Communication is built in for Modbus TCP, OPC UA Server, SNMP, LLDP, and TCP/IP; PROFIBUS is not on the CPU itself and requires either a CM 1243-5 master or CM 1242-5 slave module, with PROFIsafe handled through that path. Forcing is permitted on peripheral inputs and outputs that are not part of the fail-safe image, which is the standard SAT-tool posture for this class. ## Operating envelope Operating temperature spans -40 °C to 70 °C, which is wide enough to drop into an unheated outdoor enclosure or a high-density cabinet without forcing an early derate review. The I²t figure of 0.5 A²·s is on the output-stage record, and that is the number selectivity coordination gets sized against rather than any headline current. Footprint is 110 mm wide by 100 mm tall by 75 mm deep — modest on the DIN rail, so the panel layout driver here is wiring room and clearance, not the CPU envelope itself.","metaTitle":"Siemens 6ES7214-1AF40-0XB0 CPU, 24 V DC, failsafe","metaDescription":"Siemens 6ES7214-1AF40-0XB0 SIMATIC CPU with LAD/FBD/SCL, failsafe in LAD/FBD, Modbus TCP and OPC UA Server.
