Does anyone know of a technique to automatically detect the presence, connection, or disconnection of a TEDS sensor on a NI-9219 modules in a 9014 cRIO / 9111 FPGA?
We are using the Dallas DS2433 chips for TEDS. In another windows application, we used the DS9097-S09 reader on a COM port, and scan it periodically for the DS2433 presence pulse. If the pulse remains, continues on with application as normal. If the pulse goes away, or starts new on another channel, re-acquire TEDS information. Continue scanning for pulse changes...
With the NI-9219 module, I have not found any other VIs or property nodes which would allow me any mechanism of detecting this presence pulse or any other change in TEDS. This all stems from the fact that reading TEDS takes 30 seconds or more, and I can't continue with DAQ while the TEDS is being read, so I can't just periodically scan the inputs.
Any ideas are welcome.
