  1. Delay transfer signal between 2 controller logix

    Thanks BobLfoot, We have 2 controlnets.  The first net is PLC1-Cnet(Node3)  -  Cnet(Node 50)-PLC2: This communication worked properly even PLC1 and PLC2 incompatable version and do not need to schedule PLC2 in PLC1 network. The second net is PLC1-Cnet(Node4)-Cnet (Node14)-Cnet(Node16) -  Cnet(Node45)-PLC3: This communication have problem as I mention above. Actually when I remove Cnet(Node45) to disconnect with PLC3, I found the controlnet led A,B sometime blinking (It mean communication drop this time). When I remove Cnet(Node16,NOde45),  PLC1-Cnet(node4)-Cnet(node14) led A,B not blinking. So I guess we have problem from Node14 to Node 16.  From Node 14 to Node 16 is 2km and We use repeater 1786 RPFM and fiber optic is Multimode. Normally, multimode fiber just design for short distance.  Have you think multimode fiber is problem? Thank you very much
  2. Hello. I have main PLC L73 with redundancy module, and 4 others controller as L71, L72 (S/R A,B, CSU A/B). They connected through control net network as my attached document. I created message to read and write DINT, Real in main PLC L73 to others controller. I can read and write signal but sometime I have delay 20s to receive signal. Has anybody know my issue? How can I fix it? Thanks you Coal handling configuration.pdf
  3. Delay transfer signal between 2 controller logix

    Thanks Bob. Because our system have builded from others suppliers and they use different software version. As you talk we need upgrade Studio, RSNetwors for all to same version? It really inconvenient. I don’t understand what they mean: unschedule message and producer/ consumer schedule.
  4. Delay transfer signal between 2 controller logix

    Hi Bob. It show all others CPU, and cnet identity mismatch in RSnetworx but Module indicate OK . Because other PLC and cnet use different version. PLC1, Cnet1-  Cnet2, PLC2. I guess problem is PLC1 and PLC2 Both PLC configure Cnet2 and PLC in different version. So I think Cnet2 should be not scheduled both side, then can send message to transfer signal.  Thank you for your reply
  5. Delay transfer signal between 2 controller logix

    Thanks Bob. Yes, I found others controller and local controlnet module from other users identity mismatch. Before I used producer/ consumer tag to transfer, But controller mismatch. Thats why I use unschedule message. So I hope this fault not affect to this issue I am worried to reschedule network now. 
  6. Delay transfer signal between 2 controller logix

    Thanks BobLfoot. I tried to use read messages in all controller, but it is same issue. It look like communication drop each 20-25s and reconnect. I don’t have experience with control net. So I don’t know, maybe something wrong in this network configuration. 
  7. Delay transfer signal between 2 controller logix

    Thank you for your reply. However our controller L71,L72, L73 are in different version. When I tried to use producer/ consumer tag, I get an error “ controller not match”. Thats why I created  message to read/ write. I created message write/ read from L73 to L71 and from L72 to L73, I still got same issue, is sometime delay 20-30s to receive signal. I will try to use only read messages in all controllers and see what happen.
  8. Hi everybody.  I want to connect my laptop to module MVI56 MNETR and upload setting then change some information. Module IP: 192.168.1.12.

  13. Rslogic 5000 v20.01 Security

    Dear all;   I want to authorize users on a computer. For example, only the Engineering account can use Rslogic5000 to download the program to the PLC, Others acc is only operate on factory talk view but can't use Rslogic 5000 to download. I read in Factory talk security document. There is Windows-linked user accounts but I don't know how to apply it to this situation. Please guide me. We use Rslogic 5000 version 20.01.
  14. SIMPLE SCADA

      Dear Andy hill. I have small system with compactlogix to supervise 4 analog and 4 digital(start,stop). I tried to use Winlog SCADA. The first, I use WINLOG LITE, but i can't connect to rslinx opc server. I configured in RSlinx DDE/OPC Topic configuration and config in Winlog (OPC Client: Server node: my PC; OPC server: Rslinx OPC server and tried to create sample template; But i can't connect to data. Please giude me hot to do. Thank you so much

  16. PLC hardware

    Please help me to establish PLC system with best solution for my problem. I want to make SCADA have 1 PC to supervise 4 input analog is: FLOW, PH, Temperature, Total, Clo. Request to use Allen bradley PLC. and my system will communicate to YOKOGAWA DCS by modbus. So help me to choose allen bradley plc module is available for my system. I will use winlog pro 33.2 SCADA because price is better than Rockwell automation. Thanks.
  17. PLC hardware

    Thanks for your reply. I have a question. I want to lock controller logic to prevent other people download program. How can I do? I already read about Logix security tool. But in my understand, this is only prevent to upload and edit program but still can download new program to PLC. 
  18. Hello all. i have a question.  If you install security for CPU, this is only prevent upload and edit program. However others still can download new program to PLC. Can you help me to understand clearly.
  19. Winlog (Pro or Lite) with AB SLC500 series

    Hello, This is the first time, I use Winlog Pro to make SCADA. I have small PLC system with AB/ micrologix 1100. Who can help me to connect Winlog Pro and Rslogix5000. Thanks.

    Thanks Mr.kaiser. OK, I see CompactLogix_5370 is available for my application. But I have 1 PC( SCADA) to supervise 4 analog and we can see history. So how can communicate from PLC to SCADA. Maybe we need more ethernet module? And I think we need send signal to Yokogawa DCS by Modbus RTU.
