Channels
266 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Allow Multiple
Hosts to Connect
When this option is enabled, multiple I/O channels and/or TCP/IP applications
can connect to this channel/serial signal pin.
Default: Disabled
Connect to When enabled, the channel/serial signal pin initiates communication to another
I/O channel or a TCP/IP application.
Default: Enabled
Host Name The configured host or another IOLAN that the I/O channel will connect to.
Default: None
TCP Port The TCP Port that the channel/serial signal pin will use to communicate to
another IOLAN or a TCP/IP application.
Default: 2000 for channel 1, then increments by one for each channel
Connect to Multiple
Hosts
When enabled, input channel or serial signal pin can communicate to multiple
hosts running a TCP/IP application or I/O channels.
Default: Disabled
Define Additional
Hosts Button
Click this button to define the hosts/IOLANs that this channel or serial signal
pin will connect to. This button is also used to define the Primary/Backup host
functionality.
Local connection When this option is enabled, the input or output, depending on how the channel
or serial signal pin is configured, will be associated with another local IOLAN
I/O channel or serial signal pin.
z When the channel is configured as digital input or when configuring an
input serial signal pin, the
Output Channels parameter displays all the
local digital output signals or relays that it is associated with.
z When the channel is configured as digital output, you must select a local
digital input channel or input serial signal pin on the IOLAN.
Note that the
Failsafe Action is not compatible this option.
Default: Disabled
Enable TCP
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
Monitor Connection
Status Interval
parameter found in the Serial, Advanced, Advanced Settings
tab. The interval specifies the inactivity period before "testing" the connection.
Default: Disabled
