Tag Name: these fields should contain the tags you want to share with the server. If the tag is an
array or a class (or both), every element and member is shared. You should only put the tag name
in this field, without specifying the index or class member. If you specify an index or a class, the
TCP/IP Client module will ignore it.
Remote Tag: these fields should contain the name of the tag that will be linked with the tag
specified in the field Tag Name. This field is optional. If you leave it in blank, the same tag name
will be used in the client and in the server.
Warning: if you need to share an array, then the tag in the server should contain the same
number of elements of the tag in the client. If the tag is a class, then the class definition should be
the same in both server and client applications. If you don't follow these rules, unpredictable
results may happen.
Running the TCP/IP Client Module
You can choose to run it auto or manually on the Project->Status, Runtime Tasks Table, item
TCP/IP Client.
After running this program, a small icon will appear in your system tray.
Custom Parameters
There are three parameters you can configure in the Application Configuration (.app) file.
[TCP]
Port=< TCP/IP port number. Default = 1234 >
SendPeriod=< Time in milliseconds the client/server module will update the tag values of the
other machine. Default = 250 >
ConnectRetryTimeout=< Time in seconds the client should retry to connect to the server. Default
= 30 >
The Port parameter should be the same in both the client and server machines.
Only the client module uses the ConnectionRetryTimeout.
OPC (OLE for Process Control)
Introduction
The InduSoft Web Studio OPC Client module enables the InduSoft Web Studio system to
communicate with any device that implements an OPC Server. This module implements the OPC
standard as described in the document "OLE for Process Control Data Access Standard",
available at the site http://www.opcfoundation.com.
