Product details

SIPLUS S7-1200 CPU 1214C, order code 6AG1214-1HG31-2XB0, is the ruggedized version of Siemens' compact PLC for extended temperature ranges. Rated for -40 to 70 °C, it handles unheated cabinets or direct outdoor installation. Accepts 24 V DC supply from 20.4 V to 28.8 V, so it rides through line dips without browning out.

Panel fit and fieldbus

Dimensions: 110 x 100 x 75 mm (W/H/D). Mounts on standard DIN rail; front-facing PROFINET port with autocrossing and autonegotiation. Also supports Modbus TCP, UDP, PROFIBUS, and AS-Interface. Three programming languages onboard: FBD, LAD, SCL.

Memory and backup

Integrated work memory of 4 Mbyte – enough for medium-scale logic, PID control, and motion sequences. Backup time of 480 h typical keeps program and retentive data through a weekend outage. Forcing allowed for commissioning.

Frequently asked questions

What programming languages does this CPU support?

It supports FBD, LAD, and SCL – all three ladder, functional block, and structured text are built in.

What communication interfaces are available?

PROFINET with autocrossing, Modbus TCP, UDP, PROFIBUS, and AS-Interface. Also includes remote forcing and isolated signal handling.

What is the operating temperature range?

-40 °C to 70 °C, making it suitable for cold storage, outdoor cabinets, or high-heat environments.
