  1. Debugging FX1s Beer Bottling machine

    Thank you Steve! By setting of the watch of M111 i have figured out that X006 is not triggering the shift register. I physically moved this sensor to send its signal after X007 and now the machine operates again as it should! Problem solved. Thanks again so much for your help. Eric
  2. Debugging FX1s Beer Bottling machine

    Okay thanks, I will try that. Am I correct in seeing that the rising pulse for X007 comes before the pulse for X006? So maybe they should not be timed exactly but offset so X007 sends the signal before X006. Eric
  3. Debugging FX1s Beer Bottling machine

    Hi Nehpets, Thanks for the reply. Program is attached. So if I understand my program correctly, a pulse from sensor x007 turns m65 from 0 to 1. a second pulse from sensor x006 resets M65 to what it was. So if m65=0, then m65=0, but if m65=1 then m65=1. a signal from X006 also sets the relay m100 to 1, which in turn starts the shift of m111 towards m140. I actually don't see any other instances of m100, but m111 fires the vacuum solenoid (y001) and m113 fires the filling solenoid (y002). Thanks again, Eric 16-16-6PLC_2.rar
  4. Hello All! Long time engineer first time programmer. Any help is greatly appreciated. I have an automated Beer bottle rinser, filler, and capper that I need help diagnosing a problem. We purchased the machine in July and it ran great until a couple weeks ago when it doesn't seen to be reacting to bottles being present anymore. FX1s-30MR Here are the symptoms: When a bottle is run around the filling carousel, there is a prox sensor to detect it's presence (X007). There is also a sensor under the machine on the gears to detect timing (X006) When a bottle is detecting there is a slight delay, then the pneumatic valve for the purge fires (Y001), followed by the valve to fill the bottle with beer (Y002). Even though, the LED light on both the sensor and the I/O illuminate confirming that it is receiving the the input signal from that sensor, no output signals are being sent. My first instinct was to check all electrical connections and swap out the prox sensor just to be safe, but still no dice.... So I purchased a USB-RS422 FX cable and downloaded the demo of GX Works 2 to better try to pin point the issue. Using the monitor function on GX works 2 I can again confirm that the PLC is receiving the correct signal from X007 when a bottle is present, however the outputs Y001 and Y002 have a constant value of 0... Unfortunately this program is not simple enough for me to really understand, so maybe someone can make more sense of it than me. (see attached). Also, Not sure if its related, but when I ran the check program there is a double coil error revolving around the Beer inlet solenoid. This is to let beer into the filler bowl, not the bottle. oh and the manufacturer won't be able to help for a couple weeks when they can send a technician... Any thoughts, comments, or questions are appreciated. Cheers, Eric screenshot2.bmp screenshot1.bmp
