    Thank you guys! I have searched and searched I don’t know how I haven’t seen the above thread. This should be simple enough . By the way Michael I have setup 13 remote sites and all working fantastic thanks to your help previously . I just wanna add some protection Incase something goes down at a pump station .

    I have remote sites with micro 820s and a controllogix at plant.. I need to set up a simple heartbeat or something to make sure communication is Okay. Currently I have been using the msg .DN and .ER to flag if something is wrong but they want a heart beat to write  a number , read a number and then compare if it’s not changing . I set up a timer and a counter for the heartbeat on the clx . Writing and reading from the 820.  but I’m having brain freeze on the logic to be able to compare to see if the number read is the same for more than let’s say 10 minutes . (Messages are being sent every 1 minute)

    Sorry sir I have been busy ! The only thing I have done successfully is the message between the controllogix and micro 820. But I assume it should be the same . Path is crucial . What kind of error does it give you? I’m no pro but Michael put me through the ringer and helped me accomplish so much! Great to have people willing to help.

    So it doesn’t matter to read or write all the “tags” ?Example I have a udt setup called Sophia_booster with

    pump auto -bool

    pump hand -bool

    Discharge psi -real 

    flow gpm -real 

     

    I only want to write the pump auto and pump hand bool’s from the controllogix because the other values Im reading from the other processor’s analog inputs  so what happens if I send the message ?

    Okay so here’s the latest I figuered I would keep this in this thread Incase anyone else in a similar situation. 
    Another remote site a booster station 

    will have 4 analog values to read 

    couple relay inputs and relay outputs for pump control. 
    again a micro 820 

    is there a way to get the data packed into one message ? What’s the best way. I know this is basic but you have been a ton of help to me!! . We will just control off of time example- pump run 6am to 6pm . Very basic setup

    We have a enclosure we want to add a hmi screen to just to see some important things in that area of the water treatment plant ( specifically the filter gallery) . What options are out there that integrates easily with studio 5000/controllogix platform and are robust. Something around a 10” screen . Thanks

    Okay so I connected my 820 in the ethernet card the cell modem normally connects to.. and had to change the tag in the 820 to a “globally defined “ tag . And it works, I adjust my generator and the value goes up and down as it should in the controllogix .. when I try to go through the cell modems ... nothing . Still feels nice to get that far though. Any suggestions? Thanks for the patience!

    thank you very much sir . I shall report back after tomorrow .I felt accomplished just getting ccw downloaded and connected . it’s way different than studio 5000 I hate it . But I’m going to do all the scaling in the controllogix and just get the raw value from the 820 . So I have like one rung of logic on the 820 and that’s just a “any to real”  to name it “upper_glade_raw” . Sound right ? Seemed to simple lol I hooked up a 0-10v generator and it my values changed (0-4095) but it just seemed like that was way to easy.

    I have never been interest in learning networking but I guess now I should probably learn the terminology. Ugh! Thank you for the replies and taking time to help me. There’s a lot of info out there but having someone hear your situation puts my mind at ease that I’m trying to learn the right thing to do for my application. I guess for now I could just hook up a Ethernet cord from the controllogix to micro to play around with this ? I even have some transducers I could hook up temporarily I just need a resistor .

    Thanks for the replies ! I actually got it to Work after much frustration.. it had to do the gateway setting on the en2t and “device ip “ on the modems . They had to be set the same . It automatically popped up the micrologix into the tree after that ! We are getting everything switched to Verizon’s apn so it’s secure so that’s all the testing I’m doing right now considering it’s all gunna have to change cause right now we Have public static ip addresses... but in the mean time ... any advice on the logic? I’m guessing message instruction from the controllogix to the micro820? What about polling to minimize data useage? Keep in mind there will be 13 remote sites right now with expansion as we can for other things like pump stations. But for now it’s just gunna be water tank sites with a single 4-20ma transducer . Thanks again!! Lay it out basic cause I know enough to be dangerous but want to learn the right way to do things !

    We already have the hardware we just can’t get it to mesh.. 

    for instance 

    the en2t port configuration settings ? The card is 192.168.1.55

    the modem static ip is 63.40.219.224

    portstart 44818 portstop 44818 host ip 192.168.1.50 port stop 44818

    the micrologix for testing is 192.168.1.100

    the modem static ip is 63.40.219.222

    portstart 44818 port stop 44818 host ip 192.168.1.100 port start 44818

    it will not show up in rslinx under the en2t card

    hello new here, first of all im no pro and a big noob but need some help if willing. I work at water treatment plant with a controllogix rack, we have 13 tank sites that we are trying to communicate to through sierra wireless rv50  cell modem with micro 820 controllers, most sites will just have pressure transducers for tank level. locally we cannot get any help setting this up. we have a modem for the plant connected to a en2t card in the controllogix chassis. we are setup through verizon have have static ip addresses . can someone please help walk me through getting this going. Thanks
