Hi Team,

How does the watchdog work on the Monarco Hat? Is it automated or something we have to enable?

An update to the above. I'm now very sure I had a bad batch of sensors, it turns out I'm not alone. Over people have seen the same thing having bought sensors from certain websites.

Be careful when buying 1-Wire sensors as it seems there are cheaper, not so reliable ones flooding the market.

Hi Jaroslav,

Thanks for the reply, yes this was the case. With a bit of scaling added it works fine, only with slight loss of resolution. Not enough to cause issues tough.

Hi All,

I am using a voltage sensor, link below. When connected to the Monarco the signal voltage gets pulled down. My multimeter reads the signal voltage correctly at 2.64V. But when connected back to the hat it pulls to 1V.

Is this due to the input impedance of the AI? It seems to work ok if I rescale it though.

@jaroslav_sobota no problem

I found it in the AI specification in the back of the Monarco manual, 4.1.1 page 20.

Hi All,

I have a HMI that uses the “simple logger” feature. I like this feature and it works well. What I’m trying to work out is a more efficient way of selecting the string messages that it logs.

All the strings I have are alarms of some kind. But the alarms come from different places and the string selection block doesn’t really work properly for what I need. I need an alarm to be logged, but any new alarm has to shown/logged without the previous alarm needing to, or being cleared. This is where I find the string selection block fails me. Any more than 2 or 3 string options and things start to break. I’m using the binary inputs.

Do you have any hints?

Cheers

Mike

Hi All,

In the Monarco hat spec , it says the AI voltage mode range can be changed, 0-10V (range 1) or 0-5V (range 2). How is this done?

Cheers

Hi Jaroslav,

I only had 4 sensors, and I am using the Monarco hat. The sensor cables are all 1.5m long is a star formation.

I have ordered more as I think I had a bad batch. I have issues with the same sensors not working after a power loss.

I will let you know more once I have tried the new sensors.

Cheers

Hi Jaroslav,

The reason is for battery monitoring. Using an external sensor is fine. Just wondering if the hat had some way of internal measurement.

I will need it to work out battery charge etc.

Cheers

Mike
