A maintained IEC61131 to C transpiler

A simple function block to make it easier and clearer to program a state machine in structured text (IEC 61131-3). If you write your state machine with a CASE instruction and an enum, you might miss functions like an entry and exit step, timeout functions or logging possibilities. This module should show you how you can implement all these things. The example was created with TwinCAT and uses the TwinCAT Eventlogger. The basic concept is also possible in Codesys.

UniTest is a PLC, IDE and manufacturer agnostic library written using only the features of the IEC61131 standard. Due to this, portability to all IEC compliant platforms is straightforward and can be achieved programmatically or with minimal manual work.

A library that provides tools for working with dynamic strings in TwinCAT. It includes a comprehensive string builder with string enumeration and a read-only string builder adapter. Additionally, there are several C-style string functions, such as strstr(...), strlcpy(...), isspace(...), and more.

In TwinCAT there are some functions available for debugging. The best known is probably the breakpoint. But this is used with caution, because it stops a running machine immediately. Therefore it is often avoided by programmers by using counters or flags to check the sequence of a control. In addition to the breakpoint, there is also the execution point, which does not stop the machine. I suspect that many are not aware of this feature and so I would like to share it briefly.
