Set Module Address
To operate in the POLL mode, the module must have an address. If
multiple modules share the same serial line, each module must have a
different address.
For a description of the serial interface modes, see section Set Serial
Interface Mode below.
ADDR [ nn ]<cr>
where
nn = address (0 ... 99)
Example:
>addr 1
Address : 1
>
Set Serial Interface Mode
Use the SMODE command to show or set the serial interface mode. Note
that a separate SAVE command is not needed to store the new serial
interface mode setting.
SMODE [ xxx ]<cr>
where
xxx = STOP, RUN, or POLL
In STOP mode: outputting only when command is issued, any command
can be used.
In RUN mode: outputting automatically, only command S can be used.
In POLL mode: outputting only when command is issued, any command
can be used after the line has been opened using the
OPEN command.
The polling mode can be used when more than one module is connected
to one serial bus. When set to POLL state, the modules communicate one
at a time when the specific module address is called on the serial line.
See descriptions of the commands
ADDR above and OPEN on page 47.
