8.7.3.2 RECEIVE Command
Description: This command enables data to be received without restric-
tion via the interface and written to the indicated buffer.
Parameter word Contents
PW4 Command identifier - RX (Receive)
Parameter word Contents
PW5 Monitoring time in 10 ms matrix
Maximum selectable time (10 ms * 65535) is approximately 10 min. When
0 (zero) is specified, the time monitor is switched OFF. The monitoring ti-
me indicates the maximum time between two characters.
NOTE –
The sequence of the monitoring time in the DW4 denotes the normal end
of the receive process and not a termination with fault.
If a data copy is attached, fault 0305H is issued in the status word and
4003H in the fault word, provided a character has not already been recei-
ved. (Receive buffer empty)
Parameter word Contents
PW6 PLC Receive buffer size (10-256 bytes)
This parameter specifies the size of the Receive buffer on the R500 mo-
dule and on the PLC side.
Parameter word Contents
PW7 Receive-data length (max. 256 bytes)
This parameter can specify, e.g., the length of the data during the Recei-
ve process. BÜP03E normally concludes the Receive process when the
specified number of characters has been reached. At the same time all
received characters (including control characters) are counted. When the
length is 0 (zero), the stringsize condition is ignored.
PW8 - PW16 are reserved.
