A Simple type counter is always managed by an HSCSimple_M241 function block.
NOTE: At build time, a detected error code is given if the HSCSimple_M241 function block is used to manage a different HSC type.
Adding an HSCSimple Function Block
|
Step |
Description |
|---|---|
|
1 |
Select the Libraries tab in the Software Catalog and click Libraries. Select Controller > M241 > M241 HSC > HSC > HSCSimple_M241 in the list, drag-and-drop the item onto the POU window. |
|
2 |
Type the Simple 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: <MyController> > Counters. |
The tables below describe how the different pins of the function block are used in One-shot mode.
This table describes the input variables:
|
Input |
Type |
Comment |
|---|---|---|
|
Sync |
BOOL |
On rising edge, presets and starts the counter |
|
ACK_Modulo |
BOOL |
Not used in one-shot mode. |
This table describes the output variables:
|

Type |
Comment |
|---|---|---|
|
HSC_REF |
Reference to the HSC. To be used as input of Administrative function blocks. |
|
|
HSC_Err |
BOOL |
TRUE = indicates that an error was detected. Use the EXPERTGetDiag function block to get more information about this detected error. |
|
Validity |
BOOL |
TRUE = indicates that the output values on the function block are valid. |
|
Run |
BOOL |
Set to 1 when the counter is running. Switches to 0 when CurrentValue reaches 0. A synchronization is needed to restart the counter. |
|
Modulo_Flag |
BOOL |
Not used in one-shot mode. |
|
CurrentValue |
DWORD |
Current count value of the counter. |
