DeviceNet Network Scanner DVPDNET-SL 6 Bit-Strobe Command 6.1 Principle of Bit-Strobe Bit-strobe is one of the standard I/O transmission methods for DeviceNet. The length of command is fixed to 8 bytes (i.e. 64 bits), and every bit corresponds to a slave. When b0 of D6282 = 0, the node 0 equipment will be selected, and it will need to respond with a message to the master. When b0 and b1 of D6282 = 0, the node 0 and node 1 equipment will be selected, and they will be to respond with a message to the master. Node 0 Node 1 Node 2 Node 14 In the bit-strobe mode, the master will not send control data to the slave node.
However, when its corresponding bit is set to 0, the slave node will have to respond with I/O data to the master. When its corresponding bit is set to 1, the slave node will not have to respond with I/O data to the master.
