This manual provides essential information for the installation, configuration, and operation of the Siemens SIMATIC ET 200MP IM 155-5 PN HF interface module. Key tasks include connecting the 24V DC supply, establishing PROFINET communication, and configuring the module using STEP 7 software.
Product overview
The IM 155-5 PN HF interface module connects the ET 200MP distributed I/O system with PROFINET IO. It supports features such as isochronous real-time communication (IRT), media redundancy (MRP), and configuration control for flexible system setups.
Wiring
The module requires a 24V DC supply connected to the X80 terminal. PROFINET communication is established via RJ45 connectors. Ensure proper pin assignment as detailed in the manual to avoid connection errors.
Configuration control
Configuration control allows you to prepare your distributed I/O system for future extensions. By using control data record 196, you can configure the planned maximum configuration in advance and vary it later. The manual provides detailed procedures for configuring without empty slots, extending configurations, and combining different configurations.
Status and error displays
The module features LED indicators for quick diagnostics:
- RUN (green): Indicates the module status (e.g., starting up, exchanging data).
- ERROR (red): Indicates group errors or configuration issues.
- MAINT (yellow): Indicates maintenance requirements.
If an error occurs, evaluate the diagnostics buffer in the CPU or the module status in STEP 7.
Technical specifications
The module operates on 24V DC. It supports up to 30 modules downstream from the interface module. Detailed specifications regarding power consumption, address areas, and environmental conditions are provided in the technical data section.

Practical help
Common problems
Module not starting
Check if the 24V DC supply voltage is present and within the permissible range (20.4V - 28.8V).
Communication failure
Verify the PROFINET cable connection and ensure the IO controller is configured correctly.
Configuration error
Verify the control data record 196 and ensure the actual configuration matches the preset configuration.
Before use
- Verify 24V DC supply voltage
- Check PROFINET cable connections
- Ensure correct module slot assignment
- Configure the module in STEP 7
- Check for firmware updates
Specs in practice
- Supply voltage
- 24 V DC (SELV/PELV)
