Set IOChannel

Set IOChannel IOExtension

Description Configures the I/O extension options that allow you to connect the Digital Input channel or input serial signal pin (when the line is configured for signal-io) to Digital Output/Relay channels or output serial signal pins (when the line is configured for signal-io) on the same IOLAN, remote IOLAN(s), and/or TCP/IP applications running on local hosts.

Syntax set iochannel <channel> ioextension enabled onoff [keepalive onoff]

set iochannel <channel> ioextension connection-method client-initiated [tcp-port <tcp_port>] [multihost onoff]

set iochannel <channel> ioextension connection-method server-initiated <host_name> [tcp-port <tcp_port>] [multihost allbackup <config_backup_host> <host_port>none]

set iochannel <channel> ioextension connection-method local-connection [<input_channel>]

Options <channel>

Specify the Digital/Relay channel or serial signal pin that you are configuring the I/O extension for. The channel can be d1, d2, d3, d4, r1, r2, depending on the model. The serial signal pins are dsr, dcd, or cts for input and dtr or rts for output.

enabled

When enabled, the digital input channel or DSR/DCD/CTS input serial signal pins can be connected to:

zA Digital output or relay (if the I/O model supports relay) channel on the same

IOLAN

zOutput Serial Signal Pins (DTR/RTS)

zA Digital output channel on another IOLAN(s) or output serial signal pins (DTR/RTS) on another IOLAN(s)

zA TCP/IP application(s) running on a host on the network

When enabled, the digital output/relay channel or DTR/RTS output serial signal pins can be associated with a digital input channel or input serial signal pins.

Default: Disabled keepalive

Enables a per-connection TCP keepalive feature. After the configured number of seconds, the connection will send a gratuitous ACK to the network peer, thus either ensuring the connection stays active OR causing a dropped connection condition to be recognized.

This parameter needs to be used in conjunction with server parameter, monitor-connection-every. The interval determines how long the IOLAN will wait during inactivity before "testing" the connection. It should be noted that if a network connection is accidentally dropped, it can take as long as the specified interval before anyone can reconnect to the serial port.
