Hi together,

welcome to our IOT2050 support forum. Please read this guide carefully before reaching out with a new topic to the forum. Most enquiries have already been answered once in the forum. In this guide we will link the most relevant articles and give you an overview of the most common hurdles when setting up and working with the IOT2050.

NEWS: We released two new application examples (also for our new IOT2050SM!) on our SIMATICmeetsLinux GitHub Repository - Check them out!

• IOT2050SM-Energy-Data-Management: This application describes how to collect and manage energy data on an IOT2050SM using a compatible Energy Meter 1238. The performance data will be collected, pre-processed and forwarded to a SCADA system using MQTT.
• IOT2050-Interface-Examples: Collection of example codes demonstrating how to interface with various GPIO's using the MRAA library on the SIMATIC IOT2050.

Information about the IOT2050:

• Overview about FS states of IOT2050: The functional state (FS) indicates in which status the device is delivered. This article also gives you an overview of what OS-versions are required on your device
• Guide: Firmware Update to V1.4.X: The latest firmware update includes the fix to the reboot issue. We recommend updating your devices.

Operating System Options:

For the IOT2050 we are offering two supported OS options: Example Image and SIMATIC Industrial OS (IndOS). IOT2050 Advanced versions are delivered with a pre-installed version of IndOS on the eMMC. What OS is suitable for you?

• The SIMATIC Industrial OS (IndOS) is a Debian-based Linux system and is optimized for industrial applications with features like hardened security. It's recommended for production environments where stability and security are critical. The OS does not include a GUI by default. Please follow our guide on How to setup Industrial OS on the IOT2050 Advanced.
• The IOT2050 Example Image is a Debian-based Linux system and provides additional flexibility for development purposes - including tools like SDKs for cross-compilation and support for various programming languages. It is ideal for testing, prototyping and scenarios requiring custom configurations not available in IndOS. Please follow our guide on How to setup IOT2050 with Example Image.
• You can also build your own Operating System out of our meta-iot2050 GitHub-Repository

How to connect to your IOT2050?

• Display Port cable and Keyboard: The easiest way is to connect your IOT2050 with a Display Port cable to a monitor and to control it via a keyboard (Important: Passive signal adapters like passive DP-to-HDMI-adapters are not supported! We recommend using default DP cables).
• Serial Connection via UART Cable: The serial connection must be configured with the correct COM-port, Speed 115200 and a suitable UART cable (Recommended: FTDI TTL-232R-3V3 USB to UART). The Serial connection also allows you to access the uboot-shell
• Ethernet connection: When using the IOT2050 Example Image you can directly connect to the X1P1 port of the IOT2050 (pre-configured to IP 192.168.200.1 - for older versions <V1.1.1 it is pre-configured on X1P2). Please make sure your Engineering Station is in the same subnet as the IOT2050 (Important: IndOS has no IP address configured by default - please choose another option for first commissioning). You cannot access the uboot shell with the ethernet-connection.

Application Examples:

You can find different application examples for the IOT2050 on our SIMATICmeetsLinux GitHub Repository:

• NodeRed Data Collector: Example how to read data from a S7-1500 with the IOT2050 via S7, Modbus TCP and OPC UA and store the data in a local database on the IOT2050 using node-red
• NodeRed OPCUA Server: The application describes how data can be stored, structured and read out on a local OPC UA server built with Node-Red. The data used are read out from an S7 PLC using different protocols.
• Serial Modbus RTU: This application shows two ways to exchange data via a serial port between PC (Windows/Linux) and the IOT2050. In the first example a pure serial transmission is used, while in the second example the communication protocol Modbus RTU is used additionally.
• LoRa-Gateway mPCIe: Instructions for using the IOT2050 as a LoRa WAN (Long Range Wide Area Network) gateway with The Things Network as the network server. LoRa WAN Concentrator is realized with an mPCIe-card.
• IOT2050SM-Energy-Data-Management: This application describes how to collect and manage energy data on an IOT2050SM using a compatible Energy Meter 1238. The performance data will be collected, pre-processed and forwarded to a SCADA system using MQTT.
• IOT2050-Interface-Examples: Collection of example codes demonstrating how to interface with various GPIO's using the MRAA library on the SIMATIC IOT2050.
• and a lot more!

You will also find our SIMATIC IOT2050 Interfaces Example (will be published soon!) with a huge Collection of example codes demonstrating how to interface with various GPIO's using the MRAA library on the SIMATIC IOT2050.

Status LED on IOT2050 (using the Example Image):

The IOT2050 variants have four different Status LEDs: PWR, STAT, USER1 & USER2

• PWR (Power) LED:
  • Green: Indicates that the IOT is in operation.
• STAT (Status) LED:
  • Green: System is starting up.
  • Green blinking: The operating system is running.
  • Red: System startup failed or no valid operating system is detected.
  • Red blinking: The operating system crashed.
• USER1 and USER2 LED: These are user-programmable LEDs and can be set to indicate different statuses (Red, Green, Orange) or functions as defined by the user.

A running operating system contains a green PWR-LED and a green-blinking STAT-LED.
