Variable Name
Value
Description
Flags Enable
See discussion that follows
Node Address
Specifies the node address of the slave unit for which the
command is to be sent
Data Object
This is the DNP data object code for the command (For
issuing a CROB command refer to the following discussion).
Data Variation
This is the DNP data variation for the command
Cmd Func
This is the DNP command code to be used when forming the
command request
Device Address
This is the starting address in the device (point address) for
the command
Point Count
This field defines the number of points to request from the
slave device. If the parameter is set to a negative number
(-n), the module will only process the first -n number of
points. For example, if this field is set to -3, only the first 3
points will be accepted into the database.
IED DB Address
This field defines the internal address in the master driver's
database to be associated with the command. If the
command is a read command, the data read will be placed at
this address. If the command is a write command, the data to
be written will be sourced from this address.
Poll Interval
This field specifies the minimum number of seconds to wait
between the issuance of the command.
The value for the Flags/Enable and point count are dependent on the type of
function (input or output) being executed by the module. The two diagrams
display this relationship:
