FIFO Ring buffer max. 250 telegrams 1024byte
CONTROL Software handshake via CONTROL block
For recognizing a signal change a minimum pulse time is necessary. The
decisive factors are CPU cycle time, the refresh time on the CP and the
response time of the communication partner.
10.2.2 FB 60 - SEND - Send to System SLIO CP 040
This FB serves for the data output from the CPU to the System SLIO CP 040. Here you
define the send range via the identifiers DB_NO, DBB_NO and LEN. A rising edge at
REQ a transmission is initiated and the data is sent.
Parameters
Name Declaration Type Description
REQ IN BOOL Release SEND with positive edge.
R IN BOOL Release synchronous reset.
