10.3.5 FC 11 - ASCII_FRAGMENT - Receive fragmented from CP 240
Please note that this block can only be used in CPUs from VIPA or in
S7-300 CPUs from Siemens!
This FC serves the fragmented ASCII data reception. This allows you to handle on large
telegrams in 12byte blocks to the CPU directly after the reception. Here the CP does not
wait until the complete telegram has been received. The usage of the FC 11 presumes
that you’ve parameterized "ASCII-fragmented" at the receiver. In the FC 11, you define
the reception range via the identifiers _DB and ABD. When the output EMFR is set, a
new telegram has been read completely. The length of the read telegram is stored in
ANZ. After the evaluation of the telegram this bit has to be set back by the user, other-
wise no further telegram may be taken over by the CPU.
Parameters
Name Declaration Type Comment
ADR IN INT Logical Address
_DB IN BLOCK_DB DB number of DB containing data received.
ABD IN WORD No. of 1st data word received
ANZ OUT WORD No of bytes received
EMFR IN_OUT BOOL Receipt confirmation
GEEM IN_OUT WORD Internal use
ANZ_INT IN_OUT WORD Internal use
EMPF_LAEUFT IN_OUT BOOL Internal use
LETZTER_BLOCK IN_OUT BOOL Internal use
FEHLER_EMPF IN_OUT BOOL Internal use
PAFE OUT BYTE Parameterization error (0 = OK)
Periphery address with which you may call the CP 240. Via the hardware configuration
you may set the periphery address.
Number of the data block, which contains the data to be received.
Word variable that contains the number of the data word from where on the received
characters are stored.
Word variable that contains the amount of bytes that have been received.
By setting of EMFR, the handling block announces that data has been received. Only by
setting back EMFR in the user application new data can be received.
