  1. Thanks for quick response and app. note. Connection via Serial as gtsupport mentions works just fine. But I really prefer to go with Ethernet if I can get it working. Attached are extracted pages from IDEC manual showing that the HMI "should" be capable of connecting directly to the PLC. Setup procedure in IDEC WindOI-NV4 is somewhat confusing and missing anything regarding the need to use CX-Integrator as IO_Rack mentions. Have contacted IDEC Tech. Support and await reply. Meanwhile I'll continue working with "Good Ole Serial" Idec Specs 2.pdf Idec Specs 1.pdf Idec Specs.pdf
  2. I am struggling to establish Ethernet communications between an IDEC HMI and OMRON PLC. Can ping both devices on the network, BUT HMI shows a communication error "ID:00h 0". Anyone have any suggestions how to resolve? Do I need to use CX-Configurator to setup a routing table, and if YES how to do it?   Frustrated/Confused.
  3. CP1L and timers in ST

    So how about showing us all how you did it? Sharing feedback on posts is one way of showing gratitude and helping other MRPLC members who may have similar problems.

    ST TIMER not supported on CP1L http://forums.mrplc.com/index.php?/topic/28706-timer-in-function-block-with-cp1l-e/#comment-136695
  5. Ethernet/IP to Profinet IO with CompactLogix 1769-L18ER-BB1B

    Feedback after project completion. The combination of a CompactLogix 1769-L18ER-BB1B and ProSoft PLX82-EIP-PNC worked like a charm. Pretty straightforward to setup and after writing an AOI allowed quick and simple connection and control of multiple Profinet devices. Only gotcha was figuring out that BYTE swapping was required on both input and output maps. The PROSOFT gateway allowed this change to be easily implemented vs. writing additional code in PLC. Couldn't be happier with the results!!  
  6. Produced/Consumed Tag Communications Active

    Thanks Ken, some of the tags in the producing PLC are AOI's. I don't currently have access to the test whether AOI's be included as a member of a UDT and successfully passed to the consuming PLC. Any suggestions/feedback most welcome!
  7. Produced/Consumed Tag Communications Active

    AHA!! Looks like Mr. Ken answered this already!!  
  8. Produced/Consumed Tag Communications Active

    OK I reviewed the Ptoduced/Consumed manual so will set Connection Status Included for the tags [see picture], also found this on the Rockwell CustHelp site. If RSLogix 5000 version 16 or lower is being used, this exact method is not possible.  Several options would include using the GSV with the CONTROLLERDEVICE object, Status Attribute, or use the MODULE Object with the EntryStatus Attribute. So AndrewG's method will work, but I am using V30 and would like to implement the UDT approach. What is not clear is how the UDT is structured. If I understand correctly the UDT requires just a single member of type CONNECTION_STATUS. Can anyone confirm if this is the correct approach? Again many thanks to all for feedback.
  9. Produced/Consumed Tag Communications Active

    Thanks Ken but I cannot access 60813 because it is only available with a Tech Connect subscription.  
  10. 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!!
  11. 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.
  12. 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!
  13. 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?  
  14. 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.
  15. 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
