The connection can then only be used for this mode; sending or receiving with the FCs AG_SEND/AG_LSEND or AG_RECV/AG_LRECV is then no longer possible.

The connection is established passively; in other words, only the partner station (SIMATIC S5 station, a PC station, or a non-SIMATIC station) can establish the connection. The setting is made automatically in the “General” tab and cannot be changed.

Notice

Remember that with this configuration on an S7-300, one connection resource (free connection for S7 functions) of the S7-300 CPU is used. CPU connection resources are also used, for example, by S7-300 CPs, in the FMS mode or by PGs and OPs. For more detailed information about the maximum connection resources, refer to /13/ and /7/.

SSIMATIC PC Station: FETCH ACTIVE / WRITE ACTIVE

If you select the FETCH ACTIVE or WRITE ACTIVE mode for the ISO transport connection, you can access the system areas on a SIMATIC S7 PLC or a SIMATIC S5 station from the PC station.

The connection establishment is active; in other words, the partner station must wait for connection establishment (passive connection establishment on the partner).
