CPU slot briefing
The Siemens 6AG1214-1BE30-4XB0 S7-1200 CPU runs on 24 V with a permissible range of 20.4 V to 28.8 V and operates from -40 °C to 70 °C, making it suitable for unheated cabinets or outdoor enclosures. PROFINET is the only fieldbus interface – no MODBUS, no PROFIBUS, no PROFIsafe. If your line expects Modbus RTU or a second protocol, this variant forces an external gateway.
Memory and I/O map
Integrated 2 Mbyte load memory and bit memory address area max 8 kbyte; input and output process images are each 1 024 byte. Backup time 240 h typical; CPU not expandable.
Compliance and certification
Carries cULus, CE, and UL approval. That covers most North American and European spec requirements. Let me be transparent: the documentation pack I source with this includes the EU Declaration of Conformity and the UL report – genuine is genuine, same part, different passport.
