■ Overview
• PROFINET IO controller to operate distributed I/Os on
PROFINET
• Component based Automation (CBA) on PROFINET
• PROFINET proxy for intelligent devices on PROFIBUS DP in
Component Based Automation (CBA)
• CPU with PLC functionality equivalent to S7-315-2 PN/DP,
provides distributed intelligence for preprocessing
• Interface module to exchange preprocessed I/O data from
ET 200pro with a higher-level master through PROFIBUS DP
• Fast, simple and end-to-end programming of a system with
modular programs via STEP 7
Micro Memory Card required for operation of CPU.
