Hello, i'm trying to display the following analog sensor values within my program: 1. 0-10V -50 to 50 *C Temperature Sensor, on input I1 (AI3) 2. 0-10V 0-100 Humidity Sensor, on in put I7 (AI1) 3. 0-10V 0-100 Humidity Sensor, on in put I8 (AI2) 4. PT100 Temperature Probe, on AI5 Eventually i'll add a second PT100 probe to AI6, but i haven't got it yet. The sensors are used for triggering different Outputs and also control Analog Outputs to Inverter Drives, not working yet. But i'm more concerned with getting the Analog Inputs working correctly yet. I'm using LSC v8.2.1, firmware on my Logo has just been updated to the latest, it's a Logo! 6ED1052-1HB08 0BA0. i'm also connecting a KTP700, which is communicating fine and i'm slowly building the screens and interactions to the Logo!. For now, i'm really struggling to get the Logo! to read the analog inputs. Currently i have measured the following real Voltages: 1. AI3 = Logo = -500, actual voltage 4.77V 2. AI1 = Logo = 290, actual voltage 5.29V 3. AI2 = Logo = 0, actual voltage 5.19V 4. AI5 = PT100, Logo = -500. The sensors work fine when connected to my other S7 System, i should be reading roughly 22 *C on the Temperature probes (AI3, AI5), and ~ 55 Rh on the Humidity Sensors AI1 & AI2. Can anyone suggest what's going wrong? My program is attached. Thanks in advance. Andy AttachmentFruit Biltong.zip (360 Downloads) |
