Description
This register stores the length of the received message data.
If the message that will be received exceeds 8 bytes, a multi-
packet message split into 8-byte packets will be received. After
the multi-packet message has finished being received, the split
data is combined and stored in the data storage destination.
If the length of the received message data is longer than the
maximum data length, the maximum data length is stored and
100 is stored in the receive results status.
This register stores the receive results. To initialize this register,
write "0".
For details on the receive results status, see "Receive results
status" on page 8-16.
Stores the action flag for receiving.
When the internal receive buffer was overwritten by the next
message before the message data stored in the receive buffer
could be written to the data storage destination, this register
turns on for one scan.
