Overview

1.9.1 Transmitting Error Reporting into OPC Alarms and Events error data

The conversion of Error Reporting messages to OPC Alarms and Events

error conditions involves the C-Bus network, C-Gate, OPC Server, and the

OPC Client as shown in the graphic below. The C-Bus OPC Server passes

Error Reporting messages retrieved from the C-Bus network to the C-Bus

OPC Server. The C-Bus OPC Server houses the OPC Alarms and Events

state machine which manages the error condition states of all Error

Reporting ready C-Bus units.

type. Each table cross references the OPC error conditions against the

Error Reporting messages stored in C-Gate:
