7. [RDRL]
This command is used to read the status of one
or all of the internal relays. A ‘1’ indicates the
relay is on (closed). A ‘0’ indicates the relay is
off (open).
Command Format: [RDRLnCi]
n= Relay No. (1, 2, 3, 4 or * for all)
Ci = Unit ID (i = # from 1 to 99)
Example 1:
The PE1005 has relay number one on (closed)
and two through four are off. Send the command
[RDRL*] to check the status of all relays. The
feedback will be as follows:
1000
Example 2:
Check the status of relay number one only by
sending the command [RDRL1]. The feedback
will be as follows:
1
8. [WRRLx1x2x3x4]
This command is used to the turn the internal
relays on or off. A ‘1’ will close the relay, a ‘0’
will open a relay and an ‘X’ will leave the status
of the relay unchanged.
Command Format: [WRRLx1x2x3x4Ci]
x1=Relay #1
x2=Relay #2
x3=Relay #3
x4=Relay #4
x = 0 for open, or off
x = 1 for closed or on
x = X for no change
Ci = Unit ID (i = # from 1to 99)
Example:
Set relay 1 on, relay 4 off, and leave relays
2and 3 unchanged. In order to do this, send the
command [WRRL1XX0].
9. [WRRLk=x]
This command is used to set one or all internal
relays on or off. A ‘1’ will close the relay and a
‘0’ will open a relay.
Command Format: [WRRLk=xCi]
k= Relay No. (1, 2, 3, 4 or * for all)
x= Relay Setting (0 = open, 1 = closed)
Ci = Unit ID (i = # from 1to 99)
Example:
Set only relay 1 on by sending the command
[WRRL1=1].
10. [WRIN]
This command is used to assign a subroutine
number to be executed when one of the input
ports makes a high-to-low transition. In order to
create a high-to-low transition, connect the input
port to ground using a switch or other contact
closure device.
Command Format: [WRINn=SUBkCi]
n= Input No. (1, 2, 3 or 4)
k= Subroutine (k = # from 1 to 99)
Ci = Unit ID (i = # from 1 to 99)
Example:
Assign subroutine 10 to be performed when port
one makes a high-to-low transition. In order to
do this, send the command [WRIN1=SUB10].
Now when input port one is shorted to ground,
subroutine 10 will be executed.
11. [RDIN]
This command is used to read the subroutine
settings for the input ports.
Command Format: [RDINnCi]
n= Input No. (1, 2, 3, 4 or * for all)
Ci = Unit ID (i = # from 1 to 99)
