Ladder program was like the following,I dont spend more time to do more desicriptionsīefore complaining about that it was so ugly, I need to talk about my dream.

IO_SIMULATOR is just only an interface for control input and see output status via file,name input.txt and output.txt each byte indicate X000 to X007 and Y000 to Y007. PLC program just implement a multimedia timer to computation timer object and parsing,computation working thread to computation ladder program to control output to proper status. I hope I can provide all of design document including Flow diagram,status diagram but it will take many time.

I know its just simulator, but after improvI/O control module it can be real PLC for daily life. You can enjoy editing ladder program to test PLC program in ordering to check whether it is enough or any suggest. the PLC program running, click Sel Ladder file to load ladder programĤ.You can stop at any time as you want by click Stopĥ.After PLC is running, you can use IO_SIMULATOR.exe to simulate input and watching output.Ħ.click X000 and X001 to switch on input X000,X001 then ouput Y000 will switch on by PLC.ħ.click X006 to switch on input X006 after 5 sec output Y002 will switch on by PLC.Ĩ.click X002 to switch on input X002 in order to switch off output Y000(in our ladder program Y000 with Counter were mutually exclusive) then click X005 on/off for 5 times then output Y002 will be switch on by PLC I have wroten a program IO_SIMULATOR.exe to simulator input and output via file input.txt and output.txt the example ladder program also included in files for downloadingġ. In the simulator environment, we dont need I/O control card. It is parsing ladder program, reading input and doing computation then doing output. PLC.exe is a Programmable Logic Controller simulator program. PLC was controlled by input and ladder program after program computation PLC will control output, after all you can control electronic devices as you want. The PLC programming language is knowen like ladder diagram symbol, Person who is familiar with electronic automatic control, should be familiar with it. In order to control peripheral electronic devices such as RelayMagnetic-contactorssolenoid valveetc. Programmable Logic Controller was designed for most industrial application. Ill keep it as real as possible, if I have plenty of time. I dreamed about it for almost 15 years and now my dream come true. Here is my first version of PC PLC SIMULATOR program.
