1.1 Introduction
The Smart Wireless Gateway enables IEC62591 WirelessHART technology; wireless transmitters
communicating with each other and the Gateway in a self-organizing wireless mesh network. The
Gateway manages the network, its communication, security and connectivity. The gateway is the
entry point for wireless device data that is then converted to a format that is compatible with other
systems. In the case of steam trap monitoring this other system is SteamLogic, monitoring software.
This document focuses on OPC system integration for the SteamLogic software and the Rosemount
708 Wireless Discrete Transmitter.
The objective of the SteamLogic OPC Server is to give access to the trap state that is calculated
within the SteamLogic software.
1.2 OPC mapping
The following table translates the OPC value, seen by the client, to a steam trap state and user
interface icon.

Meaning
0 Good Steam trap is functioning normally under the current settings
1 Cold
Steam trap is in a failed cold position. This steam trap may have a mechanical
failure or could be plugged with solids. It could also be flooding or
undersized for the application making it unable to remove enough
condensate. Otherwise the steam supply could be turned off.
