CTI 2500-OPC KEPServerEX OPC and Communications Server

Description

2500-OPC is an OPC and Communications Server enabling Ethernet

communications between Windows-based PC applications and the

CTI 2500 Series™ PLC system.

2500-OPC works with the Ethernet commu nications ports on

2500-Cxxx Processors and 2572 / 2572-A Ethernet Adapter Modules.

Features

OPC Connection Security

The Secure by Default feature enables us ers to select whether or not

the server should respect the DCOM security settings as they appear

in the DCOM Configuration Utility. When this setting is enabled, users

can select the authentication, launch and access security requirements

through the DCOM Configuration Utility. This allows us ers to specify

the level of security they want to implement and also restrict access

for certain users and/or applications.

Process Mode

KEPServerEX runtime Process features are used to specify how the

servers runtime process mode will operate and utilize PC resources.

It is used to specify whether the server will be running as System

Service or Interactive.

KEPServerEX also allows you to set its own process priority giving the

server priority access to resources.

Processor Affinity

This parameter allows the user to specify which CPUs the server can

be executed on when it is run on PCs containing more than one.

Host Name Resolution

KEPServerEX allows for host name resolution which is an alias assigned

to identify a TCP/IP host or its interfaces. Host names are used in all 

TCP/IP environments and user can specify host name instead of an IP

address when using KEPServerEX v5.

OPC UA (Unified Architecture)

KEPServerEX supports OPC UA Client Connections and the OPC DA

data set.

OPC AE (Events)

KEPServerEX exposes event log data (Events) to OPC AE Client

applications. The Event server works in runtime and service modes

supporting 3 Event categories (Information, Warning, Error).

KEPServerEX also supports AE client filtering by event type, severity,

and category and is OPC Compliant.

Server Administration Properties

The User Management system of the server controls what actions a

user can take within a server project. The User Properties dialog is

used to configure the name, password and privileges available for

each account.

Auto Demotion

The Device Auto-Demotion parameters allow a driver to temporarily

place a device off scan in the event that a device is not responding.

By placing a non-responsive de vice off-line, the driver can continue

to optimize its communications with other devices on the same

channel by stopping communi cations with the non-responsive device

for a specific time period. After the specific time period has been

reached, the driver will reattempt to communicate with the non

responsive device. If the device is responsive, the device will be placed

on-scan, oth erwise it will restart its off-scan time period.
