Self-Station No - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Self-station No.

Specify this when more than one external device (m stations) and more than one C24s (n stations) are connected with the
multidrop connection.
Specify the fixed value (00H) for any cases other than multidrop connection in a m:n basis.
When external devices are connected with the m:n multidrop connection
Specify the station No. of request source external device, 0 to 31 (00H to 1FH).
For the station No. (m stations) of external devices, the value which is not set to C24 (n stations) of the multidrop connection
is used.
(The total of 'm' and 'n' is up to 32 stations.)
