DNP3 in the SEL-2414
Binary Inputs
The SEL-2414 dynamically creates the default Binary Input map after you issue
an R_S command. The SEL-2414 uses the Part Number to determine the pres-
ence of Digital Input cards in slots 3, 4, 5, and 6. If present, each digital input
point label, INx01–INx08 (where x is the slot number), is added to the default
map in numerical order.
Analog Inputs
The SEL-2414 dynamically creates the default Analog Input map after you issue
an R_S command. The SEL-2414 uses the Part Number to determine the pres-
ence of Analog Input cards in slots 3, 4, 5, and 6. If present, the SEL-2414 adds
each analog input point label, AIx0y (where x is the slot and y is the point num-
ber), to the default map in numerical order. The SEL-2414 then looks for a Cur-
rent Card, and if it finds one, adds IA_MAG, IB_MAG, IC_MAG, and IN_MAG
to the DNP map. Then, the SEL-2414 checks for a voltage card, and if one is
installed, adds VA_MAG, VB_MAG, and VC_MAG to the default DNP map.
The firmware will check to determine if an internal RTD card exists, and if one
does exist, INTRTD01–10 is added to the default DNP map. Lastly, the firmware
does not differentiate between the RTD and RTD/TC cards. If an RTD/TC card is
installed, you must change 9X to 91 manually in the part number field for slot D.
This can be performed from Access Level 2 with the PART command. After
changing the part number to 91, INTEMP01–INTEMP10 are added to the default
DNP map.
Binary and Analog Outputs
The default binary output data map is populated with the RB01–RB32 point
labels. Similarly, point labels RA001–RA008 fill the first 8 positions in the
default analog output data map.
Control Point
Operation
You can define any two RB points as a pair for Trip/Close or Code Selection
operations with Object 12 control device output block command messages. The
SEL-2414 assigns some special operations to the code portion of the control
device output block command. The example in Table D.8 demonstrates how you
may use this functionality for both paired and non-paired points. Because the
SEL-2414 allows only one control bit to be pulsed at a time, you should send
consecutive control bits in consecutive messages. Pulse operations provide a
pulse with duration of one protection-processing interval.

described in Analog Inputs. Outside that scope, they contain the
value NA.
