Advanced MatrikonOPC Server Functions
Advanced functions make OPC integration easier, allowing MatrikonOPC’s latest
servers to better process data, and make OPC solutions more secure and
reliable. MatrikonOPC Server Advanced Functionality consists of a collection of
components engineered to work together in various combinations depending on
each MatrikonOPC server’s requirements.
||OPC Security: Native support
for the OPC Foundation's OPC Security specification is crucial for implementing
secure OPC architectures. Instead of relying on global, DCOM based,
"all-or-nothing" OPC data access permissions, this function offers complete
control over item browsing, adding, reading, and writing - on a
per-user-per-item basis. Granular control over data access helps prevent
accidental or intentional un-authorized OPC data access. This role based
security adds another layer to a systems overall Defense-in-Depth strategy.
||Device Communication Redundancy:
Maximize OPC data reliability by enabling the OPC Server to access multiple
data-sources in a redundant fashion without the need for specialized hardware
and/or additional custom software.
||Data Calculations: MatrikonOPC
servers allow processing of raw OPC item data on the OPC Server side. Using a
variety of math functions, constants, and equations – MatrikonOPC servers help
reduce OPC client side computing requirements and network traffic volume by
performing data conditioning right on the OPC Server side.
||Alarms and Events: MatrikonOPC’s
Server enables users to trigger Alarms and Events based on the OPC item’s
value. Also, Alarms and Events can be triggered based on the calculated value
of pre-processed items using the powerful Calculation Engine. The MatrikonOPC’s
Advanced Framework enables client filtering by event type, severity, and
category and is OPC Compliant.
||Maximum Interoperability: Strict
adherence to the OPC Foundation’s OPC DA, OPC HDA, and OPC A&E
specifications. Backwards compatible and fully compliancy tested, MatrikonOPC
servers strictly adhere to the OPC Foundation’s specifications to ensure
maximum interoperability with other vendor’s OPC products.
||Offline Mode: developed to
aid system-integration; this functionality simplifies OPC Server configuration
by allowing OPC Clients to access data from all configured OPC items even when
the underlying data-source is not available. For example: during plant
commissioning; instead of delaying HMI graphic screen testing until the end of
the project, when all the OPC Servers' data-sources are available - such tests
can now be run at any time using the Offline Mode random test data.
||User Defined Tag names: Enables
the creation of virtual OPC Items on any MatrikonOPC server. Whether used for
testing or for user-defined status indicators, MatrikonOPC Aliasing extends all
MatrikonOPC servers’ to work with user-configured OPC items.
