The IC697MDL671 Interrupt input module is designed for systems using DC power and offers 16 inputs for a variety of applications. The input is divided into four groups. Each point is labeled with an alphanumeric code A1 through D4. It should be noted that the last two inputs in the last input group are used for configuration purposes. IC697MDL671 Interrupt the input module works at 24v DC and the isolation rated voltage is 1500v. The voltage ranges from 13.5 V to 30 V when the module is powered on. The opposite voltage range (off state) is a positive logic of -3 to 5 volts and a negative logic of -5 to 30 volts. In addition, when the module is turned on, the rated current is 6 to 15ma, and when the module is turned off, the rated current is 0 to 2ma.
Working principle
The working principle of an interrupt input module usually consists of the following steps:
Signal detection: The IC697MDL671 interrupts the input module to continuously detect the status of the external signal input port.
Interrupt trigger: When the signal that meets the interrupt trigger condition is detected (such as signal level change, pulse signal, etc.), the interrupt input module sends an interrupt request to the processor.
Interrupt processing: After receiving the interrupt request, the IC697MDL671 processor will suspend the current main program execution, and jump to the corresponding interrupt service program for processing according to the interrupt number.
Return to main program: After the interrupt service program is completed, the processor returns to the location where the main program was interrupted and continues to execute subsequent programs.
Fourth, implementation methods
The IC697MDL671 interrupt input module is implemented in a variety of ways, depending on the specific hardware platform and software architecture. Here are some common implementations:
Hardware interrupt: A specialized hardware circuit detects an external signal and sends an interrupt request to the processor when the signal meets the conditions.
Software interrupts: In some cases, external events can also be handled by software simulating interrupts. For example, in polling mode, the main program periodically checks the status of the external signal and executes the corresponding interrupt service procedure when it finds a signal that meets the interrupt condition.
