Parameter Declaration Data type Description
DATAPTR IN ANY Pointer to Data Buffer for sending data
DATALEN OUT WORD Length of data sent
RETVAL OUT WORD Return value (0 = OK)
Here you define a range of the type Pointer for the send buffer where
the data to be sent are stored. You have to set type, start and length.
Example:
Data is stored in DB5 starting at 0.0 with a length of 124byte.
DataPtr:=P#DB5.DBX0.0 BYTE 124
Word where the number of the sent Bytes is stored.
At ASCII
if data were sent by means of FC/SFC 217 faster to the
serial interface than the interface sends, the length of data to send
could differ from the DATALEN due to a buffer overflow. This should
be considered by the user program.
With STX/ETX, 3964R, Modbus and USS always the length set in
DATAPTR is stored or 0.
Return values of the block:
Error code Description
0000h Send data - ready
1000h Nothing sent (data length 0)
20xxh Protocol executed error free with xx bit pattern for
diagnosis
7001h Data is stored in internal buffer - active (busy)
7002h Transfer - active
80xxh Protocol executed with errors with xx bit pattern for
diagnosis (no acknowledgement by partner)
90xxh Protocol not executed with xx bit pattern for diagnosis
(no acknowledgement by partner)
8x24h Error in FC/SFC parameter x, where x:
1: Error in DATAPTR
2: Error in DATALEN
8122h Error in parameter DATAPTR (e.g. DB too short)
807Fh Internal error
809Ah interface not found e.g. interface is used by PRO-
FIBUS
809Bh interface not configured
