Network Interface And Options; Setting Up An Opc Client Application - Honeywell Vertex M Technical Handbook

Vertex M 24-Point Continuous Monitor
TM
A.2 OLE for Process Control (OPC)
Interface
The primary method of alarm and fault annunciation
used by the Vertex M Gas analyzer relies on the Allen
Bradley SLC500 PLC system installed in the base
enclosure using optional fieldbusses or contact closure.
A secondary method for annunciation and data
access is available via the Ethernet network port on
the Vertex M Data Acquisition System using OPC.
Concentration data as well as alarm and fault status
are available through this interface. The OPC drivers
are automatically initialized at startup of the application,
enabling the Vertex M to act as an OPC Server. The
user may connect to the Network interface Cards RJ45
Port at the rear of the data Acquisition System See
Section 1.2.7 Data Acquisition Computer
The Vertex M contains 1331 OPC tags as listed in
Table A-3. Tag Names. Many of these are present for
historical reasons and have low utility for an external
HMI system. The column "recommended for most HMI
systems" is provided to help separate the useful from
the obscure. The number of recommended tags is 317.
CAUTION
OPC via Ethernet is not recommended for the primary
safety system notification.
CAUTION
Tunnel OPC communication outside the Vertex M rack
using secure software such as KepWare OPC Connectiv-
ity Suite or Matrikon OPC Tunneller. OPC communication
among Microsoft Windows computers is not highly resistant
to cyberattack.
