Requirements
Development environment target platform PLC libraries to include
TwinCAT 3.1.4006 PC or CX (x86) Tc2_TempController
5.1.3 old:FB_TempController
The temperature controller block FB_TempController has a variety of inputs and outputs that are described
below. All the controller's parameters are passed to it via structures. The structures and enums are defined
here [}33].
