Product details

CPU core and programming

The 6AG1214-1HG31-5XB0: Operating temperature spans -40 °C to 70 °C, covering cold storage and hot panel environments. Integrated 4 Mbyte memory holds user program and data; backup time is 480 h typical for retentive data.

Connectivity and I/O

Built-in PROFINET interface handles real-time automation comms. Also on board: PROFIBUS, Modbus TCP/IP, AS-Interface. Supports UDP, forcing, and autocrossing. Digital I/O address area: 1 024 byte inputs, 1 024 byte outputs. Analog input: 0 to +10 V, adjustable. Two-wire sensor thresholds: signal 0 at 5 V DC at 1 mA; signal 1 at 15 V DC at 2.5 mA.

Multi-protocol and control features

Functions as Modbus TCP client and server. PROFIsafe is not supported, so separate safety controller is required. PID controller integrated for closed-loop applications. Isolated voltage supply on the sensor side. Forcing and present monitoring are available as standard.

Physical dimensions

Compact footprint: 110 mm wide, 100 mm high, 75 mm deep — fits within standard S7-1200 cutout. No expansion slots available (non-expandable per the spec).

Frequently asked questions
