You must, however, make sure that the areas defined by the parameters
SD_1/SD_1...SD_4 and RD_1/RD_1...RD_4 (at the corresponding
partner FB/SFB URCV) agree in Number, Length and Data type.
The parameter R_ID must be identical at both FB/SFBs. Successful com-
pletion of the transmission is indicated by the status parameter DONE
having the logical value 1.
Error information
ERROR STATUS
(decimal)
Description
0 11 Warning: the new task is not active, since the previous task
has not completed.
0 25 Communications initiated. The task is being processed.
1 1 Communication failures, e.g.
n Connection parameters not loaded (local or remote)
n Connection interrupted (e.g. cable, CPU turned off, CP
in STOP)
1 4 Error in transmission range pointers SD_i with respect to
the length or the data type.
1 10 Access to local application memory not possible (e.g.
access to deleted DB).
1 12 The call to the FB/SFB
n contains an instance DB that does not belong to the
FB/SFB 8
n contains a global DB instead of an instance DB
n could not locate an instance DB
(load a new instance DB from the PG)
1 18 R_ID already exists in the connection ID.
1 20 Not enough memory.
To ensure the data consistency is not compromised, can the currently used transmission
ranges SD_i be described again only if the current job is completed. This requires that the
DONE parameter is evaluated. This is the case when the value of the status parameter
DONE changes to 1.
8.2.8 FB/SFB 9 - URCV - Uncoordinated data reception
FB/SFB 9 URCV can be used to receive data asynchronously from a remote partner
FB/SFB of the type USEND (FB/SFB 8). You must ensure that parameter R_ID of both
FB/SFBs is identical. The block is ready to receive then there is a logical 1 at the EN_R
input. An active job can be cancelled with EN_R=0.
