  1. Produced/Consumed Tag Communications Active

    Thanks for the suggestion. I'll give it a try when I'm back online next week. Looks like I should be monitoring if the EntryStatus value in the connected PLC = 16#4000. • 16#4000. Running. All connections to the module are established and data is transferring. Hope I'm on the right track!!
  2. I have shared tags between two CompactLogix 5370 PLC's using produced/consumed method. I need to confirm whether communications between each PLC is working. Is there a built-in PLC tag available that monitors communications status or must I add an ACK/NACK heartbeat tag in the produced/consumed data.
  3. Really miss the ability to have individual element properties for instructions as available in CX-Programmer. Please, please add this to Sysmac Studio.
  4. How to copy dissimilar data types - Boolean and SINT.

    I'm trying to figure out best/preferred method of handling the input assembly. Attached is 11 byte incoming data consisting of three datatypes  UINT, INT and USINT. It appears most efficient method of handling data in Logix 5000 is to convert all elements to DINT using COP command. But I'm not clear as to how the resulting DINT data will be converted or how best to utilize the COP instruction. Note I'm new to Logix 5000!
  5. I have a custom module on Ethernet/IP with an EDS import that consists of a single BOOLEAN and array of 11 SINT. How do I copy dissimilar data types [1xBoolean and 11xSINT] using Logix5000? This data will be eventually used to develop a AOI where multiple Ethernet/IP modules could be used?  
  6. I have an upcoming project that consists of a CompactLogicx PLC  with onboard I/O AND ProfiNet I/O Devices on a separate network. This is my first time attempting to connect and control via different network protocols. As best as I can tell I require a Gateway that transfers data between each network. Either the Prosoft PLX82-EIP-PNC or AnyBus AB7649 Gateways appear to be viable solutions. If anyone has used these devices would you kindly share your experiences with either of these products OR suggest other alternatives. Pros, Cons and Suggestions always welcome. Thanks B & B  
  7. Ethernet/IP to Profinet IO with CompactLogix 1769-L18ER-BB1B

    Remote I/O modules we are dealing with are solely Profinet RT [Real Time] so signals are of fast type NOT process. Unfortunately Red Lion does not support Profinet I/O on their DSP or HMI's so using Crimson software is off the table. So far I have found a number of Gateway suppliers but am trying to find best one from actual end user experiences. When studying user manuals from above vendors the Gateway configuration seems overly complex and I am concerned I will struggle to get it working. So other than the specific Gateway hardware selection, quality/response of support is really critical. Very confused as to whether Gateway should be an Adapter or a Scanner and which is simplest to configure from Logix 5000. Thanks for your response.
  8. Pulse Output - Md212

    Ignore the settings shown in your picture. Attached is very useful document. Though written for a CJ1M PLC this also applies to the MD212 module Although I do not think you should be using a relay on a high speed output!!     [268]Omron_CJ1M_Motion_Introduction.pdf
  9. Multiple encoders to CP1L-60DT-A

    1:1 Links is a quick and simple to use. You set one as a Master and the other a Slave in the PLC settings. Download setting to each PLC and BE SURE TO POWER CYCLE for new settings to take effect. 8 words CIO 3000-3007 from the Master PLC are continuously written to CIO 3000-3007 in the Slave PLC. Likewise 8 words CIO 3008-3015 from the Slave PLC are continuously written to CIO 3008-3015 in the Master PLC. ONLY WRITE DATA TO CIO 3000-3007 in the Master and CIO 3008-3015 in the Slave. ONLY READ DATA FROM  CIO 3008-3015 in the Master and CIO 3000-3007 in the Slave. And you should be good to go.
  10. Multiple encoders to CP1L-60DT-A

    You could use 1:1 Serial Links between two CP1L PLC's to exchange data. Each PLC will need a CP1W-CIF01 RS- 232C Option Board. However the CP1L-L10 does not accept this board. You would need a minimum of the CP1L-L14.
  11. Declare an Alarme

