2. Getting Started
2.1 Introduction to the PHD OPC Server
The PHD OPC Server is a Uniformance component that implements OLE for Process Control
(OPC) interfaces as a method of access to a Uniformance Process History Database (PHD)
Server. The interfaces enable client applications to access a single Uniformance PHD Server.
A Uniformance PHD Server stores variable data from a variety of process related sources. All
data values stored in a PHD Server are maintained over time in history archives. The PHD
Server provides interfaces through which clients may access the current or historical values
from its storage.
The PHD OPC Server is an independent executable program – it can reside on the same
machine as the PHD Server or on a remote server.
The OPC standard interface specifies a standard set of interface semantics for access to data
values. The PHD OPC Server is compliant with both the OPC DA and OPC HDA standards,
described as follows:
OPC DA The OPC Data Access (DA) standard interface allows clients to gain
access to real-time (current) data values maintained by a PHD Server.
OPC HDA The OPC Historical Data Access (HDA) standard interface allows clients
to gain access to historical data values maintained by a PHD Server.
Supported OPC standards
The PHD OPC Server is compliant with the following OPC standard versions:
•DA Versions 1.0A, 2.05, 3.0
•HDA Versions 1.1, 1.2

2 Getting Started
2.2 PHD OPC Server Requirements
12 •Uniformance - PHD OPC Server User Guide
2.2 PHD OPC Server Requirements
Hardware environment
Item Requirement (minimum)
CPU Intel Pentium Pro
Memory 64 MB
Hard Disk 128 MB free space
Software environment
Item Requirement
Operating System •A supported Microsoft Windows operating system. (See the
Uniformance Software Change Notice for details.)
•Windows NT File System (NTFS) is required for security
purposes.
PHD OPC Server Requires the installation of PHD Server software on at least one
computer system within the same network domain.
Network environment
Item Requirement
Network Protocols Ethernet, TCP/IP, Microsoft application layer software (RPC and
DCOM). One of the following name services must be available:
•DNS
•WINS
•Local Host File
2.3 Where to Install PHD OPC Server Software
During installation of the PHD OPC Server software from the Uniformance DVD, you must
choose an install type - Client or Server:
Install
Type Description
Client Installs the OPC Client DLLs and registers the OPC Server name
on this machine.

2 Getting Started
2.4 PHD OPC Server Registry Settings
Uniformance - PHD OPC Server User Guide •13
Install
Type Description
Server Installs the complete OPC server, registers the OPC Client DLLs,
and registers the OPC Server name.
You must install Server on one of the following:
•the PHD Server node,
•the client node, or
•another node.
If you install Server on a separate node from the PHD Server, then the PHD OPC Server will
use the PHD Server's API Server instead of accessing the PHD Server directly. You should
be aware that this connection counts against the maximum number of users for the API
Server. (For information on the APIServer registry settings, refer the PHD System Manual,
pim0301.pdf.)
You only need to install Client on client nodes that are separate from the Server node.
Note: For security reasons, Honeywell recommends that Server and Client be on the same
side of a firewall as the PHD Server; otherwise, OPC requires that you open additional ports
in the Firewall. Since OPC uses DCOM, and DCOM uses many dynamically assigned ports,
OPC will not work well with a firewall.
REFERENCE: For the software installation procedure, refer to the PHD Installation Guide
(in6001.pdf).
2.4 PHD OPC Server Registry Settings
The following registry settings are read-only when the PHD OPC Server process is started up.
If you modify the registry settings while the PHD OPC Server is running, these will not be
read until the PHD OPC Server is restarted.
To enable/disable tag browsing
PHD OPC Server tag browsing is disabled by default. The tag browsing can be enabled by
changing the registry setting under the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Honeywell\Uniformance\OPCServer
Set the following REG_DWORD value to control the PHD OPC Server’s browse capabilities:
BrowseMode = 0 Automatic Mode
- Disabled if on PHD Server machine

2 Getting Started
2.4 PHD OPC Server Registry Settings
14 •Uniformance - PHD OPC Server User Guide
- Enabled if on Client machine
1 Always enabled
2 Always disabled
Cached browsing
Tag browsing has the potential to be a slow and memory intensive process. Browsing may be
performed in a cached mode. If cached browsing is enabled, all PHD tags "queried" during
the first browse are "cached" in memory. Any subsequent requests to browse for tags will go
to this cache for tag information. If disabled, each browse request will go to PHD for tag
information. The advantage of caching is that any subsequent browse request is quicker after
the first request; however, with cached browsing enabled, you will not see updated or new
PHD tags through the browse.
The cached browsing can be enabled by changing the registry setting under the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Honeywell\Uniformance\OPCServer\
CacheBrowseInfo
Valid options are:
0 : Disabled
1 : Enabled
To enable AFM tag routing and put download
For the output of an Advanced Formula Manager (AFM) tag to be routable and put
downloadable, the HDAInsertsUsePutData registry key MUST have value of 1.

3. Configuring the PHD OPC Server
3.1 Overview
This section shows you how to configure the PHD OPC Server in your system.
When you install the PHD OPC Server in your system, a default set of system parameters is
created in the Windows Registry.
You may need to modify the default configuration for the PHD OPC Server on your system to
accomplish either of the following:
•To establish specific user rights to launch, access, and configure the PHD OPC Server.
•To run the server on a remote computer.
3.2 View/Modify DCOM Configuration of PHD OPC Server
This section provides information regarding the configuration of DCOM server properties
using the Microsoft DCOMCNFG utility.
The PHD OPC Server is implemented using the Microsoft Distributed Component Object
Model (DCOM) technology. Its execution environment is defined by the system level
settings established for DCOM components. These settings can be customized using the tool
provided by Microsoft (DCOMCNFG).
DCOM has settings for:
- the machine default, and
- each COM server.
You can view/modify the DCOM settings for the individual PHD OPC Server components by
selecting the component name (Uniformance PHD OPC DA Server or Uniformance PHD
OPD HDA Server).
The machine default settings are used when there are no custom settings for the specific COM
(OPC) server. If a server has custom settings, then changes in the default settings have no
effect for this server.
REFERENCE – EXTERNAL
For information on OPC DCOM communications with Windows XP and
Windows 2003 , refer to the white paper 'Using OPC via DCOM with XP SP2.pdf',
available at http://opcfoundation.org. This white paper also applies to
Windows 2003 SP1 and greater.
