@mdturnerphys Sure! We expect to release the new Mervis IDE and required tutorials on our new knowledge base this Friday.

Hi @Kai,

The license code is used for enabling the cloud database and cloud VPN, which gives you a secure way of accessing data on your device remotely.

Hope this helps

Hi Thomas,

it's working now together with a Mervis OS 1.7 beta.
Thanks a lot!
Best Regards,
Kai

Dobrý den @kaniiisek, jsem rád, že Vám spojení funguje. Proč nefungovalo dříve je těžké odhadnout, musel bych mít k dispozici Váš projekt.

S pozdravem,
Martin Kudláček

@derinex Thanks for the topic. Will update the Mervis documentation for all models

<port id="2">RS485-1</port> <port id="3">RS232-2</port> <port id="10">USB1</port> <port id="11">USB2</port>

@martin-kudláček Hi, I'm also trying to use 1.7beta, can you send me new MervisIDE 2.1.3 link, please?

It's working with image 1.7b and development version. Thanks

Hello again @JasperJackson,
as we discussed via email, the image 1.7 and latest development version of MervisIDE fixes the problem you have encountered. Another problem occured when reading states of the digital inputs. We discovered a problem in the installation package and issued a new version. To fix your problem, SSH into the PLC and issue these commands:

sudo su dpkg -P evok-mini pigpio apt-get update apt-get clean apt-get install evok-mini reboot

For clean image 1.7 you just need to install the fixed evok-mini package.

Hello @steve-vandenbussche,
the serial ID for dynamic ports starts with 100.

The return value of io.openport() is indeed type io.commhandle and you should be able to get the information whether the port has been opened or not. I will investigate the actual functionality as this looks like it's broken.

Martin

Dobrý den Dalibore,
toto je velmi jednoduché. V MervisIDE přidáte na PLC "Serverový kanál" a nastavíte protokol na ModbusTCP. Přidáte serverové zařízení, nastavíte mu IP adresu, port a modbusovou adresu, na které bude přístupné. V detailu zařízení pak namapujete registry a coily na příslušné proměnné. K proměnným pak přistupujete přes síť z libovolného Modbus Master zařízení / programu.

Místo ModbusTCP je možné použít i ModbusRTU, kde nakonfigurujete příslušný RS485 port a nastavíte modbusovou adresu.

Nemám ověřenou funkcionalitu na starém IDE (2.0.x), ale v novém, které bude začátkem září je toto plně funkční.

Martin

@Andmo
That looks about right - could you describe in more detail the problems you are having?

It's quite hard to tell from the screenshot.

Hello @arolli,
the new Mervis release is being expected in upcoming weeks, hopefully by the end of this month.

@joe160781 Discussed in email communication

ok i just figured out i apparently changed the resolution somehow with some random clicking to get the sensor going. (i found the PDF file on how to change resolution of the DS18B20)

Then I would suggest you to study the API. It really allows you to have "gateway" that acts as a real MervisDB. In MervisIDE you would point the "Mervis DB parameters" to http://your.server.com/save and your software on this server can store the data internally to MySQL, InfluxDB or wherever you like.

Adding a custom JS scripts into HMI is not supported.

It works!! Thanks!!

@tomasknot
Aha, thanks, that is very helpful. In that case,
Could you please share a picture of the required bypass on the Unipi board?

Hello @emanuele84 ,
the Mervis DB is hosted in cloud, but you can write wrapper for the API call and implement any local storage you want. You can learn more about this here: https://kb.mervis.info/doku.php/en:mervis-db:10-api?tns
