Product information
Overview
Applications
- Isochronous operation: Supports isochronous mode via the PROFIBUS DP or PROFINET interface, alternatively, using OB 61.
- PROFINET IO communication: Supports PROFINET IO Controller and PROFINET IO device functionality, including simultaneous operation.
Key Features
- Work memory: Integrated 384 kbyte work memory; not expandable.
- Communication interfaces: 1st interface: MPI/PROFIBUS DP at up to 12 Mbit/s. 2nd interface: Ethernet PROFINET with 2-port RJ45 switch.
- PROFINET communication: Supports PROFINET IO Controller and PROFINET IO device functionality simultaneously, with transmission rates up to 100 Mbit/s.
- Power supply: Rated supply voltage: 24 V DC; permissible range: 20.4 V to 28.8 V DC.
- Programming and memory card: STEP 7 V5.5 or higher is supported. Plug-in MMC load memory is supported up to 8 Mbyte; a Micro Memory Card is required.
