Freeport mode gives the user program full control of the telegram format for connecting non-Siemens serial instruments (scales, barcode readers, third-party controllers), while 3964(R) provides a fixed handshake protocol for point-to-point links to other SIMATIC controllers. At 19.2 kbit\/s and 1 200 m maximum cable length, throughput is adequate for polling or parameter read\/write but not for high-speed data acquisition.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSerial point-to-point links to third-party instrumentation, barcode scanners, or older SIMATIC S7-300\/S7-400\/S7-1500 stations, and USS-based polling of Siemens drives without a fieldbus network.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960655143195,"sku":"6ES7540-1AB00-0AA0","price":774.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7540-1ab00-0aa0-cm-ptp-rs422-485-ba.png?v=1789714777","url":"https:\/\/stoklink.com\/products\/siemens-6es7540-1ab00-0aa0-cm-ptp-rs422-485-ba","provider":"Stoklink","version":"1.0","type":"link"}
