4 FMS IO elements created:<br> | |||
* Tell Tale ID0<br> | |||
* Tell Tale ID1<br> | |||
* Tell Tale ID2<br> | |||
* Tell Tale ID3<br> | |||
Each ID represents Block ID of Tell Tale. | |||
Tell Tale | <bR> | ||
IO elements store information that is received from FMS Tell Tale Status message (CAN ID - 0x00FD7D).<br> | |||
Status message sends Data Block information in Data Byte 1. Block ID is determined by Data Byte 1 first 4 Bits. Example in hexadecimal first 4 bits where X – random byte value.<br> | |||
# X0<sub>16</sub> – Block ID 0 - FMS IO element Tell Tale ID0<br> | |||
# X1<sub>16</sub> – Block ID 1 - FMS IO element Tell Tale ID1<br> | |||
# X2<sub>16</sub> – Block ID 2 - FMS IO element Tell Tale ID2<br> | |||
# X3<sub>16</sub> – Block ID 3 - FMS IO element Tell Tale ID3<br> | |||
<br> | |||
Once Block ID is captured all 8 bytes of Tell Tale message are saved to corresponding Tell Tale IO element.<br> | |||

After 4 seconds (1000 ms per Block ID) all values will be captured again. Device checks last saved value of Tell Tale IO elements and if it is changed – values are updated. | After 4 seconds (1000 ms per Block ID) all values will be captured again.
