I'm working on Allen Bradley Control Logix redundant PLC's.
This is the setup of my PLC's.
I have a 2 redundant PLC's, one stand alone PLC.Each of them have their own Control Net network.We are using an Intel SE7501WV2 server with Windows XP(Professional).Allen Bradley does not have a Control Net Scanner for this server hence I am using Ethernet to see the Control Net.So the two PLC's have two different ControlNet networks, and so I have two different Ethernet's for both the ControlNets.This layout should explain my situation.
Workstation
----AB_ETH-1 Ethernet
-129.57.42.118
-Backplane
+ 0 CNBD
rest of the modules
----AB_ETH-2 Ethernet
? 129.57.41.139 Unrecognized Device
I have a server and three different client PC's.
In my Rslinx in the server and two PC's I can see the EtherNet network 2( i.e AB_ETH-2)i.e does not give me an error (unrecognized device).
One of the client PC's is a laptop.
This is the configuration of the PC's
RSLinx Windows Ethernet
Server 2.42 XP Prof Recognizes
Client 1 2.41 XP Prof Unrecognized
Client 2 2.42 Win 2000 Recognizes
Client 3 2.42 Win 2000 Unrecognized
(Client 3-Laptop)
There are two cases which can cause this.
1.The EDS files for the modules are not installed.
*RSlinx recognizes one of the Ethernet module which means that the EDS files are installed.
2.There is no module with the IP configuration
* The same Ethernet module is being recognized by another machine just not this one.
I can ping the Ethernet Module from both the machines which do not recognize it in RSlinx and that works fine.I have tried to uninstall and install linx and it does not work.I have checked for firewalls( Allen Bradley suggestion) but nothing there.Am I missing something here?
