hello Im triying to conect two micrologix 1100 and panel view c600 with stratix 2000 ethernet switch, any idea about ethernet settings in two micrologix and panel view c600. Thanks

Well, yes. You need to give the MicroLogix controllers unique IP addresses that are on the same subnet as the unique address of the PanelView C600. Are you familiar with the basics of IP addressing ? Your question might mean you need to have IP addressing and Ethernet explained, or that you just have a specific question about the communications configuration in the C600 editor. Please post more details about your system and your question.

He got a few things in between the following sentence. This is the meat and potatoes of what we in the control world need to know so I am repeating it: "The Internet Assigned Numbers Authority (IANA) has reserved the following three address blocks of IP space for private Internet. These are not routable on the Internet. However, if used on an internal network these internal computers will be able to access Internet resources VIA mediating Gateways such as proxy servers" and the IP ranges are: "Reserved space: 10.0.0.0 to 10.255.255.255 172.16.0.0 to 172.31.255.255 192.168.0.0 to 192.168.255.255" The IT department of the company that I work for has set the (fairly common) range of 192.168.0.0 for our SCADA and control systems. Come to think of it I've seen 172.16.xxx.xxx in other locations so I can't say if I 100% know what they are doing. The IT department has subdivided that even further into catagories (PLC, HMI, Port Server, Cell Modem, etc) and that's what's important to me. We always use a Class C network so the subnet mask is 255.255.255.0 in every case. The default router address is always "dot 1", which means that the last octet for our systems is always 1. If you don't have a standard I would suggest that you work with your IT department to create one or do it yourself. Either way, have a standard scheme and document what device lives where. I use an Excel spreadsheet with a tab for each location to document addresses that I connect to. When I was a subcontractor I used the 10.10.0.0 (commonly referred to as 10 dot) subnet because I rarely knew what the ip schema of the location that I was work on was prior to arriving for checkout and startup. The 10 dot subnet fits into the "reserved space" area of the IANA so it's route able even if the customer did not put their hardware on a WAN. A lot of smaller companies do not have an IT department and have no defined schema. By using one of the three reserved ranges I gave them the flexibility to update their system without going thru an ip address change on their hardware. A good IT guy can create a route table and / or use port forwarding to accomplish the task of putting hardware on the WAN if it has a reserved address. Besides that it's easier to type 10.10.10.XXX Remember- I have the luxury of having defined ranges to work with. Here's a real world example of what I do when I add hardware to the network. BTW- bear in mind that my control network spans multiple states from Louisiana to Texas to Alaska but I was inside of a router so I could be confident that I wasn't going to overlap with locations outside of the router. I added a port server to the LAN at one of our facilities the other day. We use the following ranges for our SCADA and control systems. Note that this is for the last octet. The local area network (more specifically the router on the network) defines the other three octets: IP radios, EFMs .150-.199 PLCs .200-.215 DigiPorts/Serial Svrs .216-.229 HMI's .230-.249 ClearSCADA Local Servers .250-.254 I plugged my laptop into the switch and let the network assign an address to me using DHCP. It assigned 192.168.12.xxx. Since I was addressing a port server (aka Digiport/Serial Server. Digi is a brand. We also use Lantronix) I selected .216 as the last octet. The ip address that I selected was therefore 192.168.12.216 but we aren't going to stop there. We have to determine if there is another device on the local area network (LAN) that is using this ip address. Bear in mind that I was working INSIDE of a network defined by a router so I was on a LAN. The router(s) at the location that I was working live on a WAN or Wide Area Network. The router serves out the 192.168.12.xxx range of ip addresses via DHCP. I don't want my devices on DHCP so I hard code them to the range that I want them to live. I'm not the only person that works at the facility I was working in so it's very, very important that you know that nothing else is using the range that you select. You can determine this, somewhat, by issuing a ping command. Start >> Run>>> type CMD in the box and hit enter A black DOS box will pop up In my case I typed Ping 192.168.12.216 in the box and hit enter. The returned text was: Pinging 192.168.12.216 with 32 bytes of data: Request timed out. (this would have a time value in milliseconds if something that used the address above was on the network) Request timed out. Request timed out. Ping statistics for 192.168.12.165: Packets sent = 4, Recieved = 0, Lost = 4 (100% loss), This means that there are no devices currently on the LAN with that address or if there is one it's powered off or disconnected. If someone has a device that uses the address that I selected powered off or disconnected then the ping command won't find it. I knew that wasn't the case so I ip'd the device like so: IP Address: 192.168.12.216 Subnet Mask: 255.255.255.0 Default Router: 192.168.12.1 I always put a default router value in even if the network is closed and doesn't utilize a router. Here's a side note that may or may not be interesting. I have to use a lot of cell modems in the field for remote data collection. I use 192.168.xxx.216, xxx is the same number every time, for every port server I connect to a cell modem. I can get away this because we use the port forwarding capabilities of the cell modem to route the modems IP address to the hardware address. Our AT&T modems are set up on a VPN tunnel so they don't live on the public network We've been trying to make use of Verizon modems but for some reason our IT department can't set up the VPN tunnel. I'm not willing to hang any of my hardware on a public network and hope some wingnut doesn't stumble on to the control or SCADA system and knock it off line or worse cause damage so I haven't been able to take advantage of 4G yet. 3G has fairly high data transfer rates. Higher than some of the satellite systems that live in what I call the porn satellite area (low on the horizon, cheap, and nearly worthless for higher data sites) Private vs public networks. We don't have the only site in the cloud that uses 192.168.12.xxx so how is it that we can get away with using that ip range? Simple. Our WAN (wide area network) is connected to our LAN's (local area networks) via the "cloud" aka the internet backbone. There are a myriad of servers and routers (and probably other equipment that I'm not aware of) that serve out IP addresses and route traffic to all of the necessary points. Our LAN's live inside of our WAN. Hardware separates and connects our LAN's from the cloud. I am a visual person so I'm struggling with how to show you what that means with words. It would be easier if I could draw it on a white board. I'll have to stop there. Maybe someone else will pick this up and run with it. Edited by Michael Lloyd

