It provides a 1 x 20 mA current-loop interface (TTY) for OP\/PG\/PC and SINEC L1, accessed via a 15‑pin Cannon socket, and supports V.24 communications through RS-232C and RS-422\/485 interfaces for programming devices or terminals. The module also includes a dedicated slot for a MC 374 memory card (Flash EPROM) to store programs or data, enabling persistence between power cycles. As part of the S5-115U family, the 6ES5945-7UA13 serves as a CPU\/central control board that pairs substantial RAM with expandable I\/O connectivity, a configuration commonly encountered in legacy Siemens S5 installations and suitable for repair, maintenance, or continuation of older automation lines. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268521447658,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6es5945-7ua13-interface-module-for-s5-plc","provider":"GTG Hardware","version":"1.0","type":"link"}
