There is a chance that the Raspberry Pi power supply complies with the USB3 standard and needs to negotiate the power requirements with the device under power. If this is the case, the watchdog has not implemented the standard and the power source does not start. If you could test with a normal...

A link to the sensor you use, and a diagram or detailed explanation for the connections, will help us to debug the problem.

The fact that the WDT is not implemented in OpenPLC should not be a problem at all. If you have access to the Raspberry Pi console, please run "i2cdetect -y 1" in both situations (working and not working) and share the outputs. BAS having all the inputs stuck at 0, looks like an I2C...

Hi, We no longer produce this card, but the drivers remain on GitHub: https://github.com/SequentMicrosystems/lkit-rpi We will place the tutorials there also.

Thanks for the update.

So, the strange wdt is working from the 24V, but not working when powered through usb-C connector. If this is the case, it might be because we did not implement the power negotiation feature of the USB 3 standard. If you are asking if we plan to add the Watchdog to the OpenPLC, yes, but hard to...

Hi, Sorry, I am not able to look into this deeply. I wrote the libraries a long time ago, I don't remember much, so I need some time to reconnect to the subject. Unfortunately, I need to finish my current job before that. Here is the editor I worked with:

Hi, Thank you for sharing.

Hi, Thank you for the suggestion, we will consider it. The problem is that adding a power source will change the form factor and the price of the Smartfan.

Hi, Our last library was designed with OpenPLC editor V2.01. Give us some time to test with the newest version, but in the meantime, if it's not too hard, you can post on the OpenPLC forum to see if someone has the same problem.

I am sorry for asking, but are you plugging the power into the Watchdog or into the Raspberry? Is acting very strangely

If you could measure some voltages or retrieve them from the watchdog before raspberry shuts down, will help us debug. You can open a terminal and run: wdt -g v wdt -g vb wdt -g vr and if you can do this multiple times to see the evolution will be perfect

Even though we have changed a lot from the first 8-RTD card, we keeped the software compatibility. Your card should work just fine with the latest Node-RED driver (nodes). There might be some missing features, but the main functionality is the same. I am a little confused, you put in the same...

I am glad you solved it.

Thank you for sharing.

Thanks for reporting this, and sorry I did not figure it out.

You might need to reinstall the Node-RED completly

Hi, All Sequent card nodes are using i2c-bus module: https://github.com/fivdi/i2c-bus Please run npm install i2c-bus

Hi, Thank you for shering your experience. We tested the Modbus implementation with a PC program called qModMaster and in Python using the pymodbus library, but we will try to accommodate Node-Red as well. Alex

The example use Python but is easy replaceable with Node-RED.
