Hi Mike, I wasn't 100% right, sorry for that. It is prohibited to use both flags for AI at the same time by the compiler. The solution is not that straightforward however it is possible: use just "MNR_AI1" flag to set the current mode use SDC write flag, address 0x00A - bits 01 and 02 (see docs: https://github.com/monarco/monarco-hat-documentation/blob/master/Monarco_HAT_SPI_Protocol.md#service-channel-register-description) when in current mode you need to manually convert the value by following formula 10V = 52.475 mA If you need any additional help, let me know. Cheers, Tomas

@RexPeter thank you for that, that is actually very useful. Cheers Mike

Hi Mike, glad I could help. A "good execution rate" always depends on the project. 20 milliseconds might be too long (controlling RPM of a motor or detecting pushbutton presses or counting pulses from a flowmeter) or way too short (temperature control). It's the responsibility of the system engineer/designer to find the appropriate timing. As for Modbus, we typically use twice the rate of the task which is using the data provided by the Modbus driver. Best regards Jaroslav

Thank you Jaroslav, you learn something every day! That will help more than you know with all of my projects. especially ones with process models Cheers Mike

Volunteering brings forth the opportunity to connect with others doing similar work. For a businessperson, these connections can be an invaluable resource For More Information.

Hi Jaroslav, No, not causing an issue as such. Setting the LIN block in such a way fixes the problem and allows the fan to operate correctly. Cheers Mike

Ok, thanks Jaroslav. I'll use a combination of the ALB and what I currently have to achieve both. This way I'll get both live HMI and logged alarms. Cheers Mike

Hi Jaroslav, Thank you for the help. I will give that a go and let you know what happens. Cheers Mike

Hi Mike, unfortunately the REXYGEN runtime won't run on an ESP32, however you can integrate it with other REXYGEN enabled device using REST API and exchange data. Have a look at example "0302-11 ESP8266 REST API", which is originally meant for ESP8266 - I believe that the code will work also for ESP32 (with minor tweaks - don't have any ESP32 on my desk available for testing). Let us know about your progress. Regards, Tomas

Hi Jaroslav, That’s awesome, I will try this out during the week. I’ll let you now how it goes. Cheers Mike

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. Cheers Mike

Hi Mike, not sure if I understand correctly what is the issue. Can you provide more information? Can you share screenshot of the project part and a sketch of desired behaviour? Is the issue about setting binary inputs sequentially which produces more logs to be written? Thanks. Cheers, Tomas

@jaroslav_sobota no problem

Hi Mike, thanks for clarification. I have no experience with that, but the Maxim MAX1721x with 1-Wire interface seems to be ideal for such a project with the Monarco HAT. Jaroslav

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. Cheers Mike

Thanks Jaroslav, So using a not block would be the preferred way for making it work for cooling. Cheers Mike

Hi Jaroslav, I will email you the documentation for the device. Cheers Mike

Hi Jaroslav, Awesome, thank you for your help. Cheers Mike

Hi Tomas, Thank you for your help. I understand how it works now, what you provided is where i wasn't sure what to do. It makes sense to me now. Cheers Mike
