My to be done project consists in: two valves, two flowmeters, a PLC and KTP400 HMI. I use a PLC Simatic S7-1200, CPU 1212C DC/DC/DC and I must connect on the inputs two flowmeters from Endress & Hauser, type Promass 80 F. I use frequency outputs from flowmeters, maximum frequency = 1 kHz .I mention that I'm new to TIA Portal and this is my first project with a Siemens PLC. I kindly ask you to help me read the flowmeters on my PLC inputs. On what I read I know that I must use two CTRL_HSC and configure them on frequency. I attached my attempt to read the inputs, I added also Move function to transfer the values and read them and two compare functions if the current value equals a preset value to activate the output so I could stop the installation. I don't know if what I tried to do is correct so please help me to complete this project. After I finish this project, I will improve it by adding totalizers for each flowmeter and a manual start/stop from HMI on both valves. Thank You in advance. AttachmentProject1a.zip (36 Downloads) |
