Global_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:
VAR_GLOBAL CONSTANT
stLibVersion_Tc3_Module : ST_LibVersion;
END_VAR
Name | Type | Description |
---|---|---|
stLibVersion_Tc3_Module | ST_LibVersion | Version information of the Tc3_Module library |
To check whether the version you have is the version you need, use the function F_CmpLibVersion (defined in the Tc2_System PLC library).
