# Introduction

> [!WARNING]
> Note:
> 
> This module is available from **N3uron** version **1.22.0**.

The [**IEC 60870-5-104 Server**](https://n3uron.com/iiot-platform-modules/iec-104-server/) module enables **N3uron** to expose data to external monitoring and control systems and other operational applications using the **IEC 104 protocol** — including SCADA systems, utility control centers, dispatching systems, and other utility-grade platforms. You can create and configure one or multiple **IEC 104 servers** (slave/outstation) to publish data gathered through other **N3uron** modules, such as the [OPC UA Client](/v122/docs/opc-ua-client), [Modbus Client](/v122/docs/modbus-client), [DNP Client](/v122/docs/dnp-client), [OPC DA Client](/v122/docs/opc-da-client), [REST API Client](/v122/docs/rest-api-client-introduction), [MQTT Client](/v122/docs/mqtt-client), [Siemens Client](/v122/docs/siemens-client), and other data acquisition and edge computing modules available within the platform. Communication is performed over TCP/IP as defined by IEC 60870-5-104.

Some of the key features of the module include:

- Unsolicited reporting (event-driven) or Interrogation-based reporting (General/Group).
- Direct Execute for write operations.
- Monitoring Information Objects (read): Single point, Double point, Normalized value (16-bit), Scaled value (16-bit), Bit string (32-bit), Floating point (32-bit IEEE-754).
- Control Information Objects (write): Single point command, Double point command, Normalized value command (16-bit), Scaled value command (16-bit), Bit string command (32-bit), Floating-point command (32-bit).
- Unlimited Servers.
- Unlimited Devices.
- Unlimited Information Objects.
