Function Block
FC
→ Function
FORCE
Function which can be used to assign fixed values to specific tags in a user
program or CPU (also: I/Os), so that the user program is not able to change or
overwrite these values. The function allows users to set defined tag values in the
user program for use in specific situations and to test the programmable functions.
Function
According to IEC 61131-3, a function is a code block that does not contains any
static data. Temporary tags of functions are stored in the local data stack and will
be lost after the FC was executed.
Functions are therefore suitable for storing data in shared DBs. Because FCs are
not assigned a memory, you always need to specify their actual parameters. You
can not assign initial values to the local data of an FC.Grounding whose only purpose is to ensure the intended function of the electrical
equipment concerned. Functional grounding short-circuits any noise that might
otherwise have a detrimental effect on the equipment.
Function Block (FB)
According to IEC 61131-3, a function block (FB) is a code block that contains static
data. It is assigned an instance DB as memory. All parameters and static tags
passed to the FB are stored in the instance DB. Its temporary data are stored in the
local data stack.
Data in the instance DB are retentiveAn FB allows parameters to be passed in the
user program. Function blocks are therefore suitable for programming complex
functions, e.g. closed-loop controls, mode selections, which are repeated
frequently
Function Module (FM)
A programmable module which, in contrast to the CPU, has no multipoint interface
and can only be operated as a slave.
G
Global Data Communication
Global data communication is a procedure with which shared data are transferred
between CPUs.
Ground
The conductive mass of the ground whose potential can be assumed to be zero at
any point.
In the vicinity of ground electrodes, the ground may have a potential other than
zero. The term “reference ground” is often used in this situation.
Ground (verb)
To ground means connecting an electrically conductive part via a grounding system
to ground (one or more electrically conductive parts that have good contact with the
soil).
GSD File
The device master file (GSD file) contains all slave-specific data. The format of
GSD files is specified in EN 50170, Volume 2, PROFIBUS.Interrupt-triggering modules trigger a hardware interrupt in the case of a certain
