n The DONE output shows "order ready without error". If there was an ERROR, the cor-
responding event number is displayed in the STATUS. If no error occurs the value of
STATUS is "0".
n DONE, ERROR and STATUS are also output in response to a reset of the FB. In the
event of an error, the binary result BR is reset. If the block is terminated without
errors, the binary result has the status "1".
n Please regard the parameter DONE, ERROR and STATUS are only available at one
block call. For further evaluation these should be copied to a free data area.
10.2.3 FB 61 - RECEIVE - Receive from System SLIO CP 040
This FB serves for the data reception from the System SLIO CP 040. Here you set the
reception range via the identifiers DB_NO and DBB_NO. The length of the telegram is
stored in LEN.
Parameters
Parameter Declaration Data type Description
EN_R IN BOOL Release RECEIVE data.
R IN BOOL Release synchronous reset.
LADDR /
HW_ID
IN INT /
HW_IO
n LADDR
– Logical base address of the CP.
– When used in CPUs from VIPA or S7-300 CPUs from Sie-
mens.
n HW_ID
– HW identifier to address the CP.
– When used in S7-1500 CPUs from Siemens.
DB_NO IN INT Number of DB containing received data.
DBB_NO IN INT Data byte number - receive data starting from data byte.
IO_SIZE IN WORD Configured IO size of the module.
LEN OUT INT Length of received telegram in byte
NDR* OUT BOOL Receive order finished without errors.
ERROR* OUT BOOL Receive order finished with errors. Parameter STATUS contains the
error information.
STATUS* OUT WORD Specification of the error with ERROR = 1.
CONTROL IN_OUT BYTE Divided byte with RECEIVE handling block:
SEND (bit 0 … 3), RECEIVE (bit 4 … 7).
*) Parameter is available until the FB is called.
Enable Receive - Release to read:
n With signal status "1" at EN_R the examination, whether data from the CP are read,
is released. Depending upon the number of data, a data transfer can run over several
program cycles.
n At any time a current order may be cancelled with signal state "0" of EN_R. Here the
cancelled receipt order is finished with an error message (STATUS).
n The Receive function is deactivated as long as EN_R is statically set to "0".
