Posted 22 Sep 2020 Good day all, I recently working an assignment to read analog data from sensors. I connected everything just as what the manual for sensor stated. My PLC is DVP20SX2 and the sensor data i want is 4-20mA. The analog sensor has two wires, Analog Output + and Analog Output GND. I connected the + to I0+ and the GND to the VI0-, but when I work online using the ISPSoft, I can't get any data. My doubt is the wiring. Can anyone guide me on this? Is my wiring wrong? does analog works the same as digital, where we have to connect to same COM? Share this post Link to post Share on other sites
Posted 23 Sep 2020 Hi, For mA, (V0-->I0+), (V1+-->I1+), (V2+-->I2+), (V3+-->I3+), ARE JOINED TOGETHER RESPECTIVELY. ALL THE VI0-,VI1-,VI2- & VI3- CAN GROUND TO COMMON OR INDIVIDUALLY CONNECT TO NEGATIVE SIDE. TESTED WITH AMPERE INJECTION. CANNOT ATTACHED ANY FILES FOR VIEWING.
