Function block diagram

A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines. An output of a block may also be connected to an input of another block:

Inputs and outputs of the blocks are wired together with connection lines, or links. Single lines may be used to connect two logical points of the diagram:

- An input variable and an input of a block

- An output of a block and an input of another block

- An output of a block and an output variable

The connection is oriented, meaning that the line carries associated data from the left end to the right end. The left and right ends of the connection line must be of the same type.

Multiple right connection, also called divergence can be used to broadcast information from its left end to each of its right ends. All ends of the connection must be of the same type.

Function block diagram is one of five languages for logic or control configuration supported by standard IEC 61131-3 for a control system such as a Programmable Logic Controller (PLC) or a Distributed Control System (DCS). The other supported languages are ladder logic, sequential function chart, structured text, and instruction list.

Plate block

A plate block, or plate-number block is a block of postage stamps that includes the part of the sheet margin with the serial number of the printing plate(s) used to print the stamps.

The numbering of printing plates has long been a part of quality control in the printing process. In some cases, for instance the Penny Reds of Great Britain and modern United States plate number coils, the plate numbers appear in the stamps themselves, but the more common practice is to include the number in the margin of each sheet, frequently alongside the name of the printer.

Stamps printed in several colors will have several plate numbers in the sheet margin, one for each color. Stamps printed in large quantities may have multiple plate numbers.

The usual practice in plate block collecting varies by country and era; the classic 20th century United States plate block consists of a 2×2 block in the corner of the sheet. The ambitious collectors will seek to own blocks displaying every known plate number for the stamp; specialized stamp catalogs will list these.
