Programming the Main Type

Overview

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 the 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.

Description

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.

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

I/O Variables Usage

These table describes how the different pins of the function block are used in the mode Event.

The table describes the input variables:

Input	Type	Description
EN_Enable	BOOL	Not used
EN_Sync	BOOL	When SYNC input is configured: if TRUE, allows the setting of the counter value to 0.
EN_Cap	BOOL	Not used
EN_Compare	BOOL	Not used
EN_Out0	BOOL	Not used
EN_Out1	BOOL	Not used
F_Enable	BOOL	Forces the Enable condition.
F_Sync	BOOL	Forces the Sync condition
F_Out0	BOOL	Not used
F_Out1	BOOL	Not used
ACK_Modulo	BOOL	Not used
ACK_Sync	BOOL	On rising edge, resets Sync_Flag.
ACK_Cap	BOOL	Not used
SuspendCompare	BOOL	Not used

The table describes the output variables:

Outputs	Type	Comment
HSC_REF	HSC_REF	Reference to the HSC. To be used with the HSC_REF_IN input pin of the function blocks.
Validity	BOOL	TRUE = indicates that output values on the function block are valid.
Error	BOOL	TRUE = indicates that an error was detected. HSCGetDiag function block may be used to get more information about this detected error.
CurrentValue	DINT	Current count value of the counter.
Run	BOOL	TRUE = Counter is running.
TH0	BOOL	Not used
TH1	BOOL	Not used
Modulo_Flag	BOOL	Not used
Sync_Flag	BOOL	Set to TRUE by the synchronization of the counter
Cap_Flag	BOOL	Not used
Reflex0	BOOL	Not used
Reflex1	BOOL	Not used
Out0	BOOL	Not used
Out1	BOOL	Not used
