Fig. 3-107 Configuring: Receiving and transmitting with virtual connections
Configuring rules with reference to the example:
• The virtual connections, which belong to a virtual connection name,
can be configured at block I/O with different data types (ANY_FB.Y1
"REAL" and ANY_FB.Y6 "INTEGER") and in any sequence.
• Virtual connections (receive) at block inputs can be configured a
multiple number of times if the inputs have the same data type. These
inputs are supplied with identical data. (ANY_FB.X4 and X5)
• The same virtual connection (transmit) with identical connection name
and sequence number may not be configured a multiple number of
times at block outputs.
• Several different virtual connections (transmit) can be configured at a
block output (ANY_FB.Y3). The connections can differ, both in the
connection name as well as in the sequence number.
