Input SID
*1
*1. The Input SID is incremented each I/O refresh from 01 hex to FF hex. It returns to 01 hex after FF hex. If the Input SID is
not changed from the previous transmission, it means there is no change to the input data or that there is no input data.
The Input SID immediately after the Restart Port control command
is executed is 00 hex. The Input SID after the first
divided data reception is then 01 hex, and the Input SID after the second divided data reception is 02 hex.
00 hex --- --- USINT RO Yes ---
03 Ch1 Output SID
Response
*2
*2. This is the operating status of the CIF Unit.
00 hex: Not ready to receive.
Not 00 hex: Ready to receive. The value is the Output SID of the divided data that the CIF Unit received last.
