ST语言是一种专门用于PLC编程的语言，被广泛应用于工业自动化领域。今天，我们就来探索一下ST语言的魅力！

《使用入门！ST 语言》适用于以下情况

● 对复杂的条件分支和运算程序感到困扰

● 希望编写高沿用性程序

● 曾经使用 C 语言等编程语言进行过开发但不熟悉梯形图程序

的 ST 语言准备了超过 200 种函数，让您以使用编程语言的感觉轻松控制 PLC。

我们严格挑选了常用的 86 种函数，并结合实际现场的使用示例进行简洁明了的解说。

用好 ST 语言，可以轻松记述复杂的条件分支和运算处理，因此能够大幅减少程序编写工时。此外，该语言是符合国际标准的编程语言，因此可越过厂商之间的壁垒，沿用所需的程序。

让我们一起揭秘ST语言的魅力，探索工业编程的新世界，为工业自动化注入更多的智慧和创新！
