  1. 1769-IT6

    Hi all. I have a 1769-IT6 thermocouple/mv input module. It is connected to a micrologix 1500 unit. The green okay light illuminates on power up, but after you download the program and put it in run mode the processor faults. Terminal block with the cjc's are on the unit. The error message just says the I/O module has encountered an error. The hex code under status bit 6 is 179h. This error code is not in the manual. Has anyone else encountered this? Oh and I only have channel 0 enabled for type k thermocouple. Has anyone else had this issue, or know if it is a configuration issue. Any help would be appreciated. Thank you. 
  2. Hi and thanks for youre time  I am a newbie trying to connect to a 1769-L30ERMS using an Ethernet cable. I am using Studio 5000 and RSLinx Classic lite for programming and communication. However Studio 5000 and RSLinx Classic lite are installed on av virtual machine using VMware.  So my problem is two fold. Connect the VM so that it reads from the real computers ethernet port Find and communicate with the PLC from the VM There are guides on how these problems are addressed seperatly. For example https://www.youtube.com/watch?v=JdArYVceO1I and https://www.youtube.com/watch?v=ERLTvcBBK_w however I have not been able to get them to work together. So I was wondering if you, the sages of PLC programming might have some tips or trix that I could test or perhaps even a guide for how to do? Mvh Eric
  3. Dear Experts I have Compact Logix L33ER processor for Hot Backup Redundancy Purpose in WTP application. Iam using Flexlogix 1794-OB16 DO outputs. Flex adapter for IO communication. Iam trying for Soft Redundancy from main processor to peer and peer to main processor . During Switchover from Main to Peer and Peer to main Processor, the DOs are cut off. While in the middle of the process if the Switchover of PLC happens due to failure of Main or Peer PLC, if the DOs are cut off, Should i Start the process sequence logic from beginning? I tried configuring the DO properties of  Communication Fail Behavior in output modules properties as "Hold Last Output but still the DOS are cut off during switchover. Then also Iam facing the problem of DO cutoff whle switchover. Iam having same program and IO configuration in main and peer plc generated through HotBackup tool. Please let me know if there is any way to Prevent DO cutoff while switchover . Also in Panelview HMI iam using 2 screens for Main and Peer PLC. While switchover the screens in HMI are showing in boxes. Please advise. Regards Krithik.K
  4. I am looking help with an issue I have trying to connect to a 5370 Controller 1769-L33ER. The controller firmware is 20.014 and my studio does not have 20.014 firmware. I have downloaded the firmware and do not know how to get it extracted to my PC. Any help with this will be grateful.  Regards
  5. tldr: How can I release/close CIP connections to a 1769-L35E CompactLogix (rev. 17.12)? Starting having communications issues with the controller out of nowhere - no recent changes, been running for years, etc. Tag update rates on the Wonderware InTouch sessions are really slow and could not get online with the controller until the Wonderware DAS was disabled, thereby freeing up a connection. Max number of allowed CIP connections is 32, but, per Task Monitor, there are 35 active connections. How can I drop all CIP connections so that only the valid ones come back? Anyway to do it without cycling power or going from run->prog->run? There are a number of cached message blocks, a  1794-AENT FlexIO Adapter, 10 other generic ethernet devices, and the connection to the WW DAS.   Thank you for your help.
  6. Hello Im using a 1769 HSC card with a L35E and trying to get the RPM. Ive been reading through forums for a couple days trying all the ideas from people who have had similar issues but I still cant get the current.rate(x) working.  Im using a single channel encoder at 60ppr. I believe the card is set up right and the channel is enabled. The counter seems to work fine but the rate stays 0 when im spinning the encoder slow but will jump to  100 or 200 if I spin it fast.  Any help would be appreciated. Thanks
  7. Looking for some help that i cant seem to find online - I have a  CompactLogix 5370 L1 Controller part number 1769-L16ER-BB1B and would like to connect a 1769-IF4 and a 1769-OF2 Analog expansion modules. Rockwell sales tell me they are compatible The Compactlogix looks to be a "slide in" and the expansion modules are Plug Type. Is there a cable or base rack I can use? Thanks in advance.
  8. 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
  9. Hello forum! I'm using AB Compactlogix 1769 L35E CPU energized by 1769-PA2 power supply which is also supplying to 1769-SDN DeviceNet scanner, both via backplane. Trying to build a simply DN network connecting the scanner to a Balluff BNI DNT-104-000-Z004, which is a 16 PNP digital input block, since is only input module I rely that no extra power supply will be required. The problem is that when connecting both scanner and input block via my DN thick cable (Balluff BCC07YY), the input module does not energize. In fact I got no voltage reading when measuring voltage between scanner V+ and V- terminals. I measured voltage at 1769-PA2 power supply DC output (which is not in use) and its providing 24VDC, also scanner is powered on so I do not think the problem could be power supply nor backplane. Scanner display shows 92 number, scanner manual says that 92 error is "no devicenet power" and has the following description: No network power detected on DeviceNet port. Provide network power. Make sure the module drop cable is providing the proper power to the DeviceNet port. Which I do not get, is not the power supply from 1769-PA2 via backplane enough?  Is not the scanner supposed to provide voltage to the network? I've no grounding connection connected to PE yet (just between devices GND terminals)... is that a problem for testing this small network? It will be done soon but now I'm waiting for cable material. Actually I'm online using Studio5000 and have 1769-SDN DeviceNet scanner device declared at the project, there is no warning nor major fault displayed from the software. Thanks for reading.
  10. I need to run 4 exactly same devices with 4 different controllers. The logic for them would be exactly the same but the IPs and controller names would be different. Is there a way to do it using 1 project file? Basically whenever download is done the logic would be downloaded but the controller name/IP would be left unchanged. They will be connected to the same network so the IPs must be different. I am using 1769-L32E for these and all racks are set up exactly the same. Any ideas?
  11. Has anyone used a 'Spectrum 1769sc-IF4IH' hart card?  I am currently using studio 5000 vr 24.
  12. 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?

  15. 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?
  16. 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.
  17. 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
  18. 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
  19. 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.
