HSC Interrupt parameters
The HSC interrupt parameters are used to configure the start and mask options.
Auto Start (HSC0.AS)
Parameter | Data format | HSC modes | User program access |
|---|---|---|---|
HSCO.AS | Bit | 0...9 | Read-only |
Auto Start is configured with the programming device and stored as part of the user program. The auto start bit defines if the HSC interrupt function automatically starts whenever the controller enters any run or test mode.
Overflow Mask (HSC0.MV)
The MV (Overflow Mask) control bit is used to enable (allow) or disable (not allow) an overflow interrupt from occurring. If the bit is clear (0), and an Overflow Reached condition is detected by the HSC, the HSC user interrupt is not executed.
The MV bit is controlled by the user program and retains its value through a power cycle. The user program must set and clear the MV bit.
Parameter | Data format | HSC modes | User program access |
|---|---|---|---|
HSCO.MV | Bit | 0...9 | Read-only |
Underflow Mask (HSC0.MN)
Parameter | Data format | HSC modes | User program access |
|---|---|---|---|
HSCO.MN | Bit | 2...9 | Read-only |
The MN (Underflow Mask) control bit is used to enable (allow) or disable (not allow) an underflow interrupt from occurring. If the bit is clear (0), and an Underflow Reached condition is detected by the HSC, the HSC user interrupt is not executed.
The MN bit is controlled by the user program and retains its value through a power cycle. The user program must set and clear the MN bit.
High Preset Mask (HSC0.MH)
Parameter | Data format | HSC modes | User program access |
|---|---|---|---|
HSCO.MH | Bit | 0...9 | Read-only |
The MH (High Preset Mask) control bit is used to enable (allow) or disable (not allow) a high preset interrupt from occurring. If this bit is clear (0), and a High Preset Reached condition is detected by the HSC, the HSC user interrupt is not executed.
The MH bit is controlled by the user program and retains its value through a power cycle. The user program must set and clear the MH bit.
Low Preset Mask (HSC0.ML)
Parameter | Data format | HSC modes | User program access |
|---|---|---|---|
HSCO.ML | Bit | 2...9 | Read-only |
The ML (Low Preset Mask) control bit is used to enable (allow) or disable (not allow) a low preset interrupt from occurring. If this bit is clear (0), and a Low Preset Reached condition is detected by the HSC, the HSC user interrupt is not executed.
The ML bit is controlled by the user program and retains its value through a power cycle. The user program must set and clear the ML bit.
