The 6AG1511-1AK01-2AB0: SIPLUS variant of the S7-1500 CPU with an extended temperature range of -40°C to 70°C. Rated for 32 kbyte process image inputs and outputs. Supports PROFINET MRP as redundancy manager and client, IRT, and a built-in web server for diagnostic pages. The I2t rating of 0.34 A²·s defines the short-circuit energy withstand for protective coordination.
Extended temperature range (-40°C to 70°C)
Rated for continuous operation from -40°C to 70°C, this CPU suits installations in walk-in freezers, cold storage warehouses, or high-temperature cabinets without derating. The datasheet confirms the full temperature envelope; below 0°C, display legibility and dynamic content speed may be reduced, but the logic and fieldbus remain functional.
Network redundancy and fieldbus
MRP (Media Redundancy Protocol) is supported both as redundancy manager and client, enabling a ring topology with up to 50 devices. This is verifiable for validation documentation: the CPU's role as redundancy manager provides deterministic failover, which is auditable for GMP process control networks. IRT (Isochronous Real-Time) for equidistant cycle times is also supported.
Programming languages and engineering
Supports LAD, FBD, STL, SCL, and GRAPH as of STEP 7 V12 SP1. The hardware clock maintains time stamping across power cycles.
Power budget and I2t coordination
I2t rating of 0.34 A²·s is the short-circuit energy withstand. Use this limit for upstream protective device coordination.
