Heĺlo Omkris; Add-on Instructions are a feature of Rockwell PLC programming, used for example to integrate specific equipment or repetitive functions in the RSLigix program: https://m.youtube.com/watch?v=S5KBwyZubSw I could understand if you were asking to create some similar code in MicroWin, such as a subroutine, but that is not what you are asking... Please describe the application you need help with. Hope this helps, |

Hello DChartier, My application is Positioner controlling with four types of Operational Phiilosophy: FAST/SLOW along with UP/DOWN controls and the output will be only Analog Output 4-20mA signal. We have 05 numbers of Positioner having similar control philosophy but problem is that I haven't worked in S7 200 CN self program building ability. That's why I am seeking your help! Regards OmKris |

Hello Omkris; First, a S7-200CN is a S7-200 (European model) that has been adapted to the chinese market. Programming is the same, but the setup language must ne Chinese if you want to write code. S7-200 https://support.industry.siemens.com/tf//ww/en/posts/s7-200/113814/?page=0&pageSize=10 Next, to understand the basis of subroutines in the S7-200, the best source is the Tips and Tricks programs, showing code and structure for various types of process control based on a S7-200. What are S7-200 programming tips and where can you procure them? https://support.industry.siemens.com/cs/ww/en/view/1232912 There is a section on Positioning, i do not remember if there are specific tips on positioners, but please download and open the many examples you will find in that link. At the very least they will show you how you can build and parameterize a subroutine (to call it for different positioners, for example), which you will need to develop your own application. The best source of information on the S7-200 will always be the S7-200 System Manual. Look up the sections onsubroutines and pointers in this link: https://support.industry.siemens.com/cs/us/en/view/1109582 Hope this helps, Daniel Chartier |
