good idea, some OPC client applications may have a limited display window when browsing the tag space of an
OPC server. The phonebook tag name is part of the OPC browse data. Phonebook tag names must be unique
within a given device.
 The Number parameter is used to enter the phone number that will be dialed when the tag is invoked from an
OPC client application. A string of up to 64 digits can be entered.
 The Description parameter is used to attach a comment to this tag. A string of up to 64 characters can be
entered.
Note: With the server's online full-time operation, these parameters can be changed at any time. Changes made to Tag
Properties will take effect immediately; however, OPC clients that have already connected to this tag will not be
affected until they release and reacquire this tag. To prevent operators from changing these parameters use the User
Manager to restrict access rights to server features.
Built-In Diagnostics
Communications problems may occur upon occasion that require insight to their cause. In these situations, an advanced
user can employ the various Diagnostics views available to help determine what the communications problem may be.
Two diagnostic tools available in the server are the
OPC Diagnostics Window and Channel Diagnostics . These
views provide both server and driver level Diagnostics for advanced users.
OPC Diagnostic Window
The OPC Diagnostics Window provides a real-time and historical view of OPC events that occur between any OPC client
and the server. An event is a method call that a client makes into the server, or a callback the server makes into a
client. This window is separate from the main server configuration window, which can be used to hide the window even
while diagnostics are being captured. In the event that there is an issue between a client and the server, the
Diagnostics Window can be opened to display the events that have occurred. The operation of this view can be
controlled through the menu, toolbar or by right-clicking in the Event Window.
The events and details captured by this utility are specific to the OPC Data Access 1.0, 2.0 and 3.0 Custom
Specifications. To determine the meaning of the data presented by this window, refer to those specifications. Copies of
these specifications can be found on the OPC Foundation web site: www.opcfoundation.org.
