Startup Command File Chapter 8
Rockwell Automation Publication HSELD-UM024A-EN-E–September 2013 43
The following is a sample startup command file that comes with the
installation:
“FTLDInt.exe”1 /uiDll=FTLDIntCtl.dll /FTDirectory=$Global /
FTContext=/ /PS=FTLD /ID=1 /host=localhost:5450 /ec=2 /pisdk=0 /
maxstoptime=120 /q /sio /perf=8 /f=1 /f=0.05 /f=0.1 /f=0.25 /
f=0.5 /f=2 /f=5 /f=10 /f=60 /f=120
For more flexibility, the FTLD interface can use an INI format file
to configure interface information. This format file does not install
with the FTLD interface, but you can create the file manually. It
should be named
FTLDInt.ini and it must be created in the same
path as the FTLDInt.exe file and the FTLDIntCtl.dll file.
The following is a sample setting file:
[FTLDIntSetting]
OnceMaxUnsolEvents=4
ScanClassToUpdateRate=1
PIOrFTLDTimestamp=0
FTLDResponseInterval=5000
Review the following for additional information.
Item Description
OnceMaxUnsolEvents The OnceMaxUnsolEvents key specifies the maximum
number of unsolicited events that the FTLD Interface can
process in each loop for each Advised Tag. The default value
for OnceMaxUnsolEvents key is 4. That is, the interface can
process 4 events for each advised tag when the interface
collects data.
ScanClassToUpdateRate For polled points, the FTLD interface calculates the update
rate from its scan time. The update rate is used while
adding an item to the FTLD server.
The algorithm is "Update Rate = Scan Time /
ScanClassToUpdateRate"
For example, if a point has a 1-second scan period and the
ScanClassToUpdateRate is 2, the FTLD Interface will use 500
ms as the update rate.
