Produced Global Data Power-Up Initialization
At power-up, a SmartStix I/O Module’s four Produced Global Data words are initialized as follows:
1. Zeros are loaded into Words 1 and 2.
2. Power-up-self-test result is loaded into Word 3; if tests passed, only PUP bit is On.
3. Module’s Device Class Number and Version Number are loaded into Word 4.
4. All four Produced Global Data words are transmitted to the CsCAN Network.
