Monokot Server

Modern cross-platform data logger and OPC UA server for industrial automation and IoT

Industry 4.0

The server is based on the OPC UA communication stack and implements services for data access, history access, and methods needed to build modern automation systems. Ensure high reliability and safety while transferring your data


Cross-platform compatibility of OPC UA allows to deploy the server on Windows, Linux and macOS operating systems. Use the server for PC or Raspberry PI

Data Logger

Publish industrial data to IoT platforms via HTTP or store it in PostgreSQL, Oracle, MySQL, MS SQL, InfluxDB and MongoDB. The backlog mechanism will save data after a long loss of connection


Built-in engine for executing JavaScript code that is fully compatible with ECMAScript 5. Execute scripts periodically or as data changes. Process the server input data as you need

Multi-protocol communication

Industrial and IT Protocols

For communication with your field devices or services, the server supports most popular communications protocols:


    • Communication with Modbus TCP, RTU over TCP, RTU, ASCII devices (as master or slave)

    • S7 for Siemens PLCs and Sinamics via Ethernet

    • Simple Network Management Protocol (SNMPv1, SNMPv2c)

    • InfluxDB Connector (database fields as OPC variables)

    • IEC 60870-5-104 (TCP/IP client)

    • OPC UA Client (access to external OPC UA servers)

ECMAScript 5

Built-in JavaScript Engine

Run your scripts manually, periodically or when data changes. Scripts are a very powerful feature to convert input to output data:


    • Formula between tags

    • Mathematical functions

    • Conditional statements and cycles

    • Strings, numbers, date/time, arrays and etc

    • Re-use of code (modules)

    • Running SQL script, reading files, and other useful functions

    • Any simulation

Remote server management

Powerful and Easy

Monokot Server is simple and easy to use. Configure your devices and tags for a few minutes. Deploy the server on a target device and manage it remotely using your laptop or PC.


The built in user and role based security model allows you to configure data access rights.


Our server has an ability to read and write such server objects properties as device host, slave id, role permissions and etc via OPC UA.
