TB711FC1 is a PLC module, specifically a module from Siemens. Siemens PLC programming languages are SCL and STL, of which SCL is a text language similar to Pascal language, with the advantages of easy to read, easy to diagnose and maintain. STL, on the other hand, is a powerful language, but programming requires extreme care because its register addressing features are similar to address Pointers in some computer high-level languages.
For PLC programming, should pay more attention to the architecture of the program and improve the standardization of program production efficiency, a good PLC program should not only understand themselves, but let more people understand. In general, it should be given a scan cycle of more than 0.05s or more than two.
In addition, for the position control instructions in PLC programming, at each return to the origin or start the moment, the current position is cleared to zero. When the position control is back to the origin, it must be used to return to the origin command, and the data can not be taken.
