1)Notes on the FCs in FCs for an S7-300 and S7-400 S S7-300:

With older versions of the Ethernet CPs, the data length per job is restricted to <=240 bytes (applies up to block version V3.0 of AG_SEND / AG_RECV); with later versions, longer data records (up to 8192 bytes) can be transferred with FCs AG_LSEND or AG_LRECV.

With the latest versions of the Ethernet CPs, only FCs AG_SEND and

AG_RECV are used; due to a new and more efficient internal protocol, the data up to 8192 bytes can be transferred.

SS7-400:

With FCs AG_SEND / AG_RECV the data length per job is restricted to <=240 bytes.

Longer data records (up to 8192 bytes) can be transferred with FCs AG_LSEND or AG_LRECV.

Please check the manual /3/ of the S7-CP you are using for the data areas supported. You will find an overview of the versions of the FCs/FBs in the documentation and block history.

Application

The following diagram illustrates the use of the FCs described here for bi-directional data transfer on one configured connection.
