Outline
Itself with the power of the PLC languages (ladder language) embedded into the microcontroller, microcontroller product development to make use of assembly language from a ladder into the use of language, while access to the ladder diagram programming platform provides a variety of powerful applications , so called embedded PLC. PLC can be widely used in embedded Microcontroller products, and can not replace all the microcontroller functions in the field can change the product.
 Embedded PLC products have the following characteristics:
Written application with the ladder.
Connection with a number of man-machine interface, such as Delta, EView so.
Changing the application functionality is very easy, unlike the single chip products, to change the hardware and software so cumbersome.
Parallel operation with other manufacturers PLC.
485 can be formed.
To set the encryption password.
