Description
Sending data in blocks:
FB/SFB 12 BSEND sends data to a remote partner FB/SFB of the type BRCV
(FB/SFB 13). The data area to be transmitted is segmented. Each segment is sent
individually to the partner. The last segment is acknowledged by the partner as it is
received, independently of the calling up of the corresponding FB/SFB/FB BRCV.
With this type of data transfer, more data can be transported between the communi-
cations partners than is possible with all other communication FBs/SFBs for config-
ured S7 connections, namely 65534bytes.
Receiving data in blocks:
The FB/SFB 13 BRCV can receive data from a remote partner FB/SFB of the type
BSEND (FB/SFB 12). The parameter R_ID of both FB/SFBs must be identical. After
each received data segment an acknowledgement is sent to the partner FB/SFB and
the LEN parameter is updated.
Remote CPU read:
The FB/SFB 14 GET can be used to read data from a remote CPU. The respective
CPU must be in RUN mode or in STOP mode.
Remote CPU write:
The FB/SFB 15 PUT can be used to write data to a remote CPU. The respective
CPU may be in RUN mode or in STOP mode.
