Hi All,
I have a remote application I am about to put into he field. Is there a way of connecting a windows machine directly to the Monarco Hat yet (ethernet cable)?
I'm unable to connect it to a local network, or machine yet. But I still need to down load data easily when I visit site.
Cheers

@reitinge Hi Jan,
That works extremely well, even better once made into a small subsystem! Thank you for your help as always.

Hi All,
I have an energy meter I am using, connected via Modbus. The issue I have is the kwh figure in the meter can not be reset to zero, currently it is up to 9124.0 kwh. When I start a new test I'd like to reset the logged kwh figure.
What is the best way of doing this via the REX program? I wondered about saving the last know value from the Modbus register and then subtracting that to give me a virtual reset and start from zero again.
Thoughts?
Cheers
Mike
@cechurat Thank you Tomas,
It works perfectly now. I really like this method, good to learn new things.

@cechurat Thank you Tomas,
I almost have it working correctly. What have I done in the RTOV blocks for the TRNDV to not show the last 3 values correctly? They are only shown as zero (sig Amb is zero anyway). I have tried changing the offset with no luck.
Cheers

@cechurat Hi Tomas,
Is this how you achieve it? Then point the HMI Component at the TRNDV block? Signals are extracted in the same order as they enter the RTOV block?
Cheers

Update,
I have now tried a 3rd Monarco and it works as perfectly as the second. How can I test the 1st Monarco to see if it has a fault?

Update.
I have done some testing on the two new Monarco I have. I'm not sure what is correct but my findings are.
On an older Monarco I have, there is continuity between the pi and the aluminum case of the Monarco. I do not see any voltage leak on this. I think this is because the HDMI port is pressing against the case, providing a ground link.
On the two new Monarco there is no continuity between the pi and aluminum case. None of the Pi touches the case so it is isolated.
This might be normal, it is just something I have never observed before!
Should the Pi be grounded to the aluminum case?
Cheers
Mike
Hi Tomas
I solved this by swapping the Monarco for one that I know works. Could that Monarco have an issue, it's new? It's the same one mentioned with the strange voltage leak I posted about, https://forum.rexygen.com/topic/209/leakage-from-usb
