I have never seen the GE Fanuc Ethernet specifications in an online manual. However, they call it GE SRTP and it is very similar to SNP packets over ethernet. You can get a good feel for what the PLC is expecting and how it reacts by reading GFK-1541, which is available from GE Fanuc's web site. http://globalcare.gefanuc.com/ You will be better served by purchasing the Developers Tool kit by contacting your local GE Fanuc dealer, or there are several people who sell OCX and OPC kits that range from $0-$1000. GE Fanuc is happy to sell the specs, to even competitors as this also promotes GE Fanuc PLC usage.

thanks for the information. I also found some minor details from GFK-2296 and GFK-2382.
