Product details

The 6AG1215-1HG31-4XB0 is a SIPLUS variant of the Siemens S7-1200 CPU 1215C, designed for extended ambient temperature and harsh environments. This CPU supports the full TIA Portal programming suite with FBD, LAD, and SCL languages, so it integrates into existing S7-1200 projects without rework. It includes 4 Mbyte program memory, 1 024 byte input and output image each, and 480 h backup time.

Networking and fieldbus

The CPU carries a PROFINET interface with autocrossing and autonegotiation, plus support for PROFIBUS (as client and server), MODBUS TCP, AS-Interface, and Ethernet UDP. That covers most mixed-vendor line integrations, but PROFIsafe is not supported – safety tasks require a separate F-CPU.

Frequently asked questions

What programming languages does the 6AG1215-1HG31-4XB0 support?

It supports FBD (function block diagram), LAD (ladder logic), and SCL (structured control language), verified in the specification.

What networking protocols does this CPU support?

PROFINET (with autocrossing), PROFIBUS (client and server), MODBUS TCP, AS-Interface, and UDP. It does not support PROFIsafe.

What is the operating temperature range?

-40 °C to +70 °C, designed for extended industrial environments.
