Building Technologies MM8000 OPC Connectivity Configuration Guide
Fire Safety & Security Products 06.2007
1 Introduction
This is a guide to the software configuration procedures for the subsystems provid-
ing an OPC server interface. In addition, the SIMATIC S7 connectivity to MM8000
via OPC is discussed.
For a complete guide to the configuration process, this manual should be used with
the MM8000 Installation, Configuration, and Commissioning manual (document
no.A6V10062413) and with the DMS8000 Connectivity Guides for
1.1 Overview of OPC connectivity in MM8000
OPC is a widely accepted industrial communication standard that enables the ex-
change of data between multi-vendor devices and control applications without any
proprietary restrictions. OPC is a Client / Server technology. One application acts
as the server providing data, and another acts as a client using data.
DMS8000 systems can provide both OPC server and OPC client functions in
various configurations.
MK8000 OPC Server: MM8000 option and Stand-alone product
In MM8000, in order to connect additional OPC client stations and enable them to
communicate with the field units controlled by the MM8000 server and stations,
you can enable the MK8000 OPC server functions, as described in the MM8000
ICC manual (document no.A6V10062413).
In addition, MK8000 can run as a stand-alone OPC Server, without MM8000.
Note that this document does not discuss the MK8000 OPC server. Instead, refer
to MK8000 ICC manual (document no.A6V10062407).
OPC Client functions in MM8000
In case MM8000 has to connect to OPC server that provide the data connection to
field control units, the MM8000 OPC clients functions are used, as described in this
document.
Software version
The supported OPC version is Data Access 2.0.x.
Limitations
Multiple OPC channels can be programmed with no limitations on top of the gen-
eral maximal system dimensioning (please refer to latest edition of MM8000 Data-
sheet. Document no. A6V10062415).
Software License
A specific license id required for enabling the OPC client functions in MM8000. The
license defines the allowed number of connections to OPC servers.
Also, the subsystems (physical control units) and points (physical and logical ob-
jects, but not the OPC items) configured in Composer for connecting via OPC are
charged according to the general sales policy related to the system size.
 Please refer to the local sales support for more details about MM8000 licenses.
Windows configuration: DCOM settings
In case of network-distributed solutions, DCOM security must be configured in or-
der to enable the correct communication between PCs over the network.
 For more information about DCOM settings, please refer to section 5 on page
