MRP handles ring redundancy—up to 50 devices in the ring. MODBUS TCP rides the same port, and an RS485 interface is onboard for legacy drops. S7 routing is enabled, so you can reach across networks without an extra gateway. ## What Connects and How It Mounts DIN rail mount, 70 mm wide × 147 mm tall × 129 mm deep. Up to eight communication modules (PROFINET + PROFIBUS) fit on the side. RS485 is built in; DHCP comes switched off by default. LLDP and SNMP are ready for network discovery and management. HTTP and HTTPS both serve standard and user-defined pages—good for custom dashboards or recipe upload. ## Sourcing Reality: Not a Standard Shelf Part Rated -40 to 70 °C. controller with integrated optimization for valves is supported.","metaTitle":"Siemens 6AG1516-3AN00-2AB0 SIPLUS S7-1500 CPU, -40 to 70°C, PROFINET IRT","metaDescription":"SIPLUS variant of S7-1500 CPU 1516-3PN/DP.
