• If you have configured, using virtual connections, more data than
specified at connection LTT of function block @PEER, then this
excess data is
cut-off.
•
If you have configured, using virtual connections, less data , than are
specified at the LTT connection of function block @PEER, then the
telegram is
filled-up with "0s".
•
The transmit telegram is started synchronously to the sampling time of
the CTV function block, i.e. there is no dead time.
Please refer to the "Manual, configuring the communications D7-SYS,
Chapter communications utility, process data" for additional configuring
rules for exchanging process data.

•
If you have configured, using virtual connections, less data , than are
specified at the LTR connection of function block @PEER, then the
telegram is
filled-up with "0s".
•
The transmit telegram is started asynchronously to the sampling time
of the CRV function block after a telegram has been received, i.e. the
sampling time of function block CRV is the max. deadtime between
receiving and processing data.
Please refer to the "Manual, configuring the communications D7-SYS,
Chapter communications utility, process data" for additional configuring
