Siemens 6ES7511-1AK02-0AB0 Central Processing Unit

Overview

6ES7511-1AK02-0AB0 is a Siemens SIMATIC S7-1500 CPU 1511-1 PN central processing unit, configured and programmed through the TIA Portal engineering platform. The CPU features 150 KB of program work memory and 1 MB of data memory. In distributed mode, the minimum OB 6x cycle time can reach 625 µs, while the minimum cycle time in centralized mode is 1 ms. Operation requires a SIMATIC memory card.

Material Note: This product contains substances such as lead oxide and bisphenol A, with a mass proportion of >0.1%.

Core Features

PROFINET IRT Communication: The first interface of the 6ES7511-1AK02-0AB0 is PROFINET IRT, supporting functions such as MRP (Media Redundancy Protocol) for building redundant ring networks.

Engineering Configuration: The 6ES7511-1AK02-0AB0 can be configured through STEP 7 TIA Portal. The model requires TIA Portal V17 (corresponding to firmware V2.9) or higher. 

Data Block (DB) Number Range: The DB number range is 1 to 60,999, with 1 to 59,999 available for user programs and 60,000 to 60,999 reserved for the system. For DBs using absolute addressing, the maximum capacity is 64 KB.
