Thanks for your reply. Now that I operate the RPis via Mervis OS would you have any idea how the read-only works there?

Thanks &

Hi,

I have the same problem. Today there was a power outage and one of my unipi1 SD cards got corrupted as well.
Sometimes it affects just one, but I already had to replace the SD cards at all 4 units at the same time. And it does not matter if it’s a power outage from the DNO or if I just trip my circuit breaker.

I use meanwell power supplies.

Any idea how this can be solved ?

Thanks

Hi,

Another time I stumble over the AI input and issues with reading 0-10V signals with the unipi1 and Mervis.
Is there any FAQ on this because I couldn’t find an FAQ or exemplary project with Mervis and the old unipi1 (but only with neuron, axion etc…) ?
The reason I ask is the conversion linear by two points. I just replaced my old brightness sensor by a new one which makes me rethink the conversion I am currently using -
X1 0
X2 115000
Y1 0
Y2 100

Where do these 115000 come from. Or better question - what is the correct conversion to transform a 0-10V signal to 0-100% with Mervis and unipi1??

Many thanks&

Hi there,

I just burned this IC. Can you tell what’s it’s purpose and the part name please ?

Thanks &

Hi Martin,

'The module (...) is compatible with both Unipi Neuron and Unipi Patron controllers, as well as PLCs from other vendors' - so it's compatible as well with Unipi 1.1 then?

Is there an extension module with only DI planned for the near future?

Cheers

Guys,

Isn't there any chance to extend the amount of DI to the unipi other than buying more unipis?
In the meantime I have 3 unipis, 1 AO board & 8 relay boards so far. Now I just need more DI to connect additional switches for manual control of the home automation.

Isn't there any elegant, of-the-shelve solution which collects the switch activity locally and communicates it to the unipi through the network (either modbus, sccp or other)?

In the past you had DI extension boards, but more often your products are discontinued, which prevents me to perform an upgrade to Neuron, Axon or other successing PLCs of yours. This makes it difficult for those who supported you from the very beginning...

Any ideas are welcome!

Thanks

Hi,

since a long time I updated the Mervis IDE version and the OS on the respective Unipi1.1's.
I had 3-5 tasks per Unipi in my solution which worked well, but now after the update the IDE pops an error with having more than 1 task per PLC.

Is that intended or a bug?!

many thanks
CKB

Ahh, just found it - BD18 Bit Composition ! :)

Hi,

quick question - Is there a function block in Mervis that can convert 4 bits (DI01-04) to an integer? I can only find converters with WORD data type as input where I would need to write the 4 digital in's to an array..

Thanks!

I found a capacitive keypad here: https://www.robotshop.com/uk/16-button-capacitive-keypad-module.html
and a module that can connect the keypad via I2C here: https://www.robotshop.com/uk/16-keys-capacitive-touch-ttp229-i2c-module.html

Before I buy it - can UniPi1 cope with this?

Thanks
