Binary Inputs
The SEL-787 dynamically creates the default Binary Input map after you
issue an R_S command. The SEL-787 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, IN
x
0
y
(where
x
is the slot number and
y
is the point), is
added to the default map in numerical order.
Analog Inputs
The SEL-787 dynamically creates the default Analog Input map after you
issue an R_S command. The SEL-787 first checks for a voltage option in the
part number, and if voltages are present, adds IN_MAG, VAB_MAG,
VBC_MAG, VCA_MAG, VAVE_MAG, 3V2_MAG, P, Q, S, and PF to the
default DNP map. The SEL-787 then uses the Part Number to determine the
presence of Analog Input cards in slots 3, 4, and 5. If present, the SEL-787
adds each analog input point label, AI
x
0
y
(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-787 assigns some special operations to the code portion of the
control device output block command. The example in
demonstrates how you may use this functionality for both paired and non-
paired points. Because the SEL-787 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).
