PLC project
In any case, the PLC 802 Programming tool manages one project (logic
operations, symbols and comments). The download function is intended to
store all important information of a project in a control system.
The control system is able to store max. 4,000 instructions and 1,000 symbols.
The required PLC memory is influenced by the following components:
z
Number of instructions
z
Number and length of the symbol names
z
Number and length of the comments

A ladder diagram is a graphical programming language similar to electric circuit
diagrams.
ladder diagram
When creating a program using the ladder diagram form, then you will work
with graphical components to create the networks of your logics. To create your
program, you can use the following elements:
z
Contacts constitute a switch through which the current can flow. Current,
however, will only flow through a normally open contact if the contact is
closed (logical value 1). Current will flow through a normally closed
contact or a negated contact (NOT) if the contact is open (logical value
0).
z
Coils constitute a relay or an output which is updated by the signal flow.
z
Boxes constitute a function (e.g. a timer, counter or arithmetic operation)
which is carried out at the moment when the signal flow reaches the box.
A network consists of the elements mentioned above, forming a closed circuit.
The current flows from the left conductor bar (in the ladder diagram symbolized
by a vertical line at the left window) through the closed contacts, enabling coils
or boxes.
