Bit-Strobe Message Format
The Bit-Strobe command sends one bit of output data to each XM slave whose
node address appears in the master’s scanlist.
The Bit-Strobe command message contains a bit string of 64 bits (8 bytes) of
output data, one output bit per node address on the network. One bit is assigned
to each node address supported on the network (0…63) as shown in
Figure 45 .
Figure 45 - Bit-Strobe Command
The XM-124 module uses the bit received in a Bit-Strobe connection as a trigger
event. When the bit number corresponding to the module’s node address is set,
the module collects the triggered trend data and store the spectrum or waveform
data.
Note that the XM-124 module does not send data in the Bit-Strobe response.
