  1. CompactLogix Hart

    Has anyone used a 'Spectrum 1769sc-IF4IH' hart card?  I am currently using studio 5000 vr 24.
  2. Hi there, is somebody experience whereby the output of the 1769-OF4Ci is not responding on the value entered?.  Setting: 4-20mA Res: 0- 32767 - PID set whatever value I key in the output current remained.  please help. Ganie
  3. Compact Logic 1769

    I have just started programming PLC's and the first thing I have came up against is a 4-20ma signal to a analog card for a Turbidity meter. The problem I am having is the reading is very erratic. Is there any way to get it from jumping around so much?

  6. First post. We recently upgraded our machine from an SLC to compactlogix. In the SLC 5/05 we used analog 1746-ni8 cards for pressure and position sensors. When we moved over to the compactlogix 1769 l36erm with 1769-if16c cards we seen issues where the analog values had very little definition accuracy. This can be resolved by changing the filters but then the response time of the card is to slow and we miss data. All of the relevant code from these sensors are in their own task and ive tried periodic, event and continous tasks but none of this helps. The strange thing is with the SLC we never seen these issues. Any ideas how i can improve the reponse time when the filters are set low?
  7. Speed/ Velocity Calculation

    Hello, I hope you are all having a great Wednesday.  So I was wondering if this is possible, and if so, how to do it.  What I'm trying to do is get a real time speed of my hydraulic cylinder using a transducer, a 1769-HSC high speed counter module, and a 1769-L36ERM processor.  Kind of like a speedometer in my car.  I would like the number in inches/ second.   We use a hydraulic proportional valve to control a cylinder that we use to pump molten lead into our die cast machines.  Back in the day they used to use limit switched that rest on a tail rod attached to the cylinder shaft to get an approximate stroke length.  It was very crude, but it worked for what it was.  I'll explain  a little more, in case I'm not explaining it very clearly.   So on most of our machines the maximum stroke length of a normal shot is about 11".  We have different "stages" to the shot.  Stage one is typically from 0" (when the shot is all the way returned) until about 1.5", at 1.5" the valve stops and there is a shot delay for 1 second (vacuum draws some lead into the goose neck and into the beginning of the mold), after the delay second stage starts, second stage is from 1.5" to 4", third stage is from 4" to 8" and fourth stage is from 8" to 11.5" or until the shot timer finishes timing, and then another valve switches, and the shot starts it's return.  We have the different stages because we typically shoot the cylinder slower at first, and then delay and then almost maximum velocity.  We control the velocity with an analog output to a solenoid on a hydraulic valve.  For example, for the first stage we may open it up 20%, then 0% during the delay and then 85% during second, third and fourth.  Sometimes we play around with different shot delay times, different shot velocities, sometimes 3rd may be faster than 4th, ect, to get the best die casted parts.   Anyways, so in the past they would use limit switches.  One was a button head style that when the shot cylinder shaft was all the way returned, it made the switch, and we knew the shot was fully returned.  One was set at 1.5", 4", 8" etc.  They all, except for the shot return switch, were roller style limit switches.  They were all made, and once the shot reached that stroke length, they would come off the rod and we would know we were in that next stage.  So it was very crude.  If you wanted to adjust the stages you would have to climb up on top of the very hot molten lead pot, mark where the limit switch currently was (in case you needed to put it back) loosen the bracket, try to make a measurement and guess how far you moved it.  It was crude to say the least.  Some of our older style machines that don't need much tweaking still use the limit switch style positioning system.   Most of our new machines all use a VisiTrak transducer.  The shot cylinder rod that is attached to the cylinder shaft is actually threaded and then has a very thing layer of chrome plating.  The transducer sits against the shaft and counts the threads.  It transfers those counts to a Very High Speed Counter module in our PLC I/O rack.  We have a CompactLogix L36ERM processor and we use a 1769-HSC as the VHS Counter.  Then we just do some math in the PLC program and we are able to get shot stroke in inches.  We set different compare instructions, for example when: Shot_Stroke is greater than or equal to 0 AND Shot_Stroke is less than or equal to 1.5 then 1st_Stage_Bit is active.  We set up different numbers for all the different stages and still use the button head limit switch as a second method to confirm that the stroke is fully returned.   The counter is very fast.  We are able to know what the shaft stroke is at any given point.  We currently do some math using the distance of each stage and using timers to calculate inches per second of each stage.  That way we can have a nice Speed number in inches/second that we can use to make different adjustments to the shot.  Typically the first stage is about 7"/second second is: 24"/second third is: 42"/second and fourth is 2"/second.  But I want a real-time, current speed, not just the speed that it traveled through each of the stages.     Ok, after all of that explaining, I'm finally getting to my question.  How would I logically write a set of instructions that could give me current speed in inches per second.  Like i said, I am able to calculate the speed of each stage, after the shot has completed the stage, I just divide the distance of the stage (in inches) by the time it took to travel through that stage (in seconds).  But I would like to have a real time speed, kind of like a speedometer on a car.  Is this possible?  I know that the scan time on this processor is very fast and the high speed counter module counts very fast as well.  How do I do the math to get a real time speed in inches/ second?   Sorry for the very long post.  I just thought i would give you a background on what we are doing/ would like to do.     Thank you very much.
  8. Hello, I am trying to get a Fanuc R-30iB controller added into my RSLogix program. The PLC is a CompactLogix 1769-L30ER When I search for new modules to add I see a pre setup Fanuc Robot Ethernet module, but I can't get that to work. I tried following Fanuc's instructions and setting it up as a generic ethernet module, but I couldn't get that to work either, it just says i/o not responding for that module. I am definitely able to ping the Fanuc controller, so I believe I am seeing it. When I add the controller in RSLinx, it's there, but there is no icon next to it's name. I'm guessing because its a fairly new controller, and it came out after the version of RSLinx that I'm using? Don't I need to download the EDS file for the new controller so that Linx can recognize it? Any help would be greatly appreciated. Thanks
  9. Error in 1769-SM2

    Dear All I have a PLC and a 1769-SM2 so the red led is Steady Red. in manual wroted about this error : Cause:The module is unable to establish communication with the controller. Corrective Action: Cycle power to the controller. now I want know what it means to Cycle power to the controller? means is I power off the controller and then power on it? if it is I do it and the problem exist. could you help me on this issue? Best Regards 1769-SM2.pdf
  10. Power plant application.

    Hi all, I am using compact logix 5370 L3 controller(1769-L30ER) in hydro power plant application. So I have to now fetch electrical parameters from different brand component i.e. Siemens make General Management Relay which has profinet communication support. So the question now, is it possible to communicate directly with the controller and Siemens relay to display various electrical parameters? If not please suggest me what I can do to communicate with the relay in order to display the parameters in HMI. Awaiting for the replies. Thank you.
