10.3.2 FC 1 - RECEIVE_ASCII_STX_3964 - Receive from CP 240
This FC serves the data reception of the CP 240. Here you set 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 telegram is stored in ANZ. After the evaluation of the
telegram this bit has to be set back by the user, otherwise no further telegram may be
taken over by the CPU.
Parameter
Name Declaration Type Description
ADR IN INT Periphery address
_DB IN BLOCK_DB /
DB_ANY
_DB
n DB number of Type BLOCK_DB containing data
received, used in CPUs from VIPA or in S7-300
CPUs from Siemens.
n Pointer of Type DB_ANY to the DB containing
data received, used in S7-1500 CPUs from Sie-
mens.
ABD IN WORD Number of the 1. data word.
ANZ OUT /
IN_OUT
WORD ANZ
n Number of received bytes of Type WORD as
OUT parameter, used in CPUs from VIPA or in
S7-300 CPUs from Siemens.
n Number of received bytes of Type WORD as
IN_OUT parameter, used in S7-1500 CPUs from
Siemens.
PAFE OUT /
IN_OUT
BYTE PAFE (0 = OK)
n Parametrization error code of Type BYTE as
OUT parameter, used in CPUs from VIPA or in
S7-300 CPUs from Siemens.
n Parametrization error code of Type BYTE as
IN_OUT parameter, used in S7-1500 CPUs from
Siemens.
EMFR IN_OUT BOOL Acknowledgment of receipt
GEEM IN_OUT WORD Is internally used.
ANZ_INT IN_OUT WORD Is internally used.
EMPF_LAEUFT IN_OUT BOOL Status of the function.
LETZTER_BLOCK IN_OUT BOOL Is internally used.
FEHLER_EMPF IN_OUT BOOL Is internally used.
OFFSET IN_OUT WORD Is internally used.
Periphery address for calling the CP 240. You define the periphery address via the hard-
ware configuration.
n DB number of Type BLOCK_DB containing data received from the CP, used in CPUs
from VIPA or in S7-300 CPUs from Siemens.
n Pointer of Type DB_ANY to the data block, containing data received from the CP,
used in S7-1500 CPUs from Siemens.
