Example 3 Multiple channel digital output sequence.
The following command sequence programs output channels 0-3 to output pre-defined sequence, as
illustrated in Figure A-1(c).
DIO,OCL
<- clear output settings
DYN
DIO,OUT0,0,HF
<- channels 0-3 prefault level=0
DIO,OUT1,1,1
<- channel 1 changes to 1 on FAULT
DIO,ODY25,%1010,%1011
<- channels 0,1 & 3 change at 25ms
DIO,ODY40,%100,%100
<- channel 2 changes to 1 at 40 ms
DIO,ODY42,0,%10
<- channel 1 changes to 0 at 42 ms
DIO,ODY106,0,%1000
<- channel 3 changes to 0 at 106ms
DIO,OUT2,0,HF
<- channels 0-3 postfault level=0
STR
<- initiate fault using STR command (or use external trigger)
Example 4 Simulated Breaker Closed (52A) Signal.
The following command sequence sets channel 0 to be “off” in postfault state and “on” in all other states.
To simulate a 52A signal:
DIO,OCL
<- clear output settings
DIO,OUT0,1,1
<- set channel 0 to be on in prefault
DIO,OUT2,0,1
<- set channel 0 to be off in postfault
Note that no command is required to set the fault state value since no change is required when the fault state
changes from prefault to fault.
Example 5 Simulated Breaker Open (52B) Signal.
The following command sequence sets channel 0 to be “on” in postfault state, and “off” in all other states.
To simulate a 52B signal:
DIO,OCL
<- clear output settings
DIO,OUT0,0,1
<- set channel 0 to be on in prefault
DIO,OUT2,1,1
<- set channel 0 to be off in postfault
Note that no command is required to set the fault state value since no change is required when the fault state
changes from prefault to fault.

Description
DIO,PCO#
Phase comparison output enable/disable
•
Valid values are 0-1
•
0 = disabled (AUXOUT15 becomes normal digital output)
•
1 = enabled (AUXOUT15 becomes programmable square waveoutput)
•
The default value is 0 (disabled)
