Product details

What the catalog row tells you

The 6ES7214-1AF40-0XB0: Programming languages supported out of the box are LAD, FBD, SCL, and GRAPH, with failsafe authoring available in LAD and FBD; DCP is supported and IRT is not, which matters where the panel builder was sold a synchronized motion story — that is not this CPU. 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.

Frequently asked questions

What is the listed DCP status for 6ES7214-1AF40-0XB0?

DCP is supported on this CPU.

What is the listed FBD status for 6ES7214-1AF40-0XB0?

FBD is supported, including failsafe authoring.

Does 6ES7214-1AF40-0XB0 support PROFIBUS?

Not on the CPU itself — PROFIBUS is added via a CM 1243-5 (master) or CM 1242-5 (slave) module.

What protocols are integrated on the CPU without an extra module?

Modbus TCP, OPC UA Server, SNMP, LLDP, and TCP/IP are integrated.
