OCI Parameters
Chapter 38
38-8
Function
Before changing this parameter make sure you have read and understand
the watchlist concepts outlined on page 38-5.
There are four “OCI Backgrnd Buffer__Size” parameters. One for each
connecting OCI station. Use this parameter to specify the size (in bytes) of
the background watchlists for each connecting OCI station. Each OCI
station that connects to the 9/Series creates its own background and
foreground watchlists. Most data items are loaded onto the controls
background watchlist. Refer to your 9/Series OCI API developers guide
for a listing of the data items that are background and their data types.
Axis
Parameter
Number Parameter Name
All [336] OCI Backgrnd Data Buffer1 Size
All [337] OCI Backgrnd Data Buffer2 Size
All [338] OCI Backgrnd Data Buffer3 Size
All [339] OCI Backgrnd Data Buffer4 Size
Range
50 to 10000 bytes
Notes
Important: You can assign an OCI station to a specific watchlist buffer
when the OCI stations data server is configured. The parameter
“OCIDataBuffer” in the OCIDSCFG.INI file selects the watchlist for that
OCI on any given CNC. See your 9/Series OCI installation manual for
details. If one OCI station has an application program that requires more
watchlist space than other connecting OCI stations, you can specify a
larger background watchlist number here. Than make sure the larger OCI
station always connects to this larger watchlist by assigning the
“OCIDataBuffer” parameter in the OCIDSCFG.INI file to this larger
watchlist buffer number.
This is a global parameter; the value set here applies to all axes.
