Programming the Main Type

Overview

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

NOTE: At build time, 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	Select the Libraries tab in the Software Catalog and click Libraries. Select Controller > LMC058 > LMC058 Expert IO > HSC > HSCMain_LMC058 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> > PLC Logic > IoConfig_Globals.

Description

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

Select Controller > LMC058 > LMC058 Expert IO > HSC > HSCMain_LMC058 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> > PLC Logic > IoConfig_Globals.

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	When EN input is configured: if TRUE, authorizes the counter enable via the Enable input.
EN_Preset	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_Preset	BOOL	Forces the Preset condition. Takes priority over EN_Preset input.
F_Out0	BOOL	Not used.
F_Out1	BOOL	Not used.
ACK_Modulo	BOOL	Not used.
ACK_Preset	BOOL	On rising edge, resets Preset_Flag.
ACK_Cap	BOOL	Not used.
SuspendCompare	BOOL	Not used.

This table describes the output variables:

Outputs	Type	Comment
HSC_REF	EXPERT_REF	Reference to the HSC. To be used with the EXPERT_REF_IN input pin of the Administrative function blocks.
HSC_Err	BOOL	TRUE = indicates that an error was detected. EXPERTGetDiag 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.
Run	BOOL	Not used.
TH0	BOOL	Not used.
TH1	BOOL	Not used.
TH2	BOOL	Not used.
TH3	BOOL	Not used.
Modulo_Flag	BOOL	Not used.
Preset_Flag	BOOL	Set to 1 by the preset of the counter.
Cap_Flag	BOOL	Not used.
Reflex0	BOOL	Not used.
Reflex1	BOOL	Not used.
Out0	BOOL	Not used.
Out1	BOOL	Not used.
CurrentValue	DINT	Current value of the counter.
