Ole For Process Control (Opc) Interface - Honeywell Vertex M User Manual

8.7.1 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 "Data Acquisition Computer (rear)" on page 19 for more information.
The Vertex M contains 1331 OPC tags as listed in Table 8-7. 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.
OPC via Ethernet is not recommended for the primary safety system notification.
Tunnel OPC communication outside the Vertex M rack using secure software such as
KepWare OPC Connectivity Suite or Matrikon OPC Tunneller. OPC communication among
Microsoft Windows computers is not highly resistant to cyberattack.
Note: For Vertex M system running FactoryTalk Linx Gateway under Windows 10, please refer to
the Series 3 OPC Interface section.
