The CPUs 014 and 015PN are based in the technology Speed7 of the subsidiary Profichip. This chip increases considerably the already fast time of access of his predecessor. The powerful back bus of 48 Mbit/s, in conjunction with the modules ETS, offers time of conmutación of +-1 s. The CPUs SLIO are programmable with the code of Step7, that helps him to keep his know-how. The simple and amicable configuration of the CPU can realizar through the VIPA Speed7, as well as with Simatic Manager and TIA Portal. Through his by heart intelligent management and only, is possible to expand the memory of the CPU until the 512 kB during the operation (according to the version). The CPU bears until 64 modules SLIO in his central frame.
The controllers come instrumented of form predetermined with an interface RJ45 Ethernet for the communication PG / OP, an interface PtP for protocols series and MPI. A master/slave Profibus DP and Profinet also are available.
