Working Mechanism

  • These relays use a microprocessor to control and monitor the inputs and outputs of the system.
  • Operator can program the relay using the included software, which allows them to create a logical control system using basic logic and functions.
  • The program is then stored in the relay's internal memory and executed by the microprocessor.
  • The microprocessor monitors the inputs and executes the programming logic which determines the state of the outputs, such as turning off a motor if a temperature sensor reaches a certain limit.

Frequently Asked Questions

How to troubleshoot PLCs?

Initiate by checking the input / output status and the program execution. The information on error codes or internal status can be found in the PLC manual, the PLC software or the controller's diagnostic LEDs to fix the relevant issue.

What is the function of counters in a PLC?

A counter is a digital device that counts events or pulses in an application. The PLC counter consists of two main components: A counter register, which stores the count value and a counter instruction, which makes an increment in the count value in response to specific events or inputs. The counter can be programmed to count up, count down or count up to a specified limit and then reset to zero.

How to install the Easy500 PLC?

  • Install the PLC in a control cabinet, service distribution board or an enclosure so that the power supply and terminal connections cannot be touched accidentally during operation.
  • Mount the PLC to the surface using the provided screws or other mounting hardware.
  • Connect the device to a power source using the correct voltage and current ratings for the specific model.
  • Connect the inputs and outputs to the PLC using the wiring diagram.
  • Install the programming software on a computer, following the manufacturer's instructions.
  • Use the programming software to create and upload the control logic to the PLC. Make sure to test the program and debug any issues.
  • Test the PLC to ensure all inputs and outputs are working as expected.
