2.5 Data point typicals
Introduction
Data point typicals consist of one or more data points of the same type, e.g. 4 bytes of binary
information, or 4 analog values, or 1 byte commands, etc.
Data point typicals for a specific type or amount of information always come in two versions:
● A typical for acquiring and sending
For example, FB Bin04B_S, for acquiring and sending 4 bytes of binary information
(status signals);
● A typical for receiving and outputting
For example, FB Bin04B_R, for receiving and outputting 4 bytes of binary information
(status signals).
All data point typicals are FBs. An instance DB must be specified when an FB is called. The
number of this instance DB is identical to the object number of the data point object. At the
send and receive ends this object number does not have to be identical.
Structure of typical names
Data point typicals have 8-character names based on the following scheme:
