2.5 Combined with GCAN- 8000series
The state of the digital input is represented by two byte
For example: the GCAN-IO-8000 module node number is 1, the channel 1 of
the first GC-1502 module count 28685, and the frequency is 56849Hz, then the
CAN data frame ID sent by the GCAN-IO-8000 module is 0x181, and the data
length ( DLC) is 8. The frame data is 0x0D, 0x70, 0x00, 0x00, 0x11, 0xDE,
0x00, 0x00. The following table lists a common counter status and its
corresponding status data.
