Main type is always managed by an HSCMain function block.
NOTE: At build, an error is detected if the HSCMain function block is used to manage a different HSC type.
Adding a HSCMain Function Block
|
Step |
Description |
|---|---|
|
1 |
Drag the Libraries > Controller > HMISCU > HMISCU_HSC > HSCMain FB to the Application tree > HMISCUxx5 > POU and drop it on the Start Here box in the lower window. |
|
2 |
The instance name is located in the Variable field at the Device tree > HMISCU••5 > Embedded Functions > HSC > HSC0• with the HSC0• > Type that is set to Main. Using the input assistant, the HSC instance can be selected at the following path: Embedded Functions > HSC |
|
NOTE: This method is for ST, LD, or FBD languages. |
