It carries 64 function modules (FM) capacity, though that number is limited by the number of slots and connections available in the rack — so the real limit depends on your backplane and the modules you already have seated. It handles 244 bytes of inputs and 244 bytes of outputs. Programming languages include CFC, FBD, LAD, SCL, STL, GRAPH, and HiGraph. Physical dimensions are 50 mm wide, 290 mm tall, and 219 mm deep — that's a standard S7-400 slot width, so it slides into the same rack as any other 400-series CPU without panel rework. ## Programming and communication Programming is done via STEP 7 (V5.x or TIA Portal depending on your version). The CPU supports MPI, RS 485, and S7 routing — the latter only when the interface is active. It can act as both a Modbus client and server via CP modules and loadable FBs. For networking, it handles up to 10 connections via CP modules, and up to 64 connections via CP for LAN or PtP — again limited by the number of slots and connections. One of those overall 64 connections is reserved for PG and OP, so plan your HMI and programming access accordingly. The CPU supports forcing, single-step debugging, and adjustable resolution down to 1 ms. ## Memory and data handling The maximum size for data blocks is 16 kbytes. The preset retentivity is set to 'No retentivity', so if you need data to survive a power cycle, you'll need to configure retentive areas explicitly. SYNC/FREEZE functions are supported, which is useful for synchronizing inputs across multiple modules in a high-speed application.","metaTitle":"Siemens 6ES7416-3XL00-0AB0 S7-400 CPU, 64 FM, 244 byte I/O","metaDescription":"Siemens S7-400 CPU 416-3XL00 with 64 FM capacity (limited by slots/connections), 244 byte inputs/outputs, CFC/FBD/LAD/SCL/STL support.
