sm
(stands for: send measurement value, R2/3 instruction)
The addressed device is to transmit the measurement value read in last to the controller.
This value is accompanied by a flag which indicates whether or not the value was already
read in on a previous occasion.
1 -> The measurement value is new and has not been read in previously.
0 -> The measurement value has been read in previously.
The transmission format can be specified with the set-format instruction. However, this
instruction is considerably slower than the pv instruction.
Example:
Master transmits:"Slave at address 48. Set your
response delay to 50ms!"
