As one of the five programming languages defined by the IEC 61131-3 standard, our HMI+PLC (HMC) and PLC (MLC) configuration software MAPware-7000 supports the Structured Text (ST) editor.
The Structured Text editor is a text-based editor similar to text-based programming languages such as C/C++ or Visual Basic. Logical operations are created by combining variable names with operators to create logical statements.
The PLC executes the statements from top to bottom as the program is executed. The Structured Text editor provides a great deal of flexibility to the programmer.
