  1. S7-200 w/ TP177

    Hello, all. I'm a bit new to PLC programming; I can debug and read through things well enough, but I'm attempting to do something from scratch. I'm using a S7-200 PLC with a TP177 HMI. I was hoping someone could provide me material on how to start doing a project. Or at least, point me in the direction to find some good material. All I basically want to do is be able to start/stop a system, and then be able to record the data (from IO field template boxes) with its reference port on the PLC. I don't think it's that complicated, but not sure where these things are in WinCC flex. If someone could help me find out, that would be great.
  2. Hi, all. We have a few ML 1761 PLC around, and I was wondering if I could use these as a data acquisition unit. They would take a 0 - 5 V DC signal and I would just want them stored somewhere, like Excel? Is that possible? If so, then please advise.
  3. ML 1761 Checking Analog Signal

    Ken, Thanks for the clairifcation and help. I should be able to put the 0 - 5 V DC input into the discrete input though, correct? I'll refer to the manual that you have recommended regardless to read and learn. Is it possible to show me an example of one input within ladder logic? If an input is above the 15603 counts, then it send a signal to 'switch' a relay? How would the output signal be, is what I'm asking to learn I think.
  4. Hello, all! I'm new to PLC programming (they don't teach you it in college!), and I'm trying to program a MicroLogix 1000 unit, specifically a 1761 with 20 analog inputs. I need help knowing how to program the unit. I have 8 analog signals, 0 - 5 V DC, and I'd like to know how to check if the analog signal is 5 volts or even above 5 volts. So if the signal at the analog input is 5 volts or above, then the output will send a signal (which will actually connect to a switch to turn off a power supply). If someone can help me with this, that would be great. Also, does the unit record data?
