For Simatic S5 system applications, Siemens 6ES5788-7LC11 provides the function of a Simulator Module.
For replacement planning, its role is diagnostic and commissioning-oriented, helping technicians evaluate configured behavior while following the procedures and limitations defined for the exact module. The product remains part of the broader control and signal-handling arrangement.
In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. The documented module assignment should remain the basis for selection.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Existing connection and module records should guide replacement work.
