It gives the CPU a second Ethernet interface with DCP, NTP, TCP/IP, SNMP v1, and a stateful inspection firewall. Static IP routing is supported, but dynamic routing protocols (OSPF, RIP, BGP) are not — so this module is for deterministic plant networks, not WAN edge routing. The interface runs at 10 to 1000 Mbit/s; IP routing throughput is limited to 1 Mbps, which aligns with infrequent configuration traffic rather than bulk data transfer. Configuration requires STEP 7 Professional V14 (TIA Portal) or later. Some features (like maximum connections per CPU) depend on the CPU type — verify the specific S7-1500 CPU's capability table before freezing the BOM.","metaTitle":"Siemens 6AG1543-1AX00-2XE0 Communication Module, S7-1500, IP","metaDescription":"Active production.

They are important components in a holistic industrial security concept. With this in mind, Siemens’ products and solutions undergo continuous development. Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action(e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. For more information about industrial security, visit http://www.siemens.com/industrialsecurity. To stay informed about product updates as they occur, sign up for a product-specific newsletter. For more information, visit http://support.automation.siemens.com.
