Basic SLIO backplane bus In<strong>for</strong>mation:<br />
Single master system<br />
Up to 64 slave (Node) stations<br />
Asynchronous, serial data transmission with 48 MBit/s over Point to Point LVDS physic<br />
Additional alarm line <strong>for</strong> initialization and asynchronous event communications from node to master<br />
Full system detection from SLIO master without external in<strong>for</strong>mation on module configuration<br />
Error detection mechanism:<br />
CRC code with Hamming distance 4 <strong>for</strong> every telegram (all 3 bit errors will be detected)<br />
Watchdog function inside every node <strong>for</strong> SLIO master observation<br />
“Auto shut down” in case of SLIO master malfunction<br />
Retry statistic <strong>for</strong> early detection of possible transmission issues<br />
Time-synchronisation:<br />
Every node has its own clock with 1µs resolution<br />
All node clocks are synchronized with the SLIO master (accuracy
