NS-Link Device Driver Configuration
TCP Timeout Multiplier
Default = 1ms
Use the TCP Timeout Multiplier option to modify two timers used in
TCP/IP socket communications.
The first identifies how long the TCP protocol should wait before
timing out an attempt to open a TCP channel. The TCP Timeout
Multiplier default is 1 and the timer defaults to 500 ms when the
TCP/IP address method is used to communicate with a device.
If the TCP Timeout Multiplier is set to 2, the timer would now be
1000 ms, or 1 sec. If the multiplier is 4, the new time-out period
would be 2000 ms, or 2 sec.
The second timer defines how long the driver will wait for a
response from the DeviceMaster when a forced release of a port is
requested. This timer defaults to 8 seconds.
If the TCP Timeout Multiplier is changed to 2, the timer would now
be 16 seconds. If the multiplier is 4, the new time-out period would
be 32 seconds.
Scan Rate (ms)]
Default = 10ms
Typically, you should leave the scan rate set to the default value (10
ms) for most applications. To adjust latency for time-critical
applications, select a longer or shorter interval from the droplist, or
type in the rate (2 to 50). If a value larger than 50 is entered, the
maximum of 50 is implemented.
Note: The faster the scan rate (lower number), the higher the load
on the system processor.
Verbose Event Log
Default = Disabled
Selecting this option causes detailed messages to be sent to the
operating system Event Log. This added information can be useful
when debugging communications and configuration problems
Save Configuration
Click Save Configuration to save the Device Settings for use on
another similar Comtrol device or to archive a copy of your
environments settings.
Load Configuration
Click to Load Configuration to load the Device Settings previously
saved using the Save Configuration feature.
Note: Configuration files must be for the same model with the same
port density. For example, you cannot load a DeviceMaster
PRO configuration file onto a DeviceMaster RTS or a
configuration file for a 32-port DeviceMaster RTS onto a 4-
port DeviceMaster RTS.
