PLC API

This chapter describes the PLC API of the TwinCAT 3 TestFramework. There are two PLC libraries available for this purpose that can be used in conjunction with the TF1140. The Tc3_PlcTestFramework PLC library and the Tc3_PlcTestUtilitiesGeneric. You are required to include the first one. Among other things, it contains the base class for the test cases (FB_TestCaseBase).

The Tc3_PlcTestUtilitiesGeneric PLC library contains additional function blocks with convenience functions that would otherwise have to be programmed into the PLC application (access to the parameters of a TwinCAT 3 runtime module, a list of ADS error codes, etc.).
