Function
This parameter specifies the DNP function for the command list object. The
object type determines the value of the functions permitted. For example, the
only function permitted for binary input data points is the read function (Function
Code 1). For counter and output objects, more functions are available.
Address In Slave
This value must be greater-than or equal to zero. If it is set to a value less-than
zero, the command will be ignored. This parameter specifies the starting point
address to consider in the IED unit.
Point Count
This parameter defines the number of points in the IED unit. Refer to the
discussion above for the interpretation of this parameter's values for the different
object types.
DNP DB Address
This parameter defines the starting location in the DNP database to be used with
the command. If the parameter has a value of –1, the DNP database is not used
with the point.
IED DB Address
This parameter defines the starting location in the IED database to be used with
the command. If the parameter has a value of –1, the IED database is not used
with the point.
The IED database is the only database that will send and receive data to and
from the PLC processor.
Poll Interval
This parameter specifies the minimum frequency at which the module should
execute the command. The value is entered in units of seconds. For example, to
execute a command every 10 seconds, enter a value of 10 in the field. A value of
0 for the parameter implies that the command should be executed every scan of
the list.
