So, given that many plants are hybrids, are you saying that this document applies only to the process control parts of the plant? Or that hybrid plants are also out of scope? If there are scope constraints, what exactly are they? What happens in a hydrid plant might be significantly more complicated, as it involves two kinds of networks; if there is a desire to have the different pieces interconnected. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
