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

The tables describe how the different pins of the function block are used in Free-large mode.

The table describes the input variables:

Input	Type	Description
EN_Enable	BOOL	Not used
EN_Sync	BOOL	When SYNC input is configured: if TRUE, authorizes the counter synchronization and start via the Sync input.
EN_Cap	BOOL	When CAP input is configured: if TRUE, enables the Capture input.
EN_Compare	BOOL	TRUE = enables the comparator operation (using Thresholds 0, 1): obasic comparison (TH0, TH1 output bits) oreflex (Reflex0, Reflex1 output bits) oevents (to trigger external tasks on threshold crossing)
EN_Out0	BOOL	TRUE = enables physical output Output0 to echo the Reflex0 value (if configured).
EN_Out1	BOOL	TRUE = enables physical output Output1 to echo the Reflex1 value (if configured).
F_Enable	BOOL	Forces the Enable condition.
F_Sync	BOOL	Forces the Sync condition
F_Out0	BOOL	TRUE = forces Output0 to TRUE (if Reflex0 is configured).
F_Out1	BOOL	TRUE = forces Output1 to TRUE (if Reflex1 is configured).
ACK_Modulo	BOOL	On rising edge, resets Modulo_Flag.
ACK_Sync	BOOL	On rising edge, resets Sync_Flag.
ACK_Cap	BOOL	On rising edge, resets Cap_Flag.
SuspendCompare	BOOL	TRUE = compare results are suspended: oTH0, TH1, Reflex0, Reflex1, Out0, Out1 output bits of the block maintain their last value. oPhysical outputs FQ0 and FQ1 maintain their last value oEvents are masked NOTE: EN_Compare, EN_Out0, EN_Out1, F_Out0, F_Out1 remain operational while SuspendCompare is set.

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. Use the HSCGetDiag function block 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	[Counting Up] TRUE when CurrentValue ≥ Threshold 0. [Counting Down] FALSE when CurrentValue ≤ Threshold 0.
TH1	BOOL	[Counting Up] TRUE when CurrentValue ≥ Threshold 1. [Counting Down] FALSE when CurrentValue ≤ Threshold 1.
Modulo_Flag	BOOL	Set to TRUE when the counter rollovers its limits
Sync_Flag	BOOL	Set to TRUE by the synchronization of the counter
Cap_Flag	BOOL	Set to TRUE when a new capture value is stored in the Capture register. This flag must be reset before a new capture can occur.
Reflex0	BOOL	State of Reflex0.
Reflex1	BOOL	State of Reflex1.
Out0	BOOL	State of physical outputs Output0 (if Reflex0 configured).
Out1	BOOL	State of physical outputs Output1 (if Reflex1 configured).
