    Thanks for your reach reply. I checked quick compare online/offline project and found: The project languages are different: Editting language: en-US Downloaded logic to PLC: zh-CN. 
    So how can I change editing language to zh-CN. Need reinstalled software and select China language?

    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

    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.

    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

    Looking for links to some simple SCADA What I need is a Scada Package or HMI package or some sort of OPC visualization to allow maybe max of 100 Points this needs to be ideally Freeware. or very cheap ware. Need to be able to communicate with OPC Server or Allen Bradley Controlllogix THis will only e used to display some PLC data for inhouse testing. I did try WINLOG LITE but it times out after about 10 mins - other wise it would have been perfect. We have full blown Wonderware for the main systems. but this means installing wonderware and servers etc I'm looking for something simple just to develop a few simple test tools graphics will be simple a few button and lights with some analog values. No need for security etc. ideally easy to set up on different machines in about 10 mins

    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

    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.

    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.

    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.

    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.
