CODESYS™ and PLCopen™ are the base for many PLC programming environments that share programming languages and development environment.However Object programming in these environments is oriented towards C++ object inheritance and other characteristics but limits access to the inside of program Blocks to IO variables. IEC DUTs (Data Unit Type) called UDT (User Defined Data Type) […]
hardware, SCADA vendor or IO list. Know How protection is a common response for source code requirements. There are not open standards that go beyond IEC 61131 PLC programming languages. Many things are kept open like: The software developer employs spreadsheets to witch you don’t have access. Software blocks are made with limitations like a […]
