Product details

The 6AG1516-3AN02-2AB0: Process image handles 32 kbyte inputs and 32 kbyte outputs — enough for a medium distributed I/O layout with local periphery. Supports LAD, FBD, SCL, STL, and GRAPH programming languages, matching the standard S7-1500 toolchain, so no retraining needed. Built-in MRP redundancy manager functionality (max 50 devices in the ring) and MODBUS TCP over the same PROFINET ports — no additional communication module required for either.

Fit comparison vs standard 6ES7516-3AN01-0AB0

The 6ES7516-3AN01-0AB0 carries a standard 0–60°C operating range and no conformal coating. The SIPLUS version extends cold-end by 10°C and hot-end by 10°C, and adds coating for condensation resistance. All other features — 32 kbyte I/O image, MRP manager, MODBUS TCP, 70 mm width — are identical.
