When handling the components, ensure that everything in the vicinity is well earthed (personnel, work- place and packaging). Do not touch electrically conductive components, e.g. data contacts. 1.7 Scope This documentation describes the device manufactured by solvimus GmbH, Ilmenau, and stated on the title page. 1.8 Abbreviations...
The MUC.one is a MUC-Controller and is intended for wall mounting. The serial number of the devices of the solvimus GmbH can be read from the housing. 2.2 Delivery variants The MUC.one is offered in two variants, and so can easily be adapted to the requirements of the particular...
An internet connection is required on the PC to launch the website, as the web framework needs to be loaded. For offline operation, solvimus GmbH can provide a tool for Windows to load the web framework from a local PC.
3.2 Discovering and accessing devices After the tool is started, it uses UDP broadcast via UDP port 8001 to discover all devices from solvimus GmbH accessible in the local network and displays them in the main window.
3.5 Access to the file system via FTP The devices from solvimus GmbH can be accessed via FTP to work directly on the file system level. This enables updates, special configurations and extended functionality (see Chapter 8). The integrated FTP server of the devices supports both FTP and SFTP.

SFTP, its authenticity is checked using stored certificates. Normally, the devices from solvimus GmbH are coming with an individual, self-signed certificate upon delivery. This certificate is usually classified as untrusted by your PC. Therefore, a security prompt with information about the device’s certificate is displayed.
When a connection is established to a specific device with SSH, its authenticity is checked using stored certifi- cates. Normally, the devices from solvimus GmbH are coming with an individual, self-signed certificate upon delivery. This certificate is usually classified as untrusted by your PC. Therefore, a security prompt with infor- mation about the device’s certificate is displayed.
4 Web-based front end 4.1 General information Many products from solvimus GmbH, especially data concentrators and gateways for smart metering, are com- ing with an integrated web server and provide a website for the configuration. The devices can be configured easily and in a user-friendly manner via this website.
Details are given in Section 4.11. The solvimus GmbH provides a manual in PDF format on the homepage. The link can be accessed by clicking the button Help (see Figure 16, bottom right).
Change password button when the admin user is logged in. If the administrator password is lost, the device can only be reset to factory defaults by solvimus GmbH as file access on the device is limited for safety reasons. When resetting, all configuration data and meter data are lost.
Using the Update firmware button opens a file selection dialogue as well. An update file can be selected here. The solvimus GmbH provides updates as *. enc files on a regular basis. These files can then be uploaded to the device. After successfully uploading them, the update process is started automatically and the device is then restarted.
In addition, the parameter M-Bus request mode in the Configuration tab can be used to explicitly define the requested data before the actual readout. Devices from solvimus GmbH can send a so-called global readout request to the meter before the actual request. A SND_UD is sent to the meter for this purpose. The user data then consists of only one or two characters.
The FCB mechanism according to IEC 60870-5-2 is used by the readout sequence. The solvimus GmbH calls this process „multipaging“. In order to request possibly existing telegrams from the meter, the master has to toggle the FCB with each new request REQ_UD2.
The other side hase then to respond within this very short time to keep the receiver active, otherwise it will be switched off again. The devices of solvimus GmbH are intended for unidirectional operation and are therefore only used to receive meter data.
Using the client-server model, in the case of data push the device from solvimus GmbH is the client and the third-party system is the server. In the case of the data pull, the device from solvimus GmbH is the server and the third-party system is the client.
Several CSV formats are available for transmission of raw frames. CSV is a table-like file format which uses a character, solvimus GmbH uses a semicolon „;“ (in CSV-10 a comma), for separating numerical values and texts (columns) from each other. This allows easy processing or viewing e. g. in Excel.

The devices from solvimus GmbH are using certificates in the PEM format (RFC 7468). In the case of server-side authentication, the device from solvimus GmbH checks if the server is trustworthy. This requires an installed certificate (public key) issued by the certification authority to be relied upon, and who has signed the certificate of the server.
(read, write or execute). In addition to the user root, the devices from solvimus GmbH are coming with the user admin. This user has read and write access to the partitions app and ext and can execute files there. For the operator, admin is the user who can completely configure the device.

• xsltproc: Executing XSL transformations solcmd command interpreter Due to the system access rights for users, solvimus GmbH adds a command interpreter solcmd. It offers special application functions via the command line. The interpreter can be called with various parameters and thus provides access to the application and allows controlling it.

In the EN 13757-3 standard, media types, measurement types (measurement value descriptions) and units and are predefined. The devices from solvimus GmbH are using it for allowing a uniform data display. The following table contains the predefined values for the medium:...
