CPU 316-2DP — end-of-life reality for a mid-range S7-300
The 6ES7316-2AG00-0AB0: Rated at 24 VDC with a typical power loss of 10 W, this CPU is built for the standard S7-300 form factor — 80 mm wide, 125 mm tall, 130 mm deep — and mounts directly on the DIN rail in the same rack as I/O and function modules.
Programming and function module support
The CPU is programmed via STEP 7 V5.0 and supports LAD, FBD, STL, SCL, GRAPH, and HiGraph® — covering ladder, function block, statement list, structured text, and sequential control. CFC (Continuous Function Chart) is also supported, making it suitable for process-oriented programming. It handles up to 8 function modules (FM) and 8 dynamic blocks, with 4 static blocks. The command set includes binary logic, arithmetic, comparison, shift, rotate, and block-call operations, with a configurable cycle time between 1 ms and 6,000 ms.
