Parameter Setting Request (Local Node) - Toshiba V Series Manual

4.3.3

Parameter setting request (local node)

(1) Function
This request is used to set the local node parameters of the DN311. This request can
be issued only when the DN311 is in standby mode.
After setting the local node parameters and slave device parameters, set the DN311
in run mode (transmission enabled) by following 4.3.5 Operation mode control
request. If the slave device parameters have already been set in the non-volatile
memory of the DN311, set only the local node parameters, then set the DN311 in run
mode by an operation mode control request. (Local node parameters cannot be set
in the non-volatile memory.)
