4–14 OCI Data Server Data Items

The 9/Series provides a dual process option which allows the use of

the 9/Series to control multiple processes. Many API data items and

commands present different data based on the process you are

looking at. Refer to appendix A and B to identify if your API data

item or command is available in two different process.

Important: Dual process options are not available for Release 1 of

the 9/PC CNC.

To specify which process your API data request or command is

targeting you can append the process number to the data item or

command following a period. For example:

NUM_AXES.1

NUM_AXES.2

would request the number of axes in process 1 and process two

respectively.

The default for all per process commands and API items is always

process 1 so the API item:

NUM_AXES

on a dual process system returns only process 1 data.

If an item or command has an argument, follow the process number

with the argument. For example:

AXIS_NAME.2,2–3

would return the second and third axis names in process 2.
