This request is used to specify an operation mode for the DN module. It is valid if the
DN311 is in neither down mode nor initialize mode. Run mode (transmission
enabled) is available only when the DN311 is in standby mode and has its local node
parameters set. When the DN311 is set in run mode, slave device data is allocated to
the input/output data areas.
