Mervis CloudAccess

  • A technology that replaces the use of VPN for remote data communication while minimizing latency.
  • The connection is initiated from the PLC to the cloud - communication, therefore, does not require a public IP or port forwarding.
    • An encrypted connection is established to cloudaccess.mervis.info:23010/tcp
  • A separate direct encrypted TCP connection is established for each client - internal communication can therefore use an unsecured protocol (e.g., Modbus TCP) without compromising security.

Mervis IDE

  • CloudAccess communication settings are not available on all platforms.

  • In the profile for MervisCloud, set the certificate slot. It should point to the slot where the `isrgrootx1.pem` certificate is uploaded. If the customer doesn't know which certificate slot contains the certificate, or if it hasn't been uploaded yet, it can be checked in the Transfer/Certificate Manager tab. Link to the certificate: https://letsencrypt.org/certs/isrgrootx1.pem

Teltonika

  • You need to have the CloudAccess package installed (contact technical support to obtain the correct packages for your firmware version).

scp .\vuci-app-cloudaccess-api_1_mipsel_24kc.ipk root@192.168.1.1:/tmp/
scp .\vuci-app-cloudaccess-ui_1_mipsel_24kc.ipk root@192.168.1.1:/tmp/
  1. SSH into the router and install the packages:
ssh root@192.168.1.1
opkg update
opkg install libstdcpp
opkg install /tmp/RUT9M_cloudaccess_1.0.0-1_mipsel_24kc.ipk
opkg install /tmp/vuci-app-cloudaccess-api_1_mipsel_24kc.ipk
opkg install /tmp/vuci-app-cloudaccess-ui_1_mipsel_24kc.ipk
/etc/init.d/uhttpd restart
/etc/init.d/rpcd restart
  1. Setting up Modbus TCP over Serial Gateway:
    1. Navigate to Services > Modbus > Modbus TCP over Serial Gateway.
    2. Add a new instance (e.g., “Demo”) and select rs485 as the Device name.
    3. Configure the serial parameters: Baud rate 9600, Data bits 8, Stop bits 1, Parity None, Flow control None.
    4. Set Listening IP to 127.0.0.1 (to use the connection through Mervis CloudAccess) and Port to 502.
    5. Select User defined for the Server ID configuration type, and enter 1 as the Server ID.
    6. Click Save & Apply.
  2. Configure CloudAccess Client: Go to Services > Mervis CloudAccess to configure your server host, port, and TCP server channels.

Teltonika RUT906 RS485 Wiring

For a 2-Wire Network setup connecting a serial device to the Teltonika RUT906, follow this wiring scheme:

  • Wire the device's RxTx- to D_N on the RUT906.
  • Wire the device's RxTx+ to D_P on the RUT906.
  • Wire the device's GND to GND on the RUT906.
  • On the RUT906 terminal block itself, bridge D_N with R_N, and bridge D_P with R_P.