    These examples might help you learn how to manage and configure alarms: - https://www.support-omron.fr/details/programme_exemple.php?id=2017-03-10%20-%2012-05-52%20-%20966492280 https://www.support-omron.fr/details/programme_exemple.php?id=2017-03-10%20-%2011-06-53%20-%201630660386
  12. Reviewing new gantry crane application with CompactLogix and Powerflex drives. Trying to figure out whether I should utilize 755 or lower cost 527 Series Powerflex Drives for this application. It would seem that either drive can be configured as and Axis within Studio 5000. BUT I can find no relevant documentation regarding whether either drive offers the ability for anti-sway moves. Any recommendations or past experience with similar applications would be most welcome.
  13. COMPACTLOGIX MOTION WITH POWERFLEX DRIVES CRANE APPLICATION

    Hmm! Another thought. If I always move the hoist position such that the load is moved upward to the maximum z vertical position prior to any x-y moves would this eliminate/minimize anti-sway issues. i.e. Always move load up to max z, make required x-y move and then lower z-axis to desired height.Will contact RA for their ideas how to handle this issue. Thanks all for feedback.
  14. COMPACTLOGIX MOTION WITH POWERFLEX DRIVES CRANE APPLICATION

    Thanks kaiser_will. I am already familiar with the items you shared links. The AB brochure refers primarily to the hoist axis of the crane. The ABB solution and Magnetek products provide an off-the-shelf solution. In my case the customer is insisting on using Allen-Bradley. The application is for a relatively simple automated storage/retrieval system in their exiting facility.
  15. ST Language

    With INNOLALOE'S code on rungs 5 and 6. He's THE BEST!!     EdgeDetect_Example_2.cxp
  16. ST Language

    More ideas. Trigger oneshot with differentiated instruction for EN input OR handle oneshot with internal latch within ST. EdgeDetect_Example_1.cxp
  17. Though I am not familiar with Altivar drives I am sure there must be drive parameters that allow synchronizing the movement between two drives without having to do this via external from CP1L PLC's. In this arrangement typically one drive outputs an analog output to the follower drive and they both follow one another with no requirement for any PLC intervention. At the very least this would require encoder feedback signals within each drive to successfully implement. You could utilize torque or feedback position based upon requirements. With this arrangement response time is completely independent upon PLC cycle time and should be adequate for your application.
  18. Errors that appears when i connect via serial port

    Glad to help. My best guess is that with dipswitch 5 ON the default setting of the Serial comm. port is HostLink, 9600 Baud, 1,7,2,E but CX-Programmer by default uses Toolbus at 115200 Baud, 1,7,2,E. This conflict possibly caused the Sync/Async Communications in the Peripheral Service to take too long to execute and faulted the PLC. If anyone else has a better reason please chime in.
  19. Errors that appears when i connect via serial port

    Hmmm! What are your Serial Port settings? They should look something like attachment. Remember to "Transfer to PLC" AND MOST IMPORTANTLY POWER CYCLE THE PLC for the new settings to take effect AND set DIPSWITCH 5 to OFF.
  20. Errors that appears when i connect via serial port

    What is the pinout of the Serial Cable you are using? Looks like it may be incorrect and is shorting out the serial port and subsequently faulting the PLC.
  21. C200HW-MC402-E help

    I don't believe your CS1W-CPU44H is compatible with the C200HW-MC402-E motion card. At least that's what the manual indicates.     C200HW-MC402-E Compatible CPU's.pdf
  22. Will Sysmac Studio coexist with CX-One?

    If you are intending to use both CX-One and Sysmac Studio I would highly recommend installing them on the same VM. The Auto Update feature scans for presence of both applications and updates them both as needed. Very nice feature.
  23. UM Read Protection CS1 - how to remove

    Tasks and Function blocks can be individually password protected in the program whether ONLINE or OFFLINE. UM read protection locks out ONLINE access to the PLC program. You can use both.
  24. [Help]

    Interrupt Tasks will NOT work in simulation mode. Interrupts can ONLY be triggered by a physical input on the PLC.
  25. PWM 891

    NO. That's for setting up pulse outputs. For PWM it is NOT necessary to make any changes in the PLC settings. Simply configure the PWM instruction for the relevant output Port and desired frequency resolution [0.1 or 1.0 Hz]. Then use the Frequency and Duty Ratio to modify the PWM output pattern.   PWM Instruction.pdf
