Digital I/O board 9478 error code 65548 overcurrent report by channel

[PJ_Cell]

Hi All,

We are investigating overcurrent on digital outputs. This project is using the Scan Engine instead of FPGA.

Reading one of the hardware shared variables gives the error code 65548 - One or more channels are in overcurrent or overvoltage protection mode.

If we used FPGA would we be able to determine which channel is in overcurrent?

Thanks,

Paul

Hello Paul,

Yes, it can. You can use Module I/O Method and it will indicate if the module runs into overcurrent or not. The previous like is for the 9269, but it also works for the 9478. Remember that if you are using LabVIEW 2012, you won’t be able to create a method by right clicking on the I/O variable because of a known bug. A workaround for this is to open the example “NI 9269 Status Methods.lvproj” and add your target. Then you can right click on the method » Select Item » select your module.
