RSLogix 5000 / Hach

[Chris_M]

Usually I go to Hach with these problems but they are being slow to respond and sending me Italian emails...?


RSLogix 5000 - 1769 L32E PLC
Trying to communicate with a

Hach SC4500 controller over ethernet.
I set up the .eds file and configured the controller IP address, module revision etc.

I can ping the controller fine but I cannot connect in RSLogix.
There are no error codes the lower corner of the module properties reads Status:Connecting...Status:Faulted...


Any help is appreciated.

Can you see something like this ??

Have you downloaded manual at :

[Chris_M]

I have read through the manuals, they seem to assume that the connection will work.



The Connection Faulted status reads 1

Is your hach unit IP address compatible with your PLC address. ?

 

[Chris_M]

Yes XXX.XXX.XXX.71 and XXX.XXX.XXX.75

 

[Robb B]

Yes XXX.XXX.XXX.71 and XXX.XXX.XXX.75

Same subnet mask? It's caught me before...

 

[widelto]

My only observation is that all the examples are done in Studio 5000, that means that is greater than V21 and your PLC L32E goes up to V20.

 

[Chris_M]

Same subnet mask.
Just tried adding the controller to a Logix Designer (V32) Project on a L16ER. I'm getting the same error and same Connection Faulted Results (1)

Did you follow the user manual?

Make sure that the Ethernet port configuration in the controller is set to one of the IEP (industrial
Ethernet ports) options.
1. Push the main menu icon, then select Controller > Connectivity > LAN > Ethernet ports.
2. Select one of the options that follow based on the wiring configuration of the controller.
Option Description
IEP only The two Ethernet ports are configured for PROFINET or EtherNet/IP. Port 2 in the
module is enabled. Refer to Figure 6 on page 7.
MIX IEP One Ethernet port is configured for LAN connectivity and the other Ethernet port is
configured for PROFINET or EtherNet/IP. Port 2 in the module is disabled. Refer to
Figure 5 on page 6.
Note: When Mix IEP is selected, LAN port configuration shows in the LAN menu. LAN port
configuration setting is used only for LAN connectivity configuration, not for Industrial Ethernet
port configuration.

By default it wont work as an Ethernet/IP interface, and only port 2 is enabled.

Well I am not sure exactly were I went wrong. Somehow I got the EthernetIp and LAN ports confused and plugged into the wrong one.

Seems to be working now. Thanks for the advice everyone.
