Why can't I get my Hardy 4050 to work with the EN2T/C Ethernet module?

I have a Hardy 4050 Controller, Firmware version 1.0.0.0.

We tried upgrading our ENBT module to an EN2T/C in our control logix rack and the scale would not communicate.  We put the ENBT module back in and the scale would communicate just fine.

Elsewhere in our plant we have replaced an ENBT module with and EN2T/B module without issue.  We have 2 Hardy weigh scales running the same HI4050 1.0.0.0 firmware talking to and EN2T/B without issue.

Have you had any issues with the Hardy 4050 Weigh Controller talking to and EN2T Series C??

Yes, we have found that if you are using an EN2T module with firmware level of 3.4 or higher, then our HI 4050 unit could have a problem with communications.  This issues was resolved with our firmware version 1.9.0.0.  
You should go to our web site page for HI 4050 controller and download the latest firmware for the HI 4050 unit.  This should then resolve all these issues.  Instructions for the updating of the unit are found on this page also.
