It carries cULus and CE marks. Supports DCP, FBD, LAD, and SCL for programming. The CPU includes built-in forcing functionality and supports all standard S7-1200 data types including inputs/outputs, memory bits, DBs, distributed I/Os, timers, and counters. ## Protocols and connectivity Onboard protocols include MODBUS, OPC UA server, and UDP. PROFIBUS requires an external CM 1243-5 or CM 1242-5 module. No PROFIsafe, IRT, MRP, MRPD, or DHCP support. LLDP and SNMP are present. Connection capacity: up to 64 total connections (34 reserved), with separate pools for PG, HMI, S7, Open User, Web (up to 30), and OPC UA (up to 10). Analog input supports 0 to +10 V, adjustable. ## Physical dimensions and environment Measures 90 x 100 x 75 mm (W x H x D), standard S7-1200 footprint. Operating temperature -40 to 70 °C.","metaTitle":"Siemens 6ES7212-1BE40-0XB0 S7-1200 CPU, -40 to 70°C, DCP","metaDescription":"Siemens 6ES7212-1BE40-0XB0 S7-1200 CPU with DCP, MODBUS, OPC UA. -40 to 70°C, cULus, CE.
