Programming the Main Type

Overview

The Main type is always managed by an HSCMain function block.

NOTE: At build time, a detected error code is given if the HSCMain function block is used to manage a different HSC type.

Adding the HSCMain Function Block

Step	Description
1	Select the Libraries tab in the Software Catalog and click Libraries. Select Controller > M218 > M218 HSC > Counter > HSCMain in the list, drag-and-drop the item onto the POU window.
2	Type the Main type instance name (defined in configuration) or select the function block instance by clicking: Using the input assistant, the HSC instance can be selected at the following path: Global Variables > <MyController> > Embedded Functions > HSC.

Description

Select the Libraries tab in the Software Catalog and click Libraries.

Select Controller > M218 > M218 HSC > Counter > HSCMain in the list, drag-and-drop the item onto the POU window.

Type the Main type instance name (defined in configuration) or select the function block instance by clicking:

Using the input assistant, the HSC instance can be selected at the following path: Global Variables > <MyController> > Embedded Functions > HSC.

I/O Variables Usage

These tables describe how the different pins of the function block are used in the mode Event.

This 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	Not used.
EN_Compare	BOOL	Not used.
EN_Out0	BOOL	Not used.
EN_Out1	BOOL	Not used.
F_Enable	BOOL	Forces the Enable condition. Takes priority over EN_Enable input.
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. NOTE: EN_Compare, EN_ReflexO, EN_Reflex1, F_Out0, F_Out1 remain operational while SuspendCompare is set.

This 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 Administrative function blocks.
Error	BOOL	TRUE = indicates that an error was detected. HSCGetDiag function block may be used to get more information about this detected error.
Validity	BOOL	TRUE = indicates that output values on the function block are valid.
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 1 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.
