Enron Modbus

Where can I find the standard for Enron modbus? I am considering using it as a standard for gas measurement historical polls. I understand this is popular in the states. Is any one currently using it in Canada?
Thanks for your help.

I understand Mercury Instruments, a gas corrector manufacturer was going to support the Enron variant of Modbus. Per my understanding in talking with them a couple of years ago, Enron Modbus is Modbus ASCII and it supports function
codes 1, 3, 5, 6, 7, and 16.
