IctudDownState()
IctudDownState() returns the lower-limit completion state of the Up/Down counter.
bool IctudDownState(uint8_t counter_id)
Commands
| Command | Arguments | Return Value | Operation |
|---|---|---|---|
IctudDownState(counter_id) | uint8_t counter_id — Counter number. Supports 0 ~ 255, the uint8_t range | bool | Returns the lower-limit completion state of the Up/Down counter. |
Example
bool Ictu(uint8_t counter_id, bool CU, bool RESET, int32_t PV); bool Ictd(uint8_t counter_id, bool CD, bool LOAD, int32_t PV); bool Ictud(uint8_t counter_id, bool CU, bool CD, bool RESET, bool LOAD, int32_t PV); int32_t IgetCount(uint8_t counter_id); void IsetCount(uint8_t counter_id, int32_t value); bool IctudDownState(uint8_t counter_id);
Precautions
- The previous fixed 0~31 restriction has been removed. However, the argument type is
uint8_t, so the maximum ID is255. - If insufficient memory prevents allocation of counter state, counter commands return
falseor0. - Once created, counter state is retained while the program runs.
