (Optional CM100 and CM200)
The isolated digital I/O may be defined as either active HIGH or active LOW. When the I/O is configured as
active HIGH, the level is +5 to +24 VDC and the state will be read as a “1”. If the level is 0 VDC then the
state will be read as “0”. Inversely if configured as active LOW, then the state of the I/O will be read as a “1”
when the level is LOW, and a “0” when the level is HIGH. The active HIGH/LOW state is configured by the
third parameter of the IOS variable, which is explained further on. The goal of this I/O configuration scheme
is to maximize compatibility between the LYNX and standard sensors and switches. The LYNX I/O scheme is
a powerful tool for machine and process control. Because of this power, a level of complexity in setup and
use is found that doesn’t exist in controllers with a less capable I/O set.

The isolated I/O may be utilized to receive input from external devices such as sensors, switches or PLC
outputs. When configured as outputs, devices such as relays, solenoids, LED’s and PLC inputs may be
controlled from the LYNX. Depending on the device connected, the input or output may be pulled-up to
either the internal +5VDC supply or an external +5 to +24VDC supply, or the I/O lines may be pulled-down to
ground. These features, combined with the programmability and robust construction of the LYNX I/O open
an endless vista of possible uses for the I/O in your application.
Each I/O line may be individually programmed to any one of 8 dedicated input functions, 7 dedicated output
functions, or as general purpose inputs or outputs. The I/O may be addressed individually, or as a group.
The active state of the line or group may also be set. All of these possible functions are accomplished with
of the IOS variable.
