    I tried with a dummy program,with just one rung,2 B3 bits being used.downloaded to both L432E & L533E,took a fresh SCADA.

    Configured Rslinx Enterprise with both processors and different shortcut names.

    when i searched for online tags in tag data base,data table address of L532E was there,and nothing from L533E.

    I tried the same with one processor at a time.

    what i can see was Rslinx Enterprise was not able serve for L533E.Nothing comes from or goes to Rslinx Enterprise.

    Either something is prohibitting Rslinx Enterprise to communicate with L533E or it's not compatible.

    Feeling so..

     

    I want to add one more thing.

    As i said before,this is a migration project from Rsview32 to Factory talk view.

    Both of these types plcs L532E & L533E worked well with RSView32.

    Yes, that is definitely possible.    FactoryTalk View's diagnostic log will generally indicate the data table addresses it cannot read or write.

    Thankyou sir for your response.

    I checked with serial port configuration of both plcs and found as same.

    By difference in data table address,did you mean like Iam having an address in SCADA which is either beyond data table elements or not used in data table?

    The Net-ENI can handle up to six incoming TCP connections.    It's possible that if you are connecting to it with too many computers, you have overloaded it.

    I don't think the Web interface allows you to see the number of TCP connections;  I don't have a Net-ENI Series D to test on.    I do know that you can connect via Telnet to the device and send some commands to get some status data.

    Here's a Rockwell Knowlegebase article about how to do that (TechConnect required):  KB 27418.

    One common issue is that an RSLinx Classic station with an RSWho browse open will create and maintain a connection to a Net-ENI, so it's possible that in a large enterprise network that you have computers that are just running RSLinx in a background window that are taking up resources on the Net-ENI.

    Sorry for late reply sir, 

    I tried with 1 PC and 1 L533E Plc via 1761Net Eni,Opened Rslinx Enterprise, Added Ethernet driver manually,configured L533E plc IP.

    I was able to see my plc.

    But when i browsed for online tag addresses, nothing was there.

    Also when i made a screen test, nothing was updating in screen.

    When i tried the same with L532E processor, everything was fine.

    So now the net eni is connected to 1Pc & 1 PLC ,still the issue persist.

    There is no difference between the 16K and 32K controllers in their ability to communicate via the serial port.

    So your problem could be in the configuration of the serial port, or with physical damage to the serial port, or with differences in the data table addresses that you are attempting to read and write.

     

    But it's not a firmware problem.

    Ah, I see. I misread your reply too. I guess it also depends on why he reduced the update rate in the first place. To save network traffic or to just slow down how often the numbers change on the display? If it's just to reduce how often they change on the display, he could buffer them in the PLC, but if he wants to reduce network traffic, that won't help.i

    Reason is the latter one sir,I want to slow down how often values are updating.

    Could you not just update your motor speed every 1 second from the PLC Tag then keep your HMI settings the same as before?

    Thanks for your response sir.

    How can i set plc tag updation rate in Factory talk view, sir?

    In Ftview I have seen screen updation rate only.no option in tag configuration window i think.

    This was possible with RSView32.I have seen an option to set scan class for each tag there.

    Helo All,

    Thanks for your support on my previous quiry.

    Iam now facing an issue with rotation animation of a motor in factory talk view.

    I have a screen containing 5 motors and good number of numerical displays.

    Numerical displays need to be updated just every seconds ,so i changed screen updation rate in SCADA as 1,

    changing so decreased my motor rotation speed.

    so do i have any other option to change motor animation fast keeping numerical display screen updation rate as 1 second??

    i have used the tag  syste/blinkfast

    Thanks for responding..so the details are like..

    1)Iam using two processors 

    1.SLC 5/03 L432E OS302FRN 10 &later which is having 16k memory

    2.SLC 5/03 L533E OS302 FRN 10 & later which is having 32k memory

    2)Catalog number:1747 L532 & 1747 L533

    3)Iam using Ethernet protocol

    4) currently it is running like RSView32 in pc1 & ftview in pc2 seeing same above processors.

    Even when Pc1 is turned off and using only Factory talk view,I can see both plcs in Factory talk linx,but online tags and graphics are available only for L532 processor.

    Hi sir,

    Iam facing an issue somewhat similar to what you got above.I was using Factory talk view 10.0,communicating with slc 5/03 processors via factory talk linx.

    Issue was like,only 16kL532) processor was showing online tags n data  getting into SCADA,for 32k processor (L533),i was able to see the plc node,but nothing coming to SCADA.I tried adding plcs manually n nothing happened.

    don't know what iam missing out.

    plz help me..

    Hi all,

    Iam currently working with a migration project from Rsview32 to FTView.

    I was able to convert the RSView32 SCADA to FTView successfully.

    Current scenario is like RSView32 (which was the existing pcs) SCADA is running in two stand alone PCs and Iam trying to line up the new Factory talk view SCADA in another system.Communication is taken from same ethernet switch to which all ethernet cables from 5PLCs in the field are terminated and from which RSView32 scada has taken itz communication.

    PLCs used there are 2 No.of  1747 L532E slc 5/03 OS302 Ser c Frn 10 & later and 3 Nos of 1747 L533E slc 5/03 OS302 aer c Frn 10 & later. communication taken via net eni (1761 NetEni) Ftview installed system is Windows 10 pro OS)

    Issue is while RSView32 scada is working properly, Factory talk view is not getting neither online tags nor able to play display for those linked with L533E processor.But everything is fine with L532E processor.

    I just tried with downloading L533E program to L532E processor and everything was getting.

    So am i missing something or what should i do to get proper communication with L533E processor.

     

    plz help..Iam a beginner in this field.
