Bit-Strobe
The “Bit-Strobe I/O Connection” is always a 1 to n multicast connection. In other
words, a master can reach all slaves that support the Bit-Strobe command.
Transmission is simultaneous. This allows for slave synchronization.
The length of this master message is limited to 8 bytes. Each node address in the
network is assigned a bit within the 8 data bytes. The reaction of the slave, whose
bit is set, is specific to the application. The slave responses must be defined and
known to the PLC. Each slave can return 8 bytes of data as a response. The order
of responses depends on the response time of the individual slaves and the
respective node address. If all slaves response to the Bit-Strobe command at the
same time, the order of sending on the CAN bus would be determined by the node
address (bit arbitration).
