SIPLUS S7-1200 — built for the cold (and the heat)
The 6AG1212-1BE40-4XB0: Rated for -40 to 70°C ambient, this SIPLUS CPU 1212C lives where the standard 6ES7212-1BE40-0XB0 would step outside its spec. Same 24 V supply (20.4-28.8 V), same PROFINET port, same 1 Mbyte work memory — the only change is the environmental envelope. If your line runs in a cold storage warehouse, an outdoor pumping skid, or a desert solar field, this CPU fits without rewiring or software rework. The extended temperature range is the reason to pick this order code over the standard variant.
How it compares to the standard 6ES7212-1BE40-0XB0
Programming languages (LAD, FBD, SCL), communication protocols (PROFINET, MODBUS TCP/IP, UDP), and memory size (1 Mbyte) are identical to the standard CPU 1212C. Temperature range extended to -40 to 70°C. Swap it into a panel designed for the standard part — same 90 x 100 x 75 mm footprint, same terminal assignments, same PROFINET wiring. No panel layout changes needed.
Mounting and integration
Standard DIN rail mount, 90 mm wide x 100 mm high x 75 mm deep. Supply range 20.4 to 28.8 V DC. PROFINET interface with autocrossing and shared device support. Backplane power budget is per the standard 1212C — no additional load. Backup time 480 h typical for the real-time clock and retain memory. Web server enabled for diagnostics. Programming via TIA Portal using LAD, FBD, or SCL.
