A Simple type is always managed by an HSCSimple function block.
NOTE: At build, an error is detected if the HSCSimple function block is used to manage a different HSC type.
Adding a HSCSimple Function Block
|
Step |
Description |
|---|---|
|
1 |
Drag the Libraries > Controller > HMISCU > HMISCU_HSC > HSCSimple 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 Simple. |
|
NOTE: This method is for ST, LD, or FBD languages. |
|
The tables describe how the different pins of the function block are used in One-shot mode.
The table describes the input variables:
|
Input |
Type |
Comment |
|---|---|---|
|
EN_Enable |
TRUE = authorizes changes to the current counter value. |
|
|
Sync |
BOOL |
On rising edge, sets the counter value with the configured preset |
|
ACK_Modulo |
BOOL |
Not used |
The table describes the output variables:
|
Output |
Type |
Comment |
|---|---|---|
|
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 the output values on the function block are valid. |
|
HSC_Err |
BOOL |
TRUE = indicates that an error was detected. Use the HSCGetDiag function block to get more information about this detected error. |
|
Run |
BOOL |
TRUE = counter is running. Switches to FALSE when CurrentValue reaches 0. A rising edge on Sync is needed to restart the counter. |
|
CurrentValue |
DWORD |
Current count value of the counter. |
|
Modulo_Flag |
BOOL |
Not used |
