There are a few hard limits, which are not documented in the NI-XNET manual
. They are, however, addressed in the NI-XNET API as error codes. These limits are:
- Maximum of 500 frames that can be used per physical CAN port/interface.
- Maximum of 8 Frame Input Stream sessions that can be created and active at any one time per CAN port/interface.
- Single sessions are limited only by system memory.
- Maximum number of sessions per system is 8192 where each session can use more than one frame, so long as the previous conditions are met.
