| + | 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> |
