Hello, I have a JZ20-R16 plc and a Aplisens 4-20 mA level transducer. I do linearization in ladder to get the correct level value in meters. Depending on the level the plc starts and stops a pump, and it all works greate. Start and stop levels are input by the user from keypad, also the max value of the transducer. Everything works ok, the problem is with displaying current level on lcd. Right after linearization i copy the value to MI3 that is set to be shown on the "main" screen. It is displayed but the readout is jumping around/changing very quickly (level is constant), numbers
Hi, I have OPLC V350-35-TA24 what includes onboard I/Os and configurable via wiring 2 Analog, 2 PT100/TC, and 1 HSC/ Shaft-encoder Input. So, first, i made changes in hardware project where analog input 2 and 3 were 0-10V, I connected them with potensiometer (i used voltage divider, so to analog input went 0,33-11,5 VDC, pot supply camed from same supply as OPLC +24VDC, pot signal went to analog input, pot ground went OPLC 0V). I also changed jumper setting, input 5 (analog input 3) - JP4 B, JP10 A, input 6 (analog input 2) - JP8 B, JP9 A. I made new project were was only linearization b
