This Part of BS 1646 specifies symbols for the representation of process computer and shared\/control functions in the field of process measurement and control.<\/p>\n

The symbols established in this part have been developed to be used in conjunction with the symbols devised in BS 1646-1 and BS 1646-2 and are supplementary.<\/p>\n

They are intended to provide a means to illustrate process computer and\/or shared display\/control functions in the field of process measurement and control and may be used separately or combined with the symbols of BS 1646-1 and BS 1646-2. They will enable users to show and identify in a simple form the functions of instruments, the process computer and shared display\/control functions or any combination of these.<\/p>\n

It is permissible to use the basic symbol for computer based functions (see 3.1<\/b>) throughout for any software based digital system. This is not intended to preclude the use of the basic symbol for shared display\/control functions (see 3.2<\/b>) if the user considers this to be appropriate.<\/p>\n

The symbols are intentionally limited to the identification on process flow diagrams, etc and do not provide a means of illustrating specific instruments or parts thereof.<\/p>\n

The letter code for function identification is given in the Tables of BS 1646-1 and BS 1646-2.<\/p>\n

The application methods are shown in the examples.<\/p>\n
