  1. The problem I am having is costs. The OEM of the machine has the program locked. There is only 4 devices on each machine. 2 i/o modules an HMI and a PLC. They are all small machines but we have no plans of having that machine being able to initiate communications out. I just want to read maybe 10 tags out of the machine. It's not worth the 2500 dollars per machine they want for the programs. That's 10 grand and it's just not worth it for what we are trying to accomplish. Likewise it would costs around the same to have the OEM come out and change the IP addresses. I am not sure what you mean by creating a VLAN on each machine. Currently the NAT device I found is around 260 dollars. If I could do it cheaper that would be even better. Also I do not have the hassles of dealing with any corporate or local IT department. They do not want anything to do with the PLC network and all communications are done through a single machine with 2 network cards. Currently I am the only one making any changes to the PLC network. And I keep a record of all of the devices and IP and MAC addresses. I also label them locally at the device.
  2. Opc. I am going to use the driver in Ignition to browse the tags.
  3. Unfortunately the switch I have does not have this feature. I just checked the product ID. I will check tomorrow first thing with out local AB rep to see if this is indeed an add on functionality that I can purchase. But I am still thinking I could probably do what you suggested and find a router that supports 1:1 NAT. I am learning a lot through this conversation and I greatly appreciate your help. Each machine does have it's own LAN. We have all of the ports on the stratix switch setup as one big VLAN. Basically just using it as an unmanaged switch. But it looks like I may not be able to utilize that switch. Unless there is some way to use port forwarding. But I would probably still have issues with the machines trying to communicate to one another since they all have that exact same VLAN setup. If you have any suggestions on particular NAT 1:1 small router let me know. If I can configure 5 cheap ones real quick then I wont even fool with the Stratix switch.

  5. Could this be what you are talking about? It says that stratix 5700 is capable of creating a NAT.
  6. The drawing is exactly what I am trying to do. I'm not sure what a NAT device is, I will have to research that.And I am trying to pole them to read the tags that are in them. They are in a temperature controlled area that rarely goes above or below 70 degrees Fahrenheit so the residential equipment will be probably be fine. I do have a managed switch they all connect too. So just to make sure I understand what your saying. I need to get a NAT device. Which I will figure out what device that does. It sounds really straightforward the way you explained it. Basically this device will take the IP of the PLC and forward it to a different IP that I can use on the PLC network to communicate and pole its tags? Networking is somewhat new to me. Other than putting everything on the same network I haven't done much with port forwarding or any type of complex communication paths. Thank you so much for your response.
  7. Ok guys, this is more a networking question involving a Stratix 5700 managed switch and 5 machines. The five machines all have set IP addresses from the OEM that cannot be changed. The manufacturer has them set in the program to maintain that IP ,so if it sees the IP change it will change it back. With that being said all Five machines have the exact same IP configuration and I cannot change it without contacting the manufacturer and getting them to change it or sell me the program so i can change it. both options will costs entirely too much in my opinion. With that being said my only goal is to read tags from the PLC on each machine. Is there anyway to set each port on that Stratix switch where i can communicate with each  machine individually without causing them to have IP address conflicts with the other machines that have the same IP address. I hope I explained my question well enough. Thank you in advance for any help on this issue.
  8. I have multiple PVP 1500's on the same network. From the one in my control room i need to be able to see what user is logged into what HMI. How would I address the system tag of another HMI on the same network would I use the IP address? thank you for any help in advance
  9. Newly added tags won't show up in ME

    Thank you Joe. I will definitely keep that in mind.
  10. Newly added tags won't show up in ME

    I apologize for posting twice about the same thing. I thought I had done the first one wrong. I have never used a public forum before. I did find the solution. When I had move studio 5000/rslogix to the new computer the default tag scope was set to just that program instead of the entire controller. That's why the new tags wouldn' show up. I just created new tags with the scope of the controller.
  11. Newly added tags won't show up in ME

    This happens after I download to the HMI panel. It says route unresolved or something  
  12. I downloaded it to the Parkview 1500. All of my edits in the L72 were done online so I know the tags are valid. Every  tag from that processor is working except for the ones I just added.
  13. Any new tags I add in studio 5000 the HMI project shortcut cannot locate the tags, it says unresolved route to processor. It's the same shortcut all of the other tags are using. Please help. 
  14. This is my first time to the forum and I am still very new to plc programming. I just had to move all of our software over to a new computer ( kind of new) it's running windows 7 pro. The same is as the computer before. Same computer name, same I'm, same file directory. However when I add tags in studio 5000 and reference them in the HMI, it says it is unresolved in route to the processor. It only does this for the new tags. I used the same shortcut and everything so I am at a complete loss here. What do I do.
