DETAILED DESCRIPTION:
The SADDR{value} command is used to set the unit address of a SmartMotor™, where "value"
is an integer between 0 and 120. Separate addresses allow multiple SmartMotors to share a
common communication channel and still differentiate themselves.
The SADDR command is typically one of the first commands in a downloaded program. In an
RS-485 network, where all communications go over the same two parallel wires, the SADDR
command must be in the program. Whereas, in an RS-232 network, where communications
travel from one motor to the next, addressing can be accomplished from a host or master
motor.
The address can be from 0 to 120. Address 0 is the global address (the motor has no unique
address); it is used to talk to all motors on a network at once.
EXAMPLE:
SADDR1 'Set address to 1
When given a nonzero address, a SmartMotor begins to listen to commands after it receives
its own unique address or the global address byte from the network. There is no need to
repeat the address byte with subsequent commands intended for the same motor. The
particular SmartMotor will continue to listen to commands until it receives a different address
byte, after which commands are ignored. The echo function of the SmartMotor is not affected
by the addressed state. That is, if told to echo, then a SmartMotor will echo regardless of
whether it is listening to commands or not.
