Characteristic data of the SEND/RECEIVE interface, Fortsetzung

Characteristic

Explanation / values

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

Maximum data length for AG_SSEND

and AG_SRECV blocks

AG_SSEND and AG_SRECV allow the transfer of data fields

with the following lengths:
1. ISO-on-TCP, TCP, ISO Transport: 1 to 1452 bytes
2. UDP: 1 to 1452 bytes

Restrictions for UDP

S

Transfer is not confirmed

The transmission of UDP frames is unconfirmed, in other

words the loss of messages is not detected or displayed by

the send blocks (AG_SEND or AG_LSEND).

S

No reception of UDP broadcast

To avoid overload due to high broadcast load, the CP does

not allow reception of UDP broadcasts.
As an alternative, use the multicast function over a UDP

connection. This allows you to register the CP as a node in a

multicast group.

S

UDP frame buffering

Length of the frame buffer with buffering enabled:
2 KB
Note:

Following a buffer overflow, newly arriving frames are

discarded.

LAN interface - max. data field length

generated by CP per protocol data unit

S

sending
ISO transport, ISO-on-TCP, TCP:

−

400 bytes / TPDU with AG_SEND / AG_LSEND

−

1452 bytes / TPDU with AG_SSEND

S

receiving

−

ISO transport: 512 bytes / TPDU

−

ISO-on-TCP: 1452 bytes / TPDU

−

TCP: 1452  bytes / TPDU

5.3.2

Number of simultaneous SEND/RECEIVE calls

The number of SEND/RECEIVE calls that can be used at the same time is limited
both by the CPU and by the CP.

If the maximum number of simultaneous SEND/RECEIVE calls is exceeded, the
value 8302

H

 (no receive resources) is indicated in the STATUS of the surplus

SEND functions. This can, for example, happen when too many SEND/RECEIVE
calls are sent at the same time in OB1.
