What is Ladder Logic Programming?
The programming language of the T1 is ‘ladder diagram’.
Ladder diagram is a language which composes program using relay symbols as a base in an image similar to a hard-wired relay sequence. In the T1, 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 connected each other.
