Rev. 00/07 5-59
Type
Single job
The order types SEND and RECEIVE, send and receive the messages in TCP protokolls as
reference data without any additional Header.
With the type single order, the message data exchange should consist of
defined, fixed message lengths!
This means that the Default Parameter "-1" cannot be used in the length data
in the FB RECEIVE!
TRADA without Response
The reference data is preceded by a Header in the order type SEND (Header set-up see Chap.
4.3.5.2). A message sent from the remote station will be examined at the Header with the
order type RECEIVE and the reference data will be transferred to the control according to
the transferred length.
Different telegram lengths are possible with the type TRADE!
The Default Parameter "-1" is permissable in the length data in FB
RECEIVE!
