  1. The PCM301 is a co-processor module used to run either BASIC or "C" programs written by the developers. I do not recognize that file name, are you sure it is not written and supplied by the developer? You may want to check with the compressor manufacturer.

  2. If the cable is correct, you should veriy IC200CBL500 should verify the USB to Serial device works with PME and the SNP protocol. If those check out it is likely that the port on the PLC has had one or more of the parameters changed by the developer. Did you check documenttaion? I have seen parity changed to "none" and the baud adjusted to match a modem, usually 9600 baud. If the cable was custom made, my bet is there.

  3. If the problem is not where Steve suggests please tell us: What is the PLC part number? What port on the PLC are you using? What is the part number or pin-out of your cable?

  4. How old are you looking for? I have two sets of 3.5" floppies with LogicMaster 90-30/20S "Serial Software Package" Ver. 4.50 IC641SWP306J and Ver. 5.01, SWP306K I may be able to part with one set. What do you have to trade? I'm in need of a 12 VDC GE-IP (Fanuc) Micro 14pt or Nano PLC, prefer DC-DC but DC-Relay would do?

  5. File Name: File Submitter: RussB File Submitted: 17 Nov 2014 File Category: PLC Sample Code There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>( Click here to download this file

  6. Don't know anything about a Twedo, but you may want to look into two PID loops whos outputs go into a third PID loop that drives both proportioanl valves? Of course that would mean that all mechanical and hydraulic parts of each cylander are nearly identical, and stay that way. Or better yet get two hydraulic servo valves that can be setup as master and follower.

  7. I no longer have that manual in hard copy and the digital version never included that page. You can get all of the same information from LM90 with the Ctrl-H & Ctrl-K key strokes, do a screen capture and print it.

  8. The sensor type will be dependant on: * material the tubes are made of * size of the tubes * the 'environment' how hot are the tubes * how far away or close can the sensor be mounted, or how much room is available * must you verify a minimum or maximum number of tubes (There may be other parameters needed to be taken into consideration also.)

  9. Forget about the names matching up as some hardware manufactures interpret this different from others, there does not appear to be a clear standard. Here is how I keep it straight in my mind. An NPN input will switch the Negative or 0-Volt line of the DC circuit. A PNP input will switch the Positive or 24-VDC line. An NPN device will need to be installed to switch the Negative or 0-Volt side of the supply lines. A PNP device will need to be installed to switch the Positive side of a 24VDC circuit.

  10. You should have told the whole story up front. Please contact your local supplier for help.
