H16…H1 Determines default state of the SmartStix I/O Module’s 1st 16 Digital Outputs, if any, when
the configured Life Expectancy Time expires. If an H bit is 1, its corresponding Digital
Output, by default, holds its last state. If an H bit is 0, its corresponding Digital Output is
forced Off or On, depending on the corresponding F bit in Word 7 (Table 6.10).

H32…H17 Determines default state of the SmartStix I/O Module’s 2nd 16 Digital Outputs, if any, when
the configured Life Expectancy Time expires. If an H bit is 1, its corresponding Digital
Output, by default, holds its last state. If an H bit is 0, its corresponding Digital Output is
forced Off or On, depending on the corresponding F bit in Word 8 (Table 6.11).

6.8 Consumed Directed Data Power-Up Initialization
At power-up, the SmartStix I/O Module’s eight Consumed Directed Data words are all cleared to 0. Until
Directed Data is actually received from a Control Station, the SmartStix I/O Module will exhibit the
following behavior:
1. All Digital Outputs are Off, until Q data is received from a Control Station.
2. The device expects to receive Q data at least every two seconds.
3. The device transmits a Heartbeat every second.
4. The device transmits its Digital Input data, only when the Digital Inputs change state.
5. If Q data is received, and then not received for 2 seconds, the outputs go Off again.
6. At power-up, a request for Directed Data is transmitted to the CsCAN Network.
