Field Descriptions
The Local conn ec tion option is different depending on whether you are configuring a Digi tal Input
or a Digital Output/Relay channel. The Local connection option for Digital Input lists all the local
Digital Output channels or output seri al signal pi ns t hat it is associated with. Digital Input can be
connected to multiple local Digital Output or Relay channels or output serial signal pins. However, a
Digital Output can only be associated with one Digi tal Input channel or input serial signal pin. The
Local connection option fo r Digital Output configures the specifi c local Digital Input channel or
input serial signal pin on the same IO LAN that it is to be connected to.
For a description of the SSL/TLS parameters (not available when Local connection is configured),
see SSL/TLS Settings Tab Field Descriptions on page 113.
Configure the following parame ters:
Enable I/O
extension When enabled, the digital channel 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 outpu t serial sign al pins
(DTR/RTS) on another IOLAN(s)
zA TCP/IP application(s) running on a host on the network
Default: Disabled
Listen for
connection When enabled, the channel/serial signal pin will wait for connections to be
initiated by another I/O channel or a TCP/IP application.
Default: Enabled
Input TCP Port The TCP port that the channel/serial signal pin wil l use to listen for incoming
connections.
Default: 2000 for channel 1, then increments by one for each channel
