Parameters
It is optionally possible to give the number of valid parameter data bytes in the first CAN data byte
Number of param- 1
eter bytes
First CAN data byte 0x2F
This is, however, not generally necessary, since only the less significant data bytes up to the length of the
object directory entry that is to be written are evaluated. A download of data up to 4 bytes in length can
therefore always be achieved in Beckhoff bus nodes with 22h in the first CAN data byte.
