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.
