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_DataExchange : ST_LibVersion;
END_VAR
stLibVersion_Tc2_DataExchange: Version information of Tc2_DataExchange (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All other options for comparing library versions, which you may know from TwinCAT 2, are outdated! |
