There is shown below which values are needed to be entered in the parameter fields and
which subfields are to be used for the various connection types. Some applications do not
require all the subfield types. The ID parameter that precedes each connection parameter
field beside the type ID is particularly important. On programmed connections this ID may
freely be assigned within the permitted range of values. For identification of the connec-
tion this ID is to be used on the call interface of the FCs for the SEND/RECV.
Range of values for the connection ID: 1, 2 ... 64
