简介

CPs with an internal microprocessor

• Protocol software executes on the CP
• Free PC resources for applications
• Suitable for comprehensive applications
• Recommended for applications with HMI systems which have high performance requirements, e.g. WinCC
• Recommended for large systems (eight stations or more, e.g. SIMATIC)
• Constant communication throughput
• Can be used for redundant communication
• Use for PROFINET IO real-time applications (RT, IRT with CP 1616/CP 1604)
• Time synchronization

CPs without internal microprocessor

• Protocol software executes on the PG/PC
• PC resources are divided between communications and applications
• Suitable for less comprehensive applications
• Recommended for smaller applications (up to eight stations, e.g. SIMATIC)
• Communications performance depends on PC resources and PC loading

CPs with integral switch

• Connection of additional field devices to the Industrial Ethernet by means of additional switch ports
• Switch mode possible via external power supply even with PC switched off

Configuration for SIMATIC NET version V12 or higher

STEP 7 V12 or higher is used for PC configuration. The STEP 7 software is included in the scope of delivery of the SIMATIC NET products. A STEP 7 license is not required for PC configuration.
