Product details

Integrator's field note

The 6AG1214-1BG40-4XB0: This is the SIPLUS AC/DC/RLY CPU 1214C — the extended-temperature, conformal-coated variant of the standard S7-1200. The operating range spans -40 to 70°C, so it suits unheated enclosures or installations with thermal cycling. PROFINET with shared-device capability is onboard; MODBUS TCP and UDP are handled natively. For PROFIBUS, add a CM 1243-5 module. The 4 Mbyte load memory holds code and tags without a separate memory card. Backup retains the project for 480 h typical.

What makes this different from the standard CPU

The SIPLUS variant provides -40 to 70°C and conformal coating. Footprint is 110×100×75 mm.

Frequently asked questions

Does 6AG1214-1BG40-4XB0 support FBD, LAD, and SCL programming?

Yes. The CPU supports FBD, LAD, and SCL programming languages, so it integrates with existing Siemens TIA Portal projects using any of those methods.

What is the operating temperature range for this SIPLUS CPU?

It operates from -40°C to 70°C, making it suitable for unheated or extreme environment installations.

What communication protocols are supported without additional modules?

Onboard protocols include PROFINET (shared device), MODBUS TCP (client and server), UDP, and TCP/IP. For PROFIBUS you need the CM 1243-5 module.

How much load memory does this CPU have?

It has 4 Mbyte of integrated load memory for program code and data. A separate memory card is not required for typical applications.
