  1. 1783-ETAP

    Hi, I've seen the 1783-ETAP being used to insert devices with only one Ethernet port into a Ring network topology. Not sure but I think it can be used to insert a device that doesn't support time stamp protocol into a network running CIP with Time Stamping.  Bye
  2. absolute motion servo motor and emergency stop

    Hi, From here it's really difficult to figure out what's happening, I can only guess that when you have an emergency stop the drive de-energizes and losses its home reference and (maybe) that is why the next movement is to move the chain to its next stop in forward direction. Another possibility that I can think of is that the emergency stop resets a sequence, in this case you have to check your program logic.  
  3. absolute motion servo motor and emergency stop

    Does the servo-drive de-energize? losses power? How do you home your axis?
  4. High speed counter

    Hi, RS Emulate 500 does not emulate the High Speed Counter which is a special circuit inside the PLC that runs independently from the scan cycle. I've read it somewhere and I'm trying to find the official paper, I'll let you know when I find it. Bye
  5. No, the file size difference is not software version related. I have noticed this differences for long time but since the compare tool shows no differences between files I have simply ignored them. I made this test: I copied a file from one location to another, edited it, made couple changes and reverted them (mostly bits from zero to one and back to zero), saved the file and got a saved file with a different size. I have always used RSLogix 500 V9.00.00 Finally I compared both files using the compare tool and the result showed no difference between both different sized files. Now, the reason why the software changes the file size when it saves it is not of my knowledge. My guess is that it has something to do with changes tracking.  
  6. SoftLogix and RSLinx Connection Issue

    I'm supposing that you're not able to open the GUI because the RSLinx icon doesn't show in the taskbar in Windows 7. I suggest to make a copy of the shortcut, edit it and add the command line: /service in the Target field. It will look similar to: "C:\Program Files\Rockwell Software\RSLinx\RSLINX.EXE" /service Save it Use this new shortcut to launch RSLinx Now the icon will show in the taskbar and you'll be able to open the GUI while running as service. Hope this helps Bye  
  7. Problem during installation of RSLogix-5

      Suggestion: Try installing and running with administrator rights  
  8. WIFI Communication to RIO

      I think this will lead you in a good direction: http://www.prosoft-technology.com/Products/Gateways/EtherNet-IP/EtherNet-IP-to-Allen-Bradley-Remote-I-O-or-DH-Gateway http://www.plctalk.net/qanda/showthread.php?t=114670 Hope this helps   Bye
  9. Usage of 8-24VDC encoder with 1746HSCE

    Hi, I just did some research for you. Encoder brand: FEMA (not Elcis) Model: XA59C12-50-824-B-B-CV-R-05 X: Custom options A: High temperature 59C: 59mm, hollow shaft, to be used on motors 12: 12mm (diameter) 50: 50 ppr 824: Power supply 8 - 24 Vdc (Can be supplied with 24V) B: Bidirectional - no Z channel B: Push-pull output (this is compatible with your module) CV: Cable R: Radial (in this case refers to the cable location) 05: 5m (cable length)  Bye  
  10. Usage of 8-24VDC encoder with 1746HSCE

    Hi man, I haven't used this module but reading in the 1746-HSCE2 user's manual 1746-um002_-en-p.pdf chapter 3 it says: "For a 12V dc encoder signal, use the 24V dc jumper setting" and in appendix A (specifications) you'll see that 12V is inside the input range but very close to the edge so you have to make sure the pulses from your encoder pass the on-state and off-state threshold levels. You haven't mention what model your encoder is. Make sure your encoder hardware and the module are compatible. Bye    
  11. DriveLogix Powerflex 700S Motion Help

    Hi, I have some questions for you: Does the drive have an HMI installed? Does it display a message like position error or something? How do you put the system back to work? Recycle power? Does the MAM instruction set the pc bit? error bit? What type of feedback device do you use, absolute or incremental? Is there a chance that coupling between the motor and the load slides?
  12. Periodic Tasks Effects on Communication

    Hi, My recommendation for you is to analyze the program and take advantage of the Task Monitor Tool to modify the program in order to avoid task overlapping which prevents tasks from executing all the code and is a source of erratic behavior. You should also reserve enough time for system overhead and reconfigure your CPU to utilize this time to serve either the continuous task (if there is one) or reserve this time for system tasks. The communication with your workstation will be served during this system overhead time. See: Knowledgebase topic 54182 and Programming Manual 1756-pm005_-en-p.pdf Most probably you will find that you can expand some task scan periods. I may be wrong but this seems to have been programmed by someone accustomed to program Siemens who didn't check the performance of this application deep enough. Bye  
  13. Hi, Is there any way to disable the little preview window that shows up when you hover the mouse on a routine tab in logix designer? I think it appeared for the first time in RSLogix 5000 V17. I don't know if anybody else is annoyed by this windows but I certainly am. Thank you  
  14. MAOC instruction Question

      I just want to tell that this project materialized and the press has been working fine since startup about six months ago. I ended up programming two separate MOAC instructions. One I utilize to generate logic bits to synchronize the press with some functions like: servos sheet advance command, product control and die protection, and the press normal stop command. The second MAOC I utilize to drive two physical outputs of my 5069-OBF module, one pushes the product out of the tool and the other expulses the product from the die. The major problem I faced was how to make the MAOC instruction drive only two physical outputs. Originally I configured the MAOC as in knowledgebase topic 853576. I only wanted bits 4 and 5 of my output module to be driven by the instruction but I got all the other bits to go "false". I struggled with this problem for an hour but since I needed to finish all the programming in a very short time I decided to use a different approach and go back to this issue later on. The different approach was to configure the Module's Output Data as "Data" (not scheduled) and drive bits 4 and 5 from my press task. The press task was configured to run every 2 msec so I estimated that this would introduce an error of 2.4 degrees while running at 200 struck/min. Fortunately this turned out to be completely tolerable. I haven't gone back to this issue so far since I need production to stop and there is no hurry to do so. Finally my question:   Has anybody had this same issue with a 5069 CompactLogix?      Ideas? Thank you
  15. Micrologix 1200R Communication port & cable

      I think you have to buy an 8 pin mini din extension cable and an 8 pin door mounted mini din connector and build the cable your own
