Siemens 6ES5700-0LB11 is a CR 700-0LB mounting rack for the SIMATIC S5 central controller S5-115U, designed to house multiple modules in a single chassis. It provides six free slots for central and decentralized I/O modules, enabling expansion of the S5-115U system. Listed in Siemens- and third-party catalogs as a CR 700-0LB family part, 6ES5700-0LB11 serves as a legacy SIMATIC S5 backplane carrier rather than a standalone control module.
