Fig. 9.1. Example functor

Some functors are equipped with one or more variable parameter(s) to modify computation

in the functional block. These parameters given as

settings

are accessible in the utility software

–

Monitor3

; the values can be changed as the application is evaluated.

While developing the application, the developer determines some features of settings (e.g.
precision of counting time delays), assigns names to chosen settings (if other names than
default ones are required), assigns settings to one of the defined

setting groups

, assigns names

to chosen setting values and decides on conditions of access to the setting.

Each functor output is assigned with an initial

DNP-3.0 protocol index

. The output index

with  the  number  0  can  be  arbitrarily  (but  not  in  contradiction  to  other  indices)  defined  and
modified  at  the  stage  of  application  description.  Indices  of  subsequent  functor  outputs  are
consecutive values of the output index 0. The  functor in the figure takes two indices with the
number n for the output 0 and the number n+1 for the output 1.

For each functor output (and thus, for each DNP-3.0 index), capability for generating a

report

about each or a specified change in the logic state can be assigned. The report can be

described with a text as desired. Selected reports can be assigned to

class 1

in DNP-3.0 or

independently classified for presentation on the

Monitor3

screen or be included to a set of

events presented in the window of

bay fault indication

Output activation can also result in generation of

a text

presented on the device display and

the

Monitor3

screen. The text information is determined in the course of application

development. The text can have up to 32 characters.

Functors are inserted into the program sheet by loading them from the collection set

available in the

LogCZIP

editor. Functors representing virtual resources (like logic gates,

analogue  inputs,  etc.)  can  be  inserted  into  sheets  in  any  number,  whereas  other  elements
associated with physical resources (like inputs from terminals, relays, etc.) can be inserted until
their number is the collection set is used up.
Once  necessary  functors  are  arranged  in  the  sheet,  they  must  be  related  to

lines

labeled

lines

. The line drawing mode is activated by the pencil icon /

Edycja → Rysuj

/. Labels are

equivalent to the line to which they are attached. (These are an abstract extension of the line to
be able to transfer links to other project sheets.). The label also assigns the relation name. Lines
without labels are unnamed.

The relation must meet correctness conditions. Some of them are verified on an ongoing

basis in the graphic editor, whereas other conditions, during project compilation. Improper or
impossible relations must be corrected until correctness is confirmed. This process may require
selection of other functors or addition of intermediate functors to improve connecting
capability.
