Dear Users, I am a engineering apprentice for Unilever in my final year, we have only recently started to learn about PLCs and go on courses regarding them. We are currently undergoing a energy reduction drive where we want to reduce the amount of compressed air we are using, to calculate our savings I have been given the task of using a usually panel mounted Festo SFAB 600U 2SA Q10 flowmeter and mounting in a portable box. The festo flowmeter will be then wired to my CPU1214C. I have spoke to a few engineers in passing and they have basically said I am best using the analogue output on the flowmeter and wiring that to the analogue input on my AI expansion card. The 5-Pin flowmeter in question has the following wiring: Pin No: Assignment: Core Colours: 1 DC + 24V Operating Voltage Brown (BN) 2 Binary Outputs B (Out B) White (WH) 3 0V Blue (BU) 4 Binary Output A (Out A) Black (BK) 5 Analogue Output C (Out C) Grey (GY) I've tried looking at my flowmeters manual and my S7-1200 manual but nothing really gives me a nice easy to understand overview of what I need to do. I have included the; Flowmeter Manual, The S7-1200 manual, and a simple diagram of what I intend to do and how my system should look. OVERVIEW:
Sorry if this is simple, I don't believe it is though, I would really appreciate the help as I don't know where to start, I have welded a rig with DIN rail and have ordered my Power Supply. I am continuing to research how to do it but feel at this stage I need help, I don't want to damage my PLC or my instrument. Many Thanks, Luke. PS: I didn't realise I couldn't Load more than 1 attachment so have chosen to just load the flowmeter manual I have done a simple diagram below using type. ~~~air supply~~~[FLOWMETER] -----> PLC Input ----> [PROGRAM] ---> [HMI Connected through Ethernet, now displaying figures such as how much flow in 60seconds and the cost once I have typed it in]. Thanks Again, Luke. AttachmentFesto SFAB flowmeter manual 600U.pdf (231 Downloads) |

hi Luke, what exactly do you want to know from us? for connecting the sensor to the S7-1200, have a look in the manual: SIMATIC S7 S7-1200 Programmable controller wiring diagrams can be found in Chapter A Technical Data. Do you have an analogue Signal-Board or Signal-Module? Because the On-Board-Periphery of an S7-1200 only has Voltage-Inputs and your Flow-Meter has an Current-Output. once you got the value in your programm, you can use the Scale-function to get the value as a real-number, as you need it. hope this helps, regards, |
