Hi @dalibor, no, the DIs don't have this capability. Mainly because it would require to have DIVCC terminal, to ensure galvanic isolation.

@martin-kudláček Thanks it would be very nice I hope the virus disappears quickly, and that you are not affected. Here in Sweden it has only just begun in my neighborhoods. Stockholm is very affected but we live far north. I order an extra unit through your shop because of the good service.

Hello @msoenen, the Mervis mobile app is available for download in the official stores for Android and iOS. However, to use this app, you need Mervis IDE capable of deploying projects to Mervis SCADA. Currently we are working on release of such Mervis IDE, which, with any luck, will be released to public next month. Best regards, Martin

Hi @Martin-Kudláček, b86_filter is effectively the best fit for my case, many thanks!

Hi @martin-kudláček, I am not sure to undersand: It was stable during > 2 months but now, I can reproduce the issue systematically with USB port 1 (after a few hours of operation), but not when connecting the same hardware to USB port 2. Kind regards, Pascal

Hi @mmcreativ, the issue might arise, if you try accessing the IP 192.168.8.91 from another subnet. The WiFi interface doesn't have default gateway set, therefor it doesn't know how to reach different subnet. Could this be the issue? Best regards, Martin

Hello @soren, that looks like you are using Mervis IDE 2.1.3. If you can, please upgrade to the 2.2.0. Best regards, Martin

Hello @martin-kudláček, Thanks for the response. I would like to use 12 bit which will enable me the Analog input sampling rate of 240Hz as mentioned in the MCP3422 manual. Is there any way to know how to check if the current ADC resolution is 12 bits? and if it is not the resolution I need, how do I write the configuration register for ADC for 240Hz mode using I2C? Any suggestions would be helpful. Thanks in advance, Rajesh.

Hello @matt90, the speed of 1ms is very optimistic and in the real life, you will not be able to get it under 10ms with Mervis. The biggest impact on the overall performance has the Autogen functionality and as I can see from the example, you have it configured on all datapoints. Please, take a look at our tutorial about proper settings: https://kb.unipi.technology/en:sw:01-mervis:autogen-hidden Also, be aware, that the speed is not deterministic, since the program of the PLC is running in the operating system, sharing resources with other processes. Best regards, Martin

@tomas Hi, thank you very much for your great tutorial. The board lives, and works well. I start to understand how to work with addresses. Previously I made the mistake of creating one group and trying to express all the relays with data points. Now I know it was nonsense. Thanks again very much. :-)

Hello @roberts_lando, here is a complete list: https://kb.unipi.technology/en:hw:01-axon:portmap Best regards, Martin

Hello @bart-delaere, the easiest way is to use a simple DIV function block, via which you will divide the setpoint variable value by 10 before sending to AO: More systematic way, yet more prone to errors, is to use transformation on the write variable: Best regards, Martin

Hi Martin, thanks for your help and support. All running again! regards Hannes

Hello @nicola-mondinelli, I just replied to you via email, I'll repost it here: Mervis currently doesn't have such functionality. We are about to release an active 1-Wire gateway called xG18, via which you will be able to read 1-Wire sensors without the need of knowing their addresses. This will be released to public by the end of the March / beginning of the April. The OWFS subsystem is able to detect the sensors, but you still need to know which address belongs to which sensor. Best regards, Martin

Hi @sindyk, no, your PLC will work as expected. These messages are not valid and they are meant to be valid in next version of MervisIDE, where the licensing of the PLC will be mandatory. You can ignore those for now. Best regards, Martin

@martin-kudláček Thanks for the response. Will try that out.

Do you have some USB-RS485 converter to test the communication @martin-kudláček the only way to make this working is using a converter that also has GND, it's strange Unipi doesn't support this.

Hello @mmcreativ, there isn't a reboot counter per-se, but you can work with the PLC uptime. This is provided by block "PLC Time (B99)". Best regards, Martin
