5.3 Characteristic Data for SEND/RECEIVE Interface
The SEND/RECEIVE interface provides access to communication over TCP,
ISOonTCP, ISO transport, Email, and UDP connections.
The following characteristics are important:
Table 5-3
Characteristic
Explanation / Values
Number of SEND/RECEIVE connections S TCP connections: 1...64
1)
2)
S ISO-on-TCP connections 1 to 64
S ISO transport connections 1...64
S UDP connections (specified and free) configurable in total
1 to 64 (of those, up to 48 multicast mode)
S E-mail connection: 1
S Max. number of connections in total
(ISO transport + ISO-on-TCP
+ TCP+ UDP + E-mail) <= 64
Refer to the example in Section 5.1
1)
Note:
The flow control on TCP connections cannot control
permanent overload of the receiver. You should therefore
make sure that the processing capabilities of a receiving CP
are not permanently exceeded by the sender (approximately
150200 messages per second).
2)
TCP connections for FTP
Of the available to CP connections, a maximum of 20 TCP
connections can be configured / used with the ”Use FTP
protocol” option (see Section 5.7).
Maximum data length for AG_SEND and
AG_RECV blocks
AG_SEND and AG_RECV were shipped with predecessors of
the CP 443-1 Advanced and allow the transfer of data fields
with a length from 1 to 240 bytes. The version of the CP 443-1
Advanced described here continues to support these blocks.
Maximum data length for AG_LSEND
and AG_LRECV blocks
AG_LSEND and AG_LRECV allow the transfer of data fields
with the following lengths:
1. ISO-on-TCP, TCP, ISO Transport: 1 to 8192 bytes
2. UDP: 1 to 2048 bytes
3. E-mail (job header + user data): 1 to 2048 bytes
