[WebDAQ 504 Error: The DAQ Service is not running]

Hello,

thanks for the reply.

In the error message it states "See log file for details before restarting", how can I get the log file when I can not access the web gui?

Kind regards,

Tobias

[WebDAQ 504 Error: The DAQ Service is not running]

Hello,

When i want to access the webdaq web interface following Error appeared (attached image).
The ftp server can be reached but all Rest API requests are declined and after login to the webinterface only the error message apears.

The device will be placed in a remote location, Is it possible to restart the device over ssh, telnet, etc.?

Kind regards

Tobias

Hello @Fausto

I connected the relay contacts to the DIO 0 on the WebDAQ 504, but I only get a 5V (High) reading.
On the REST API Help (https://www.mccdaq.com/downloads/WebDAQ/REST-API/1.0.0/webdaq-rest-api.html#digital-information-digital-bit-get) it reads:

Quote

Bits intended to be used as input should be left at the power-up default value of 1.

But this results in a value of 1 (5V) when the relay contact is open or closed.
How can I get a 0V reading when the relay contact is open?

 

Kind Regards

Tobias

[WebDAQ 504 Inductive Proximity Sensor (PnP) as Keyphasor]

Hello,

can I connect a Inductive Proximity Sensor with PnP output configuration with e ouptut voltage of 0-24V to the AI of the WebDAQ?
On page 7 in the datasheet it reads:

So can it handle the 24V pulse signals but only reads a max 5V signal?

Kind Regards

Hello @Fausto

thank you for the fast response, yes we want to read 0-5 VDC on the input pins of the WebDAQ.

[WebDAQ 504 digital input wiring]

Hello @Fausto

so if we connect to the relay contact a 5VDC source this should work?

Kind Regards

Hello @Fausto

We are using the DIO lines only as input and connecting relay contacts to the I/O lines.
Is this configuration possible?