Hello, Thanks for your answer. Yes, one side it is micrologix 1100 with ETHIP with IP (169.254.0.1) SUBNET MASK(255.255.0.0), the driver is configured in (BROWSE REMOTE SUBNET) option of RSLINK. The We have betwen two devices a Stratix 2000 Ethernet Unmanaged Switch, then We have (Panel View C600) touch screen, with IP(169.254.0.2) SUBNET(255.255.0.0), same setting to program device from LAN NET in my LAPTOP. On comm option, I have the addres of micrologix 1100 with same IP that ETHIP DRIVER of RSLINX. Some thing is wrong, because I didnt get with ETHERNET the proccesor from my laptop . Other question is about ETHERNET CABLE, is possible to use straight or is necesary crossed cable? Thanks for your fast answer, Marcos

I recommend you read up on ethernet addressing 169.254.x.y is reserved for automatic private addressing. meaning most devices won't route these addresses outside the adapter. Try switching to a 10.x.y.z ; 172.x.y.z. or 192.x.y.z network addresses and see if things work. I.E. -- Micrologix 172.168.30.1 ; Stratix Switch 172.168.30.3 ; Panelview 172.168.30.2 ; laptop 172.168.30.4 for example

Hello, Thanks, for your help . Now I am able to get the plc from my laptop by ethernet, but I have a problem trying to set the permanently IP ADRESS in channel 1 of processor. I did check BOOT ENABLE, write the IP, SUBNET MASK, and GATEWAY, then uncheck BOOT ENABLE OPTION, and appear the IP PERMANENTLY in PLC. Turn off the device and then I need to go again to BOOT-DCHP SERVER to assign the IP because is erased in PLC. Please let me know whats going wrong.

Care to share your hurdles and final solution? Other newbies might learn from and avoid your mistakes. Yes they'll make their own, but at least they'll be able to avoid the ones you made if the can read.

Yes, I did use the rslink server, and set the hardware number with temporally IP, then get the procesor with ethernet drive and set the IP. Following information about IP address. PANEL VIEW C600: 10.120.29.171 MICROLOGIX 1100: 10.120.29.170 LAPTOP: 10.120.29.172 All intgrated under ethernet switch. Thanks, Marcos Care to share your hurdles and final solution?
