Key Product Information

Operating Role and Station Integration

The interface module forms the communication head of an ET 200SP station. It exchanges cyclic I/O data with a PROFINET controller and coordinates the configured station modules. For a replacement project, verify the BusAdapter type, the number and order of I/O modules, supported feature set, firmware requirements and controller project before removal of the installed unit.

Applications

• ET 200SP distributed I/O stations on PROFINET networks
• Production-line and machine control cabinet maintenance
• Replacement planning for an installed IM 155-6 PN High Feature module
• Station expansion review where module capacity and timing must be checked
• Migration projects requiring lifecycle and successor evaluation

Compatibility and Revision Notice
