diogki Posted May 31, 2017 Report Share Posted May 31, 2017 Hello. I encounter a problem and i would like your help fixing it. I have a v1210 PLC , one EX-D16A3-RO8 and one snap-in module V200-18-E6B. I have connected two flow turbines to the two HSC inputs of EX-D16A3-RO8 and the other two flow turbines to the two HSC of V200-18-E6B. In hardware configuration i have linked MI0 and MI1 to the two turbines of the snap-in module. MI2 and MI3 are linked to the two turbines of the EX-D16A3-RO8 module. Every 10 seconds i multiply every HSC MI by 360 (10x360=3.600 seconds = 1 hour) beucause i need the flow in lt per hour (you see 36000 and not 360 because in the division the factors normally have two decimal digits, so i multiply by 100 and remove the decimal point). Then i divide with the Kv factor (according to the turbine manual - Kv is the amount of pulses for every lt) and the final outcome is the instant flow. The problem is that while the flow from two turbines that are connected to EX-D16A3-RO8 are not peaking, the two turbines that are connected to V200-18-E6B are peaking every few seconds from 4.500lt/h to 12.000-13.000lt/h and back again to 4.500lt/h that is the real flow. I have checked the turbines and they don't have a problem. Maximum input is 1.000 pulses every second. Are there any suggestions? Thank you in advance Quote Link to comment Share on other sites More sharing options...
