The digital input shows that it has detected something by the light glowing.However the voltage is randomly fluctuating(few mV) when the PIR detects and does not detect an object.I guess a change of few mV can just be considered some kind of noise?

When i connect the PLC to the laptop and transfer the program it says check error with PLC id. And Tri-logic gets hung.Also it restarts my computer sometimes. I connected it to the digital input and used the Testbit instruction(X=(testbit[1],2)).However it does not show me any change in the output of the sensor.When i use a mutlimeter to check the output of the Sensor it seems to be working fine (with 10 ohm output when it doesnt detect anything and Overload when the PIR detects and object).

Technical support / Help with Sensor Interfacing
« on: April 27, 2011, 07:30:13 AM »
I need to interface a PIR sensor to the FMD88-10.The output is a normally closed relay.Would i need to interface this to the digital or analog input in the PLC?Also do i use the TESTBIT function to read the output of the Sensor? If not how should i read the sensor outputs?

I have been looking online for a smoke and a fire sensor which can be interfaced with the FMD88-10 plc. It would be of great help if anyone of you could let me know which fire and smoke sensor is compatible with the inputs of this PLC. Also how can i interface this sensor with the PLC
Kind Regards,

Technical support / Learning to interface different sensors with PLC
« on: April 21, 2011, 02:11:00 AM »
Hello i am new to the world of PLC and would want to learn how to interface different sensors with FMD8810(which i have bought).It would be very helpful if you had any example`s of work you guys have done which i could go through and learn.
Thanks.
Thanks.
