Working with NI cRIO 9145

[manojrr]

Hello,

I have LabVIEW 2021 in my machine, installed required drivers and connected it with NI compact chassis 9145. I still could not detect the device in my labview environment. Can you advice me if I am missing anything?

Thanks,

Manoj

The NI-9145 is a slave device and needs a master device connected to it, like a cRIO-9074. You configure the master and slave devices through MAX under remote systems. Once configured, you can add them to a LabVIEW project.

The 2021 drivers may not work for this setup, as the EtherCAT driver only supports the NI-9145 up to version 19. It is recommended to use the same version of all the required drivers installed in the following order:
1. LabVIEW 2016 or later
2. LabVIEW 2016 Real-Time Module or later
3. NI CompactRIO Device Drivers August 2016 or later
4. NI-Industrial Communications for EtherCAT 16.1 or later
5. LabVIEW 2016 FPGA Module or later

Hello Apex Waves,

Thanks for your response. Just an added information, I am using this NI -9145 expansion chassis with the EtherCAT Ackermann Library as the master.

 "The 2021 drivers may not work for this setup, as the EtherCAT driver only supports the NI-9145 up to version 19".

When you say EtherCAT drivers only support NI-9145 upto version 19, will the following combination of things will be fine?

1. LabVIEW 2018
2. LabVIEW 2018 Real-Time Module 
3. NI CompactRIO Device Drivers August 2016 or later
4. NI-Industrial Communications for EtherCAT 16.1 or later
5. LabVIEW 2018 FPGA Module.

Let me know if any comments.

Thanks

You want all of the driver versions to match- so If you are using LabVIEW 2018, then you will want NI CompactRIO Device Drivers version 18.0 and NI-Industrial Communications for EtherCAT version 18.0.

Great. Will update my drivers accordingly. Thanks much
