IR / Serial Ports Channels

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 Ports Channels

00001 - 00229 IR commands.

00229 - 00253 May be used for system call feedback.

00254 Power Fail. (Used with the 'PON' and 'POF' commands).

00255 Power status. (Shadows I/O Link channel status).

IR/Serial Send_Commands

Command Description

CAROFF

Disable the IR carrier signal

until a 'CARON' command is

received.

Syntax:

SEND_COMMAND <DEV>,"'CAROFF'"

Example:

SEND_COMMAND IR_1,"'CAROFF'"

Stops transmitting IR carrier signals to the IR_1 port.

CARON

Enable the IR carrier signals

(default).

Syntax:

SEND_COMMAND <DEV>,"'CARON'"

Example:

SEND_COMMAND IR_1,"'CARON'"

Starts transmitting IR carrier signals to the IR_1 port.

Send IR pulses for the

selected channel.

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.
