      Hello,

      I have a problem with evok and L513. Can't access any relay from 2_01 to 2_05 from evok web interface or api.
      What I'm doing wrong? Do I need to enable anything in evok config?

      thanks

        Hello @valtert, can you please post the /etc/evok.conf?

          Hi @Martin-Kudláček, we used the stock image from here https://kb.unipi.technology/_media/files:software:os-images:unipian-neuron-os-2019-01-07-v1.9.zip
          Today tried to install evok on a stock Raspbian image and now have access to all relays. But a different problem arose. By L513 spec all the analog outputs 3_0* should be dual mode - current or voltage. In the evok web interface don't have the option to choose between voltage/current for those AO's, it's only voltage.
          Am I doing something wrong, there's a different way to set AO to be current?

            Hello @valtert,
            the AOs on group 2 and 3 and on the extensions are only capable of voltage output. Can you please show me, where is the specification you mentioned? It needs to be corrected.

            Thank you,
            Martin

              “9 analog outputs (AO) feature two modes - 0-10V DC voltage or 0-20mA direct current. AI serves for control of devices with analog input, such as three-way valves, lighting dimmers etc. Group 2 analog outputs of the M503 (AO2.1-2,4) feature 0-10V voltage only.”

              From the above we understood that all the AO have the option to switch to current...

                Hello @valtert,
                the description on the page is misleading. The real situation is this:

                Analog output on Group 1 is capable of outputing 0-10V, 0-20mA and measuring resistance up to 100kOhm
                Analog outputs on Group 2 and 3 and on the extensions are only capable of outputing 0-10V

                Same goes for Neuron and Axon product line. If you need second AO in current mode for your project, you have two options:

                • add a second PLC as a "dumb" extension and communicate with the master PLC via ModbusRTU, ModbusTCP or SSCP
                • purchase a 3rd party ModbusRTU IO module, such as this: https://www.advantech.com/products/gf-5vtd/adam-4024/mod_5e18f39b-38ef-4033-98f9-1ede917139ee

                I am sorry for the incovenience, we will fix the product description shortly.

                Best regards,
                Martin
