For Simatic S7 system applications, Siemens 6ES7142-1BD20-1XB0 provides the function of a Basic Module.
For replacement planning, this component performs the specialized system function identified by its product designation within the associated automation platform. Its exact capabilities are determined by the installed configuration and product revision. The documented module assignment should remain the basis for selection.
Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. Selection should account for the intended surrounding hardware configuration.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. The surrounding rack and module arrangement should be reviewed before installation.
