It carries 1 MB of integrated load memory and addresses up to 1 024 bytes each of inputs and outputs—enough for a medium-sized machine with local and distributed I/O. The CPU supports FBD, LAD, and SCL programming, forcing, voltage monitoring, and a 480-hour backup time. ## Fieldbus and connectivity layout Out of the box, the CPU supports MODBUS (as client/server), UDP, TCP/IP, and PROFIBUS. AS-Interface is also supported. The PROFIBUS port is isolated; an additional PROFIsafe module is not supported on this CPU. For panel integration, the 90 x 100 x 75 mm footprint mounts on standard DIN rail or screw tabs, with the backplane power budget sized for two additional signal modules. Programming via TIA Portal covers all three languages (FBD, LAD, SCL). The integrated Ethernet port supports autocrossing, so no crossover cable for direct PC connection.","metaTitle":"Siemens 6ES7212-1BE31-0XB0 S7-1200 CPU, 24VDC, -40-70°C","metaDescription":"Siemens S7-1200 CPU 6ES7212-1BE31-0XB0, DC supply 20.4-28.8V, 1MB memory, supports FBD/LAD/SCL, MODBUS, PROFIBUS. cULus/CE/UL/CSA/FM.
