Controllogix native tag support to HMI (Red Lion)

So I was unsuccessful with my previous attempt with...

So I am coming at a different angle with native tag support…

I was successful in connecting the two devices together, but now it appears that the Red Lion is not receiving data from the Controllogix. Again I followed the instructions – I exported/imported the data tags. I didn’t manually try to add the tags.

HALP!

is the processor receiving data from the red lion?
what errors are there?
yellow triangle's in logix?
if so what 16# error?

Thanks for the reply.

jde777 - is the processor receiving data from the red lion?

I do not know. The three "trouble lights" on the EthernetIP module are glowing green "LINK, NET, and OK" and the IP address of the module scrolls across the 4-charater display. So I believe that the EthernetIP module is happy.

jde777 - what errors are there?

No errors per se, but it appears that there is no "tag" data being sent to the Red Lion HMI. The tags that I imported into the HMI are present in the programming part, but when I display the value of the tags onto the HMI screen, I only get "-----" for the valve of the tag, which I believe is no data.

jde777 - yellow triangle's in logix?

No, everything appears to be happy in the PLC. A simple ladder logic program verifies that inputs and outputs are working on the PLC side.

jde777 - if so what 16# error?

I do not understand this question.

So, it sound like the enbt is configured with an ip address and communicating.
16# error are what you would see in rslogix 5000 if a module had a yellow triangle next to it. You could see what error by right clicking on the module go to properties and on the connection tab would display the error.

are all of the tags you are using "Controller Scoped"?
have you selected the Allen Bradley Native Tag Addressing driver

does the red lion have any leds to indicate status?
the tags you are trying to display, what data type are they? bool/real???

Thanks for explaining 16# tags.

Yes all of the tags are controller scoped. There are NO tags that are program scoped.

I followed the directions in the technical notes where I was to select the ethernet protocol type - Allen Bradley Native Tag Addressing

The Red Lion has three LEDs in front of the panel, none of which are in error or can indicate Ethernet communication. In back of the Red Lion located at the Ethernet RJ-45 plug there are two communication lights which signal that the Red Lion is communicating on the Ethernet.

There are four tags which I exported from the Controllogix, two INT (16 bit) and two BOOL (1 bit). The Red Lion imports these tags into the correct format.

*** A side note, I am using a 1756 - 5555 processor, not the 1769-L32E as stated in the technical notes.
