Compact RIO controller Power Supply Status

[nnarra]

In one of our applications, we connected sensors to cRIO Hardware and we are monitoring data from remote PC through TCP/IP Protocol.Our problem is, we want to know the power supply status(Not manually by looking into cRIO ControllerPower LED) of compact RIO Controller from Lab VIEW front panel.

can anybody give ideas in this or any VI is there for getting this information??

Hey Naresh,

If you have a 902x controller there are some VIs that report which supply is active and what the voltage is.  Have a look at the 9022 Voltage Monitor example for more information on how to do this.

I don't see similar functionality for other controllers.  Another option would be to use an analog input module to monitor the supplies.

Hi Sebastian,

Thank you very much for your prompt reply.

We are using cRIO 9012 Controller. Is there any VI's for getting power supply information

of above mentioned  cRIO Configuration??

We are not interested to add extra module for this, Is there any alternative like MODBUS Communication??

I think if you are providing some register locations for Power Supply Information, we can easily access those

registers. Kindly give your ideas regarding this..

Hello Naresh,

The functionality you are looking for doesn't appear to be available for the 901x controllers.  There are no registers that can be read to get this information.

If the power supply you are using can communicate using MODBUS (or some other protocol), then that may be a possiblity.  If so please respond with the power supply model you are using and we can investigate further.

Otherwise, I think you will have to either upgrade your controller or add a module.

Hi Sebastian,

We got Power supply for cRIO from National Instruments only, any how please find information regarding power supply we are using.

PHOENIX CONTACT

QUINT POWER

Output                   : DC 24 V, 5A

Input                      : 100 - 240 Volts AC

Web                      : www.interface.phoenixcontact.com

I dont think so any communication option provided with this power supply...

But kindly check from your side and support me to solve this issue,

Naresh,

You are correct, there is no way to communicate with that power supply.

I don't have any other options to suggest.  As far as I know, you will have to build some sort of monitoring circuitry, either with a module or with a separate device, or you will need to upgrade your controller.

Sorry there isn't an easier answer to this, let me know if you have any other questions.
