IR/Serial Port (Port 3) Commands
The IR port is located at Port 3 in NetLinx D:P:S nomenclature. The following IR and IR/Serial
Send_Commands generate control signals for external equipment.
In these examples: <DEV> = device. The IR port shall support the following commands.
IR/Serial Send_Commands
Command
CAROFF
Disable the IR carrier signal
until a 'CARON' command is
received.
CARON
Enable the IR carrier signals
(default).
CH
Send IR pulses for the
selected channel.
78
Power Fail. (Used with the 'PON' and 'POF' commands).
Power status. (Shadows I/O Link channel status).
Description
Syntax:
SEND_COMMAND <DEV>,"'CAROFF'"
Example:
SEND_COMMAND IR_1,"'CAROFF'"
Stops transmitting IR carrier signals to the IR_1 port.
Syntax:
SEND_COMMAND <DEV>,"'CARON'"
Example:
SEND_COMMAND IR_1,"'CARON'"
Starts transmitting IR carrier signals to the IR_1 port.
All channels below 100 are transmitted as two digits. If the IR code for ENTER
(function #21) is loaded, an Enter will follow the number. If the channel is
greater than or equal to (>=) 100, then IR function 127 or 20 (whichever exists)
is generated for the one hundred digit. Uses 'CTON' and 'CTOF' times for pulse
times.
Syntax:
SEND_COMMAND <DEV>,"'CH',<channel number>"
Variable:
channel number = 0 - 199.
Example:
SEND_COMMAND IR_1,"'CH',18"
This device performs the following:
• Transmits IR signals for 1 (IR code 11). The transmit time is set with the
CTON command.
• Waits until the time set with the CTOF command elapses.
• Transmits IR signals for 8 (IR code 18).
• Waits for the time set with the CTOF command elapses.
• If the IR code for Enter (IR code 21) is programmed, the device performs
steps 5 and 6.
• Transmits IR signals for Enter (IR code 21).
• Waits for the time set with the CTOF command elapses.
