A special data type is added to the module in order to generate CROB
commands to control binary outputs. The following table shows the format to be
utilized when this command is desired:
Column Definitions Description
1 Port/Flags Set this parameter to 6 to enable the command in the list.
2 Slave Address This is the IED node address for the slave to consider on the
network.
3 Object Object type always -12
4 CROB Image (L)
Pulse Count (H)
The CROB Image parameter contains the CROB image for
the command. Refer to the following table for the definition of
this block.
The pulse count parameter specifies the number of pulses to
generate for pulse output control. This parameter has a range
of 0 to 255 as the value is a byte parameter in the CROB. If a
value of zero is entered, the operation will not execute.
5 Function Function codes 3, 5 and 6 supported. Function code 4 is
automatically sent after a successful function 3.
6 Address in Slave Point in IED to consider with the CROB.
7 Pulse Time This parameter sets the on and off time to use if the pulse
operation is to associate with this command.
8 DB Address This is address in the module's internal database to use as a
trigger for the command. If a value other than 0 is found in the
register, the command will be executed. The database register
will be set to 0 after the command is placed in the command
queue.
9 Poll Interval This field specifies the minimum number of seconds to wait
between the issuance of the command.
The value for the CROB image is that specified in the DNP specification. The
following table lists the bits that comprise this value:
Bits Definitions Description
0 to 3 Code These bits determine the control operation to be performed by
the command: 0=No operation, 1=Pulse on, 2=Pulse off,
3=Latch on and 4=Latch off. All other values are undefined in
the DNP protocol.
4 Queue 0=Normal (execute once), 1=Requeue (place at end of queue
after operation).
5 Clear This parameter clears the queue. If the value is set to zero,
the queue is not affected. If the value is set to 1, the queue will
be cleared.
6 to 7 Trip/Close These two bits select the trip or close relay. For close relay
control, set the bits to 01. For trip relay control, set the bits to
10. A value of 00 for the bits is used for single point control of
normal digital output points.
