Khoukou posted a topic in Other PLCsI am using DVP-ES2 PLC with DVP04AD-E2. I connected the flowmeter to the analog input module (4-20mA). And I noticed something weird, when the flowmeter shows 4mA value (no water flow at all) the data in the PLC keeps coming like 20-30 (0-32000). And when I change to the other port of the analog input , it even reaches value like 100 although there is no water flow at all. Note: I have done proper scaling to Liter/second and do proper grounding. Do you know what is the cause of this?
