How to connect to Honeywell PHD?
Install the PHD client tools on the Plant Integration server.
Copy the PHDAPINET.dll that is part of the Client tools installation to the Plant Integrations bin folder. The default location would be: C:\inetpub\PlantIntegrations\bin
The TrendMiner connector (plant integrations server) by default uses port 3100 and 3150 to connect to the PHD server. Make sure these ports are not blocked by a firewall and the connector can connect to these ports.
