Programming languages
The following programming languages can be used in each program block.
Graphic languages
1. Structured ladder language
This graphic language is created based on the relay circuit design technology.
Any circuit always starts from the bus line located on the leftmost.
The structured ladder language consists of contacts, coils, functions and function blocks. These components
are connected with vertical lines and horizontal lines.

Text language
1. ST (Structured text) language
The ST language can describe control achieved by syntax using selective branches with conditional
statements and repetition by repetitive statements in the same way as high-level languages such as C
language.
By using the ST language, you can create simple programs easy to understand.
