Siemens 6ES5788-7LA11 Simulator Module is a SIMATIC S5 simulation module intended for use with the S5-115U PC controller, also listed as 6ES57887LA11. This SIDE A unit provides 16 digital inputs and 16 digital outputs to emulate binary signals for testing and training in SIMATIC S5 applications. As part of the SIMATIC S5 family, it enables hardware-in-the-loop or offline I/O simulation to verify ladder logic or discrete control logic without full plant hardware, supporting typical S5-115U PC setups and related binary I/O scenarios in educational, service, or retrofitting contexts.
