plc 5/40e ethernet setup

[Racer Studios]

okay i have a plc 5/40e that is programmed from a scada running rs logix 5 ver(5.2.3) we programed the ip address for the plc with DH+ for channel 2.
We then hook up the ethernet cord to the 10 base t adaptor and try to find the processor on rs linx and it is unrecoginized... are we missing something?

we are thinking that the version or logix is to old for this processor that was new around 2002. Is this possible?

Well RSLinx is the one doing the recognizing. Upgradge them both. RSLinx and RSLogix).

[Racer Studios]

yeah but when i ping the ip i only get 50% and logix is doing the programming of the processor right?

Do you have a F series processor if so do you have Autonegotiate checked? Can you connect to yor switch and verify settings if your using 10 mpbs half and then check channel 2 in your channel config to see if they match up. perhaps.

If you unplug the ethernet cable going to the PLC and ping again what happens? perhaps a DHCP device has that IP already on your network?

unplugged the ethernet and pinged it and had 100%loss
so it is doing something.
not at works i am not sure what series it is...
but i know it has webserver capability and there is nothing even for that in our rslogix 5
we still thought it would be able to program its ip address

Dumb question but Did you add the IP address in RS linx under the configer driver for ethernet IP driver?
using a straight cable? Recycled the processor power after you changed the processor IP address.

Can you hook up a laptop to your connection and log on to your network to see if you have a problem with your network. Eliminate the PLC.

[Racer Studios]

the ip address was added to rs linx and it could not find it. it is a live process so it is hard to go down for this.
only had enough time to switch processor to program for a couple minutes to program the channel then we switch back to run remote.

An important question: Is the icon in RSLinx a yellow question mark or a yellow question mark with a red X on it ?

Just the question mark means that your RSLinx software doesn't recognize the version of the controller; this is very easily remedied using an electronic data sheet "EDS" file you can download from the Internet.

The question mark and red X indicates a timeout, which along with your 50% PING success makes me suspicious of the Ethernet port and/or the Ethernet subsystem on your PC or switches.

Since this is a 2002 controller, and it's supported by an old version of RSLogix 5, it's definitely not a Series F with a 10/100 Autonegotiate port. This port supports only 10 Mb/s Half Duplex Ethernet.

Does your switch indicate duplex with an LED ? Do you have a managed switch ?

Just to confirm, how did you program the ethernet IP address? Download the code via DH+? What is the IP address you used? What is the IP address of the PC?

[Racer Studios]

red x with question .
we already have 4 plc 5/40e processors that are alot older hooked up to ethernet and have been working for along time. it was very easy.
plug in the ip address. subnet. gateway. through DH+ into channel 2. then configured in linx it was not that hard. the port is working i used a laptop in the port and pinged it and it was 100%.
it has to be the way logix 5 is programming the newer processor right?..
logix 5 version 5.2? does not have webserver options and the processor has that which makes me think we need to update logix. thought maybe there was a trick someone might know on here to get past that.

Forget about RSLogix for the moment. The Ping failures are the problem you need to address. If Ping doesn't work then RSLinx won't work. If RSLinx doesn't work then RSLogix can't work.

Some Suggestions.



Use that same PC and verify that you can ping other devices
Try a different switch or a different port on the same switch
Try different cables
See if you can dig up an old hub even. An old hub will do 10Mb half-duplex.
Connect via DH+ and verify your PLC-5 ethernet port settings. Better still, get us a screen shot and post it here. Maybe do the same for your PC.

Verify these first and get Ping working before you even bother with RSLinx. Then once you get ping working, move into RSLinx.
