Command Description EXB Modules
POF Turn OFF a device connected to an IR port based on the status of the
corresponding I/O Link input.
• If at any time the IR sensor input reads that the device is ON (as in
having been manually turned on at the front panel), IR function 28 (if
available) or IR function 9 is automatically generated in an attempt to
turn the device back OFF.
• If three attempts fail, the IR port will continue executing commands in
the buffer.
• If there are no commands in the buffer, the IR port will continue
executing commands in the buffer and trying to turn the device OFF
until a 'PON' or 'POD' command is received.
• If the IR port fails to turn the device OFF, a PUSH and RELEASE is
made on channel 254 to indicate a power failure error.
• You can only use the 'PON' and 'POF' commands when an IR device
has a linked I/O channel.
• Channel 255 changes are disabled after receipt of this command.
Syntax:
POF
Example:
SEND_COMMAND IR_1,"'POF'"
Sends power down IR commands 28 (if present) or 9 to the IR_1
device.
Note: When an IR/SERIAL port is linked and in POF state, the time
delay set by the PTOF Send Command (page 44) is used for power
pulses sent out the port. See the Input Linking section on page 27 for
details.

PON Turn ON a device connected to an IR port based on the status of the
corresponding I/O Link input.
• If at any time the IR sensor input reads that the device is OFF (such
as if one turned it off manually at the front panel), IR function 27 (if
available) or IR function 9 is automatically generated in an attempt to
turn the device back ON.
• If three attempts fail, the IR port will continue executing commands in
the buffer and trying to turn the device On.
• If there are no commands in the buffer, the IR port will continue trying
to turn the device ON until a 'POF' or 'POD' command is received.
• If the IR port fails to turn the device ON, a PUSH and RELEASE is
made on channel 254 to indicate a power failure error.
• You can only use the 'PON' and 'POF' commands when an IR device
has a linked I/O channel.
• Channel 255 changes are disabled after receipt of this command.
Syntax:
PON
Example:
SEND_COMMAND IR_1,"'PON'"
Sends power up IR commands 27 or 9 to the IR_1 port.
Note: When an IR/SERIAL port is linked and in PON state, the time
delay set by the PTON Send Command (page 44) is used for power
pulses sent out the port. See the Input Linking section on page 27 for
details.
