AH500 Module Manual 7. Bit 6 in CR4/CR32/CR60/CR88: If bit 6 in CR4/CR32/CR60/CR88 is turned OFF, ≧ is selected. If bit 6 in CR4/CR32/CR60/CR88 is turned ON, ≦ is selected. Before users select a type of comparison condition, bit 5 in CR4/CR32/CR60/CR88 must be turned ON. 8. Bit 7 in CR4/CR32/CR60/CR88: After bit 7 in CR4/CR32/CR60/CR88 is turned OFF, AH04HC-5A will not output any hardware signal if the number of accumulated pulses meets the comparison condition set. After bit 7 in CR4/CR32/CR60/CR88 is turned ON, AH04HC-5A will output a hardware signal if the number of accumulated pulses meets the comparison condition set.
Before users setting bit 7 in CR4/CR32/CR60/CR88, bit 5 in CR4/CR32/CR60/CR88 must be turned ON. The related hardware signals are described below. 9. Bit 8 in CR4/CR32/CR60/CR88: After bit 8 in CR4/CR32/CR60/CR88 is turned OFF, AH04HC-5A will not send a message which asks the CPU module to execute the interrupt subroutine specified to the CPU module if bit 3 in CR19/CR47/CR75/CR103 is turned from OFF to ON. After bit 8 in CR4/CR32/CR60/CR88 is turned ON, AH04HC-5A will immediately send a message which asks the CPU module to execute the interrupt subroutine specified to the CPU module if bit 3 in CR19/CR47/CR75/CR103 is turned from OFF to ON.
Bit 5 in CR4/CR32/CR60/CR88 needs to be turned ON before bit 8 in CR4/CR32/CR60/CR88 is turned ON. The related parameter is described below. 10. Bit 9 in CR4/CR32/CR60/CR88: After bit 9 in CR4/CR32/CR60/CR88 is turned OFF, the number of sampled pulses, the number of accumulated pulses, and the number of input pulses will not be cleared if X0.0+ and X0.0–/X0.1+ and X0.1–/X0.2+ and X0.2–/X0.3+ and X0.3– are turned ON. After bit 9 in CR4/CR32/CR60/CR88 is turned ON, the number of sampled pulses, the number of accumulated pulses, and the number of input pulses will be cleared if the external signals X0.0+ and X0.0–/X0.1+ and X0.1–/X0.2+ and X0.2–/X0.3+ and X0.3– are turned ON.
The related parameter is described below. 11. Bit 10 in CR4/CR32/CR60/CR88: If bit 10 in CR4/CR32/CR60/CR88 is turned ON, the input contact of the external signal is a normally-closed contact. If bit 10 in CR4/CR32/CR60/CR88 is turned OFF, the input contact of the external signal is a normally-open contact. 7.9.6 Operating State of a Counter [Description] Bit 0~bit 15 are described below.
