Placeholder represents a program name: Program.bToggle Major.bToggle Chemical The converter cannot transfer this form of placeholder to TwinCAT 3.1. However, they are usually rarely utilized in practice.You should become aware of the limitations described below the using guide.
To search, you can arranged the document filtration system in the bottom level right-hand part of the dialog. After that thé TwinCAT 2.x converter begins automatically. The TwinCAT 2.x converter bank checks whether the project can become compiled without error. If the task contains visualization items with placeholder variables that the converter cannot take care of, the particular visualizations are integrated straight as a grouping in location of the creation references. Library transformation: If a library for which no transformation rule offers been defined yet can be referenced in the project to be opened up, the dialog Switching a library research appears. Define here whether and how the converter should change the previous library guide by an up-to-date one. If in performing therefore you choose a library for which the project information can be missing, the Project information discussion appears, which you have got to fill out. Twincat 3 Code Positions IfPlease be aware that the converter just adapts the format at these program code positions if the TC2 task to be transformed can end up being put together on the TC2 part. Particularly, this means: During the conversion procedure, the converter included in TC3 very first compiles the selected TC2 task with a TC2 compiler. Syntax changes of the TC2 code are just made during the development of the TC3 SPS task if this TC2-side compilation will be successful. The prerequisite for a productive TC2-part compilation is definitely that all required TC2 your local library are made available to the converter. This can be achieved, for example, by inserting the your local library referenced in the TC2 project into the foIder C:TwinCAT3.1ComponentsPlcConverterLib, or by informing the converter of the areas of the TC2 your local library via the displayed transformation dialogs. Collection It must be feasible to put together the project in TwinCAT 2.x PLC Handle without compilation errors. Nonetheless, TwinCAT problems alerts during the compilation. These are evoked by implicit conversions that can lead to the loss of information (for example owing to the modification of a indication). TwinCAT 3.1 testing case statements against the change variable: CASE USINT OF INT can be not examined in TwinCAT 2.x, but an mistake message is definitely shown when adding into TwinCAT 3.1. Your local library All variables and constants utilized in a library also possess to be announced in this library. It must become feasible to compile the library in TwinCAT 2.x without mistakes. A local declaration of an enumeration is usually no more time feasible, except within TYPE: in the situation of a TwinCAT 2.x import a nearby enumeration assertion is automatically transformed into an specific type definition. INI can be no more supported (you have to replace this in the code by the Init method). In function calls, it can be no much longer probable to combine precise parameter projects with implicit tasks. As a result the purchase of the parameter insight tasks can become changed: fun(formal1: real1, actual2); Fehlermeldung enjoyment(formal2: actual2, official1: real1); gleiche Semantik wie folgende Zeile: fun(official1: actual1, official2: actual2); TwinCAT 2.x pragmas are usually not converted. They create a warning in TwinCAT 3.1. Storage In contrast to TwinCAT 2, TwinCAT 3.1 has an 8-byte position. For further information and examples see Reference point Programming Positioning. Situations of the information type Thread are usually pre-initiaIized in TwinCAT 2 by zeroing the entire memory area. In TwinCAT 3.1, nevertheless, just the very first byte of like an example can be zeroed. Placeholder talks about a program title: Program.bToggle Primary.bToggle Deb The converter cannot move this type of placeholder to TwinCAT 3.1. However, they are rarely utilized in exercise.
