The interrupt function of Omron CP1 series PLC and the establishment of interrupt program
Since the main program of the PLC is the working mode of cyclic scanning, some more urgent special tasks (interrupt subroutines) that occur randomly must be executed immediately without being affected by the scanning cycle, and the CPU temporarily aborts the main program and executes the interrupt subroutine, so the working mode is the interrupt function ...

Introduction to the classification of Omron relay switch contacts
1.A contacts
A contact is a contact in which the two contact terminals are separated (OFF) when the switch is not operated, and closed (ON) when the switch is operated. If you want to start the load by operating the switch, you can use the A contact. A circuit is a circuit that uses a contact without operating the switch (pressing ...

How does Omron PLC input the rising/falling edge?
The first
1. First of all, we open the CX-P software, set the PLC model, enter the programming section, and prepare for programming.
2. Usually when we program, we are used to entering LD instruction programming, when we need to input the rising edge, we need to enter @LD0.00, you can.
3. Down...

How are Omron switch relays wired?
One. Before connecting, determine the voltage required for the proximity switch, and in the case of a 3-wire system, determine whether it is PP type or P type. The proximity switch is divided into 2-wire, 3-wire and 4-wire systems.
Two. Wire proximity switches are connected in series when connected to relays. i.e. the relay is connected to the proximity switch to give it ...

Introduction to Omron travel switches
Omron travel switch, position switch (also known as limit switch), is a commonly used small current master electrical appliance. Through the collision of the mechanical moving parts, the contact movement is realized, and the connection or disconnection of the control circuit is realized, so as to achieve a certain control purpose. Usually, this kind of switch is used to limit the ...

There are four main characteristics of Omron PLC
1. High reliability
The PLC replaces a large number of intermediate relays and time relays in the relay control system with software, and the wiring can be reduced to less than one-tenth of the relay control system, which greatly reduces the possibility of poor contact contact. In addition, the PLC itself has a strong self-diagnosis ...
