Library version
All libraries have a certain version. The version is indicated in the PLC library repository, for example. A global constant contains the information about the library version:
Global_Version
VAR_GLOBAL CONSTANT
stLibVersion_Tc2_SUPS : ST_LibVersion;
END_VAR
Name | Type | Description |
|---|---|---|
stLibVersion_Tc2_SUPS | ST_LibVersion | Version information of the Tc2_SUPS library (type: ST_LibVersion) |
 | To check whether the version you have is the version you need, use the function F_CmpLibVersion (defined in the Tc2_System library). All other options for comparing library versions, which you may know from TwinCAT 2, are outdated. |
