@pianz You are probably still in Simple Mode, so you cannot create the derived profile. Check out the tutorial on our knowledge base: https://kb.unipi.technology/en:sw:01-mervis:connecting-to-unipi-via-mervis-proxy-hidden

@robl Mervis tries to maintain all possible settings when uploading new program. Select the clear flash variables checkbox and test please.

Hello @robl ,

how do you deploy the project? Are you using cold or warm restart? Do you select "clear flash variables" option?

@msoenen That is because Mervis is not able to use SSL/TSL connections to the SMTP servers. As Google describes here https://support.google.com/a/answer/176600?hl=en you have to use aspmx.l.google.com server in order to be able to send the email using an unencrypted connection but using this server you can only send the mail to Gmail/Gsuite users.

@msoenen The status should be CONNECTED in the PROXY field. If you see disabled, then the configuration is not done properly. Anyway, Mervis requires the port 6677 to be allowed for outgoing connection in order to make the proxy work.

Hello @msoenen,

I just downloaded your project and the compilation works well. Is this really the same version as you have?

@msoenen Only the device on the Modbus TCP channel, not the whole PLC.

The proxy configuration looks good. Did you upload the configuration (right click on PLC - PLC operation - PLC setup)? If you are connected to the PLC via the LAN and start the debug mode, check the Proxy information in the System Status.

@msoenen The issue is that you deleted the definition of the L203 device on the Modbus channel (if you double click on it, you will see that its empty). Delete it and insert a it again. Make sure to set the autogen on the device since you are in full mode (simple mode does that for you).

Hello @clueless

The longterm persistent data will newe be stored to the PLC since the PLC storage is not designed for such purpose. So right now, you will only see the values in the graph since the load of the page. In the future, the graph widget might be able to read the data from the online DB but that's just an idea.

The tutorial on the KB is written as a step by step guide which covers all steps that need to be done in order to make it work. What do you mean by "key value pairs"? If you are getting an error when trying to login to the DB viewer and filled incorrect credentials, then there is no data yet in the database. Check in the System status while in Debug mode that there are actually data sent to the DB. Also, make sure that the Network settings are correct so that the PLC has a connection to the Internet and can resolve DNS names.

@msoenen There is no function like this yet. The only possibilities are the Digital Setter or Digital Setter ComboBox
