7.6 Programming Language
The programming language of theV200 Series is ‘ladder diagram’. Ladder diagram is a language which composes
pro- gram using relay symbols as a base in an image similar to a hard-wired relay sequence. In the V200 CPU, in
order to achieve an efficient data-processing program, ladder diagram which are combinations of relay symbols and
function blocks are used.
The ladder diagram program is constructed by units called ‘rung’. A rung is defined as one network which is con-
nected to each other.
Rung number
1

Rung
The rung numbers are a series of numbers (decimal number) starting from 1, and cannot be skipped. There is no
limit to the number of rungs.
The size of any one rung is limited to 50 lines X 11 columns.
A example of a ladder diagram program is shown below.
When X005 is ON or the data of D0100 is greater than 200, Y027 comes ON. Y027 stays ON even if X005 is OFF
and the data of D0100 is 200 or less.
Y027 will come OFF when X006 comes ON.
