CLT = 0 Command the SmartStix I/O Module to set its Life Expectancy Time to 2.0 seconds, as the maximum
time to wait between Control Station to SmartStix I/O Module output control data messages, before
setting all Digital Outputs to their default states.
CLT = 1
Command the SmartStix I/O Module to use Word 4’s Life Expectancy Time. In this case, a value of 0.0
disables the Life Expectancy feature.
CHT = 0
Command the SmartStix I/O Module to set its Heartbeat Send Time to 1.0 second, as the minimum time
between SmartStix I/O Module to Control Station Heartbeat messages.
CHT = 1
Command the SmartStix I/O Module to use Word 4’s Heartbeat Send Time. In this case, a value of 0.0
disables the Heartbeat Send feature.
CIT = 0
Command the SmartStix I/O Module to send its Digital Input data to the Control Station, only when the
Digital Inputs change state.
CIT = 1
Command the SmartStix I/O Module to use Word 4’s Digital Input Send Time, to determine how often to
periodically send its Digital Input data to the Control Station. In this case, a value of 0.0 disables
automatic sending of Digital Input data.
Note: Regardless of the CIT setting, Digital Inputs are always sent to the Control Station when the
SmartStix I/O Module powers -up, and when specifically requested by the Control Station.
