General PLC Management General PLC Management application is designed and developed by Patrick Li who owns the intellectual property. Currently only Simens S7 PLCs are validated that they works great, although the code supports Omron FINS PLCs based on serial port (COM port), but not fully tested yet. This application underlyingly takes multiple layers to best provide the simple operation methods to users. 1. the low level COM component just handle PLC info and variables in SQLite 3 database (Used the 1st NuGET package GeneralSQLiteViewer) 2. only 1 item is placed in config file and all others are configured into the database file referenced by this item, the General Config v2 tool to handle all the items in database 3. UserMgr v2 COM component (The 2nd NuGET package UserMgr_v2) handles all users and permissions related transaction 4. If you set a correct SDK vendor name, then the application will find the corresponding PLC DLL, so it is very simple to communicate and control PLCs The only prerequisite: You must run GeneralInstaller (the 3rd NuGET package) to install some necessary components with Administrator permission. Just run GeneralInstall.exe and all the COM components will be registered. It takes advantage of CSVMultilang (The 4th NuGET package) to implement multilang. You are suggested to refer to the DOCX or PDF document (equivalent) under the sub folder 'docs', which also encloses sample code to call the SDK to control PLCs. Sample database files are under the sub folder 'assets'. Installing bits are zipped and placed under sub folder 'install', please unzip it and run GeneralInstaller.exe with Administrator permission, so you can use this application which is really a good product.
