Data communication<br />

MPI (multi-point-interface)<br />

Supported communication functions<br />

Controllers can be connected to the MPI<br />

by way of interfaces integrated in the<br />

CPUs of various automation systems<br />

(e.g. SIMATIC, SIMOTION); PCs/PGs can<br />

be connected to the MPI via integrated<br />

interface/communications processor.<br />

• Basic S7 communication<br />

Data are transmitted on an eventcontrolled<br />

basis by calling a<br />

communication block (SFC) in the CPU<br />

(basic S7 communication <strong>for</strong> S7-300,<br />

S7-400, C7).<br />

The advantage is that no space in user<br />

memory is required.<br />

The amount of user data per request<br />

may be up to 76 bytes (small amounts<br />

of data).<br />
