6.5 Parameter Fields for Connection Types
General
Below, you will see which values need to be entered in the parameter fields and
which subfields are used for the various connection types.
Some applications do not require all the subfield types - refer once again to the
table for details.
Note
Please read the explanations of the configurable connection properties for the
individual connection type in Chapter 5!
Connection ID
The ID parameter that precedes each connection parameter field beside the type
ID is particularly important.
On programmed connections, you can assign this ID freely within the permitted
range of values. You must then use this ID on the call interface of the FCs for the
SEND/RECV interface to identify the connection.
Range of values for the connection ID:
 S7-400: 1,2 through 64
 S7-300: 1,2 through 16
