4.3 OPC – (OLE for Process Control)
CMS is equipped with an OPC data server which can publish its process variables across an
Ethernet network. The CMS software is compliant with OPC version 2.0. When using OPC we
recommend the use of a NTP network time server to ensure the CMS time is synchronized with the
client system.
4.3.1 Connecting
The following information can be used to connect and view the process variables using an OPC
Client. Please be sure to properly configure any firewall to allow OPC communication.
OPC Server Name = OPC_Intek-exe
Remote Machine Name = <CMS IP> or <CMS Network Name>
Client DCOM Settings
Authentication Level: None
Impersonation Level: Identify
Security: Default
4.3.2 Adding Process Variables
Once connected to the CMS system there will be a tree view of the available process variables
organized by instrument type. Select or expand the type of instrument you would like to view outputs
from (FM, PT, RV, TC, MA, etc). Then select or expand the specific instrument you would like to
monitor. Each instrument contains at least one process variable denoted by PV#. PV# will then have a
series of sub values either Label, Units, and/or Value depending on the instrument type. These sub
values can be added to a group or viewed individually to get the current outputs of the desired
instrument. Other variable options are available and vary by client. Please consult your OPC client
manual for more specific settings.
A flow meter (FM) outputs two process variables marked as PV1 and PV2. An example to view
the current information for PV1 flow meter 12345-1 is shown in Table 10. A complete list of all OPC
published variables can be found in SECTION 8 - CUSTOM INFORMATION.
