Thanks, Joel.
The thing is that power plants usually support Modbus only, and customers want to see them with their monitoring solutions (usually SNMP-based).
We have been playing around with MangoES and it solves the sending email alerts part of the solution, but not the other one. We currently provide other gateways, but I guess MangoES could be a better choice, since it could both generate emails and do the SNMP thing, eventually.
Modbus and BacNET publishers look great, btw, but only with our monitoring systems..
