Standard CPU 317-2 DP, Delivery 07/03, L-Price: 2,800 EUR with two DP interfaces configurable as master or slave. Fail-safe CPU 317F-2 DP, Delivery 09/03, L-Price: 3,055 EUR Technology CPU 317T-2 DP, Delivery 12/03, L-Price: 4,170 EUR Integral technology/motion control functions according to PLCopen directly into the CPU; including fast I/O. The CPU 317 offers high processing performance for binary and floating-point arithmetic. The significantly faster processing of the user program results in shorter response times, in turn permitting shorter machine cycle rates. The greatly increased quantity framework provides optimum support for use of cost-reducing engineering tools such as SCL, programming of sequence chains with S7-Graph, etc. The increased block number range improves the portability and reuse of SIMATIC programs or parts of programs from other CPUs, e.g. from the CPU 318 or from smaller S7-300 CPUs up to the largest S7-400 CPU. The CPU 317 offers an ideal platform for simple, software-implemented technological tasks, e.g. Easy Motion Control (reloadable runtime SW options). The CPU 317 is a CPU with a large program memory and quantity fr
