1. Challenge

Industrial production lines like food processing, chemical plants, plastics extrusion, and metal treatment require continuous, high-precision temperature monitoring across multiple zones. Curing ovens, cooling tunnels, extrusion dies, and chemical reactors all demand accurate, real-time temperature data to ensure product quality and process safety.

Integrators and Machine Builders need a fast, open, and cost-effective approach that integrates seamlessly with modern data analysis tools.

2. Solution

La ADDI-DATA MSX-E3211 module provides 16 channels of industrial-grade temperature measurement over Ethernet. Available in two versions, the module covers virtually any industrial temperature monitoring scenario:

• RTD (PT100/PT500/PT1000) for high-precision applications
• Thermocouple (Type B/E/J/K/N/R/S/T) for wide temperature ranges

Combined with our open-source Python SOAP API, users go from unboxing to live data acquisition in under 5 minutes without proprietary software required.

Key features:

• 16 temperature channels per module
• RTD and Thermocouple versions available
• Industrial Ethernet connectivity (SOAP over HTTP)
• Open Python API
• Auto-detection of sensor type (RTD vs TC)
• Compatible with the full Python ecosystem: matplotlib, pandas, CSV, cloud APIs

3. Five-Minute Quick Start

Step 1: Configure MSX-E

Connect the MSX-E3211 to your Ethernet network. The module ships with a default IP address. Configure it to match your network using the ADDI-DATA Config Tools.

1. Automatic search for the MSX-E systems

6. ConfigTools for acquisition systems with inductive transducers

Step 2: Install Zeep for SOAP

Install the Python SOAP client library:

pip install zeep

Step 3: First Reading

Run the following Python code to read temperatures from all 16 channels:

"""Sample: Temperature polling on the MSX-E 3211.
Demonstrates:
  - Querying the number of temperature channels
  - Auto-detecting sensor class (RTD, TC, or NTC) per channel
  - Configuring channels with appropriate types
  - Starting auto-refresh acquisition
  - Polling temperature values at regular intervals
  - Stopping acquisition
Works with both thermocouple (TC) and RTD versions of the MSX-E 3211.

Step 4: Live Dashboard

Get below our Live Dashboard sample on Github:

• ADDI-DATA | MSX-E Samples

Install matplotlib and run the dashboard sample for real-time visualization:

pip install matplotlib
python sample_temperature_dashboard.py

A live chart window opens showing all 16 temperature channels updating in real time. Close the window to stop acquisition.

Step 5: Data Logging

Get below our Live Dashboard sample on Github:

• ADDI-DATA | MSX-E Samples

Log all channels to CSV for analysis in Excel, pandas, or any BI tool:

python sample_temperature_csv_logger.py

Outputs a timestamped CSV file with one row per reading and one column per channel, ready for import into any analysis tool.

4. Architecture

The system architecture is simple and modular:

Multiple MSX-E 3211 modules can be connected to the same network. Each module is addressed by its IP address. The Python API handles SOAP communication transparently.

5. API Highlights

The Python API is designed for simplicity. Here are the key operations:

• configure_all_channels(): Auto-detect RTD or TC and configure all 16 channels in one call
• auto_refresh_start() / get_values() / stop(): Continuous acquisition with configurable refresh rate
• temperature_diagnostic(): Check sensor health per channel
• print_channel_configuration(): Display current configuration at a glance

All operations raise MSXEError with clear error codes on failure. The API supports both RTD and Thermocouple versions with the same code.
