ABB IndustrialIT Compact HMI 800 Getting Started page 38

Connection to Third Party Alarm & Event OPC Server
SourceName and ConditionName need to be configured according to the OPC
Specification. (In the OPC Specification it is stated: "A condition is a named state of
an OPC AE Server. Each condition is associated with an OPCSource. An
OPCSource may be a process tag or possibly a device or subsystem").
This example is done with the Compact Control Builder for AC 800M (PLC Control
Builder).
The AC 800M Connect can not be used in the 800xA System if the OPC Server for
AC 800M is to be used for alarm handling as described here. This limitation is only
valid to the OPC Server for AC 800M and not for third party OPC Servers.
In this example three alarms are defined and used so they will be displayed on one
Object in the Compact HMI 800.
The FB AlarmCond is used in this example. The SrcName is set to
MyObjectName_A and the CondNames to SignalName_x. Note that the
SourceName must be unique!
