Communication
NOTE
•
If no response is returned, the command may not have arrived at the slave,
or the slave may not be functioning. Check to make sure all of the
communication specifications (e.g. baud rate, data length, and parity) match
between the master and the slave.
•
Station number and command name are always identical in a command and
its corresponding response (see below). This makes the correspondence
between a command and a response clear.
