Permitted values, remark
Cancels the request in progress. Receiving is
disabled. Default: 0
The start address is taken from STEP 7.
Receive DB no.: CPU-specific, zero is not allowed
(Relevant only for DX data destination)
0 ≤ DBB_NO ≤ 8190 Receive data starting from
data byte
(Relevant only for DX data destination)
'D': Data block
0 ≤ L_NO ≤ 255
0 ≤ L_OFFSET ≤ 510
0 ≤ L_CF_BYTE ≤ 255255 means: without
interprocessor communication flag
0 ≤ L_CF_BIT ≤ 7
STATUS parameter == 16#00;
Error information is written to the STATUS
parameter.
0 ≤ LEN ≤ 4096, specified in number of bytes
If ERROR == 1, the STATUS parameter will
contain error information.
