Removing and inserting modules during operation

Introduction
ET 200S supports the removal and insertion of modules during operation (RUN mode). The
ET 200S remains in RUN mode when an electronic module is removed. The protective
conductor connections of the ET 200S are not interrupted.
Rules
• You cannot remove and insert modules during operation unless the corresponding
• You can remove and insert modules during operation with IM151-1 BASIC, IM151-1
• If one module is missing (gap) and the ET 200S POWER ON is switched, the station will
• The removal and insertion of modules affects the cycle synchronization (constant bus
• When replacing more than one module, make sure that only one gap occurs.
