Product details

PROFINET connected, ruggedized for thermal extremes

The 6AG1212-1BD30-4XB0 is a SIPLUS variant of the Siemens S7-1200 CPU, built for a -40 to 70°C operating range and a 20.4 to 28.8 V DC supply. It supports LAD, FBD, and SCL programming languages and communicates via PROFINET (no Modbus or PROFIBUS). Integrated 1 MB work memory and a typical 240 h backup for the real-time clock mean program and RTC data persist through extended power-offs. The process image is 1 024 bytes each for inputs and outputs.

Memory, compliance, and sourcing

Rated for cULus, UL, and CE mark, this CPU carries the approvals expected for a global panel build.

Mounting dimensions and connection notes

Width 90 mm, height 100 mm, depth 75 mm — fits the standard S7-1200 footprint. DIN-rail mount, same profile as the basic CPUs. PROFINET interface with autonegotiation and autocrossing (MDI/MDIX). No fieldbus expansion available (AS-Interface, PROFIBUS not supported onboard). Ethernet connection is TCP/IP. Forcing and full program upload/download supported. Remanent data uses the integral EEPROM for maintenance-free retention.

Frequently asked questions

Does the 6AG1212-1BD30-4XB0 support Modbus?

No. It has no Modbus interface; the only onboard communication is PROFINET (TCP/IP). For Modbus RTU or TCP, an external gateway is required.

What is the backup time for the real-time clock?

Typical 240 hours. This capacitor-backed hold time ensures the clock persists through weekend outages.
