Configuration is done through STEP 7 V5.4 SP2 or higher, or TIA Portal V11. The first interface runs 10/100 Mbit/s, so plan your backbone accordingly. Ring redundancy is hardware-based, not managed-switch RSTP, so it works with other PROFINET devices in a ring. Security basics are covered: IP-based ACL (but not for PLC/routing), MIB support for SNMP monitoring, and lock-down of non-required services. No login logging, though.","metaTitle":"Siemens 6GK7343-1EX30-0XE0 CP 343-1 PROFINET, Ring Redundanc","metaDescription":"Siemens CP 343-1 PROFINET controller for S7-300.
