Binary Inputs
The SEL-751A dynamically creates the default Binary Input map after you
issue an R_S command. The SEL-751A uses the Part Number to determine
the presence of Digital Input cards in slots 3, 4, and 5. If present, each digital
input point label, INx0y (where x is the slot number and y is the point), is
added to the default map in numerical order.
Analog Inputs
The SEL-751A dynamically creates the default Analog Input map after you
issue an R_S command. The SEL-751A first checks for a voltage option in the
part number, and if voltages are present, adds VAB_MAG, VBC_MAG,
VCA_MAG, VAVE, 3V2, P, Q, S, and PF to the default DNP map. The
SEL-751A then uses the Part Number to determine the presence of Analog
Input cards in slots 3, 4, and 5. If present, the SEL-751A adds each analog
input point label, AIx0y (where x is the slot and y is the point number), to the
default map in numerical order to the DNP map.
Binary Outputs
The default binary output data map is populated with the RB01–RB32 point
labels.
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-751A assigns some special operations to the code portion of the
control device output block command. The example in Table D.1 4
demonstrates how you may use this functionality for both paired and non-
paired points. Because the SEL-751A 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.
NOTE: Dead-band changes via
Object 34 are stored in nonvolatile
memory. Make sure to reissue the
Object 34 dead bands after a warm
(HIS C) or cold start (power cycle).
