HONGKE Automation softPLC is a programming environment for developing PLCs for real-time operating systems such as Linux, Xenomai, INtime, Windows, etc. It is very suitable for users who need to use IEC61131-3 and PLCopen standard control technology and PLC programming.<\/strong>This article will help you create and develop functions and function blocks using the IEC language.<\/p>\n\n\n\n

Hongke Automation softPLC Studio Naming Rules<\/strong><\/p>\n\n\n\n

# Functions written in IEC language are called subroutines.<\/p>\n\n\n\n

# Function blocks developed in the IEC language are called UDFBs.<\/p>\n\n\n\n

# UDFB stands for \u201cUser Defined Function Block\u201d.\u201d<\/p>\n\n\n\n

Note: This document is for Automation softPLC Studio version 1.0 or higher. automation softPLC Studio needs to be installed on a Windows PC.<\/p>\n\n\n\n

Step 1: Creating and using subroutines<\/h2>\n\n\n\n

Click Insert New Program from the workspace menu.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

After naming it, select the language you want, note that this language cannot be SFC.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Clicking OK opens another dialog box that lets you define the outputs and outputs of the subroutine.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n


Use the workspace menu to modify parameters.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

In the Local Variable Editor, you can still see these parameters and can add or modify them<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After completing the above settings, the subroutine can be called from other POUs.<\/p>\n\n\n\n

\n\n\n\n

Step 2,Creating and Using a UDFB<\/strong><\/h2>\n\n\n\n

The above steps also apply to User Defined Function Blocks (UDFB), note that you need to select the \u201cUDFB\u201d option in the New Program dialog box.<\/p>\n\n\n\n
