Extended Functions Compared with Version 5

S Reading and writing data in the FETCH/WRITE mode

The services FETCH and WRITE are supported for direct access to sy-

stem memory areas on the SIMATIC S7 PLC via ISO transport and and

ISO-on-TCP connections. The SIMATIC S7-300 with the CP 343-1 is

always the server (passive connection establishment), while the fetch or

write access (client functionality with active connection establishment)

originates from a SIMATIC S5 PLC or other device
