 In order to work correctly, the CT_FB function block needs to be reset

each time before it is used.

 The number of available counters is limited and depends on the

settings in the system registers 5 and 6. The compiler assigns a NUM*

address to every counter instance. The addresses are assigned

counting downwards, starting at the highest possible address.

 The basic CT (see page 704) function (down counter) uses the same

NUM* address area (Num* input). In order to avoid errors (address

conflicts), the CT function and the CT_FB function block should not be

used together in a project.

In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

All input and output variables which are used for programming the function block CT_FB are

declared in the POU header. This also includes the function block (FB) itself. By declaring the FB

you create a copy of the original FB. This copy is saved under copy_name, and a separate data

area is reserved.
