OPC Server Architecture Sample Clauses

The OPC Server Architecture clause defines the technical framework and requirements for how an OPC (OLE for Process Control) server is structured and operates within a system. It typically outlines the necessary components, communication protocols, and data exchange mechanisms that the server must support to ensure interoperability with client applications and other industrial automation systems. By specifying these architectural standards, the clause ensures reliable data flow, system compatibility, and efficient integration, thereby reducing the risk of miscommunication or system failures in automated environments.
OPC Server Architecture. The OPC specifications describe three different OPC servers, where each of the servers can work on their own. • Data Access • Alarms and Events • Historical Data Access OPC Data Access [2,3] defines interfaces for reading and writing information to and from the control system and it makes it possible to browse the system for information. Alarm and Events contains functions for handling alarms and events in the system. An alarm is an abnormal condition in the system and an event is some kind of system change or system error. Historical Data Access is used for handling historical process data, e.g. saving process states in a database. The OPC standard specifies two sets of interfaces for communication between a client application and a server; Custom interfaces and Automation interfaces. All interfaces specified by OPC are COM interfaces. The Custom interface is designed for high throughput applications and is used by applications developed in C++. The Automation interface is provided primarily for Visual Basic applications.

  • Server Software Subject to the terms and conditions of this ▇▇▇▇, Vocera grants you the non-exclusive right to (i) install and run (“Use”) the Server Software on computer systems (each, a “Server Computer”) located at End User’s Facilities in the geographic territory designated above (“Territory”); (ii) to Use the Client Software in conjunction with Authorized Client Devices and such Server Computers; and (iii) for pilot licenses for certain Software provided on a trial basis, use such Software for the limited term specified by Vocera in writing. You may Use the standard Server Software on one primary Server Computer (or a primary cluster of computers suitably configured for productive use of the Server Software). You may install backup copies of the Server Software on backup Server Computers to provide redundancy in the event of failure of the primary Server Computer(s) but, unless you have acquired additional licenses or a failover license from Vocera, you may not run such backup or additional copies concurrently with the primary copies. Vocera grants you the right to use the applicable License Key issued by Vocera only to enable Use of the Server Software in conjunction with the licensed Server Computers. Server Software may be licensed for a Subscription Term as specified in the Quote.

  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at a P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • Access Toll Connecting Trunk Group Architecture 9.2.1 If WCS chooses to subtend a Verizon access Tandem, WCS’s NPA/NXX must be assigned by WCS to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG. 9.2.2 WCS shall establish Access Toll Connecting Trunks pursuant to applicable access Tariffs by which it will provide Switched Exchange Access Services to Interexchange Carriers to enable such Interexchange Carriers to originate and terminate traffic to and from WCS’s Customers. 9.2.3 The Access Toll Connecting Trunks shall be two-way trunks. Such trunks shall connect the End Office WCS utilizes to provide Telephone Exchange Service and Switched Exchange Access to its Customers in a given LATA to the access Tandem(s) Verizon utilizes to provide Exchange Access in such LATA. 9.2.4 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Exchange Access to allow WCS’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to a Verizon access Tandem.

  • Configuration Management The Contractor shall maintain a configuration management program, which shall provide for the administrative and functional systems necessary for configuration identification, control, status accounting and reporting, to ensure configuration identity with the UCEU and associated cables produced by the Contractor. The Contractor shall maintain a Contractor approved Configuration Management Plan that complies with ANSI/EIA-649 2011. Notwithstanding ANSI/EIA-649 2011, the Contractor’s configuration management program shall comply with the VLS Configuration Management Plans, TL130-AD-PLN-010-VLS, and shall comply with the following:
