Programmable in LAD, FBD, and SCL. Integrated 4 Mbyte load memory with 480 h typical backup. Communication comes standard: PROFIBUS DP, MODBUS TCP (client/server), UDP, and AS-Interface. No extra module needed for the mill’s existing drive or valve-bank network—the CPU speaks all of them natively, which saves a slot and a license fee. Approvals include cULus, CE, FM, and CSA—so it passes the typical mill electrical audit without a waiver. The 24 V DC input is isolated, and the 0 to +10 V analog inputs can handle 2-wire sensors directly.","metaTitle":"Siemens 6ES7214-1AG31-0XB0 S7-1200 CPU, 24 V DC 20.4-28.8V","metaDescription":"S7-1200 CPU 1214C, 24 V DC supply (20.4-28.8 V), 70 °C max.
