Product information
Overview
Key Features
- Central processing unit: CPU 317-2 DP with 1 024 kbyte integrated work memory and no work-memory expansion.
- MPI/DP and PROFIBUS DP: Two integrated RS 485 interfaces support combined MPI / PROFIBUS DP and PROFIBUS DP, with transmission rates up to 12 Mbit/s.
- PROFIBUS DP master capacity: The PROFIBUS DP master supports up to 124 DP devices and up to 8 devices activated or deactivated simultaneously.
- Load memory and backup: Plug-in MMC load memory is supported up to 8 Mbyte. Backup is maintenance-free through the MMC and works without a battery for program and data.
- Supply and installation data: Rated supply is 24 V DC, with a permissible range of 19.2 V to 28.8 V DC. Dimensions are 40 mm × 125 mm × 130 mm and approximate weight is 360 g.
