Parameters
Parameter Declaration Data Type Memory Area Description
EN_R INPUT BOOL I, Q, M, D, L Control parameter enabled to receive: when
EN_R = 1, FB 64 "TRCV" is ready to receive.
ID INPUT WORD M, D,
constant
Reference to the connection to be terminated.
ID must be identical to the associated
parameter ID in the local connection
description.
Range of values: W#16#0001 to W#16#0FFF
LEN INPUT INT I, Q, M, D, L
LEN = 0 (ad hoc mode): use implied
length specified in the ANY pointer for
DATA. The received data are made
available immediately when the block is
called. The amount of data received is
available in RCVD_LEN.
1 <= LEN <= max: number of bytes to be
received. The amount of data actually
received is available in RCVD_LEN. The
data are available after they have been
completely received. "max" depends on
the connection type: max = 1460 with
connection type B#16#01, max = 8192
with connection type B#16#11, max =
1452 with connection type B#16#12 with
a CP, max = 8192 with connection type
B#16#12 without a CP
NDR OUTPUT BOOL I, Q, M, D, L NDR status parameter:
NDR = 0: Job not yet started or still
running.
NDR = 1: Job successfully completed
ERROR OUTPUT BOOL I, Q, M, D, L ERROR status parameter:
ERROR=1: Error occurred during
processing. STATUS provides detailed
information on the type of error
BUSY OUTPUT BOOL I, Q, M, D, L
BUSY = 1: Job is not yet completed. A
new job cannot be triggered.
BUSY = 0: Job is completed.
STATUS OUTPUT WORD M, D STATUS status parameter: Error information
RCVD_LEN OUTPUT INT I, Q, M, D, L Amount of data actually received, in bytes
DATA IN_OUT ANY E, M, D Receiving area, contains address and length
The address refers to:
The process image input table
The process image output table
A bit memory
A data block
