Their built-in reliability features allow the configuration of an unlimited number of redundant OPC servers, redundant networks and redundant devices. Cyberlogic’s Universal OPC Server includes a Health Monitor that continuously verifies the operation of each OPC server, network and device, automatically switching to backups when there is a problem. The built-in unsolicited messaging feature allows the configuration of an unlimited number of nodes that can initiate unsolicited data transmission, eliminating the need for polling for data.
4.1. Gray Simulator:
Gray Simulator is an OPC Server that can be usefull in OPC Client applications debugging. Gray Simulator provides any OPC Client application with simulated COM and DCOM based communications. Use the Simulator to test compliance of any OPC Data Access compatible HMI, SCADA or custom application. This OPC simulator is fully compliant with OPC Data Access 1.00, 2.05a and 3.00.
4.2. Graybox OPC Server Toolkit Demo:
Graybox OPC Server Toolkit lets the programmer to create robust and highly effective OPC Servers within the shortest possible time. This toolkit eliminates the necessity of implementing all of the numerous OPC interfaces and COM programming. Demo version of this OPC Toolkit is available for free. This version is intended for familiarization with our OPC Toolkits.
This software allows OPC clients such as HMI (Human Machine Interface) and SCADA (Supervisory Control and Data Acquisition) systems to exchange plant floor data with PLC (Programmable Logic Controllers).
Supports TCP/IP, UDP/IP or Serial (Direct, Telephone Modem or Radio) I/O.
Master and Slave protocol implementation.
Unlimited level of multi-path (serial / TCP/IP) device redundancy.
Four level of IP Address redundancy.
No need to change OPC Server if you change your hardware or HMI/SCADA software.
One OPC Server can run all supported protocols and link drivers (Ethernet / Serial) simultaneously.
Full time line data analyzer and logging. Great for commissioning or tuning system on site.
Modeless operation. No separate configuration and run mode.
6. SAE Automation
SAEAUT SNMP OPC SERVER:
Exploitation of SAEAUT SNMP OPC Server
The common way for managing industrial and network devices is to run SNMP manager on a workstation while SNMP agents run on devices themselves. In order to be able to integrate the network management into various HMI and SCADA systems with implemented OPC clients, it is very useful to incorporate SNMP manager into OPC server application.
SAE-Automation therefore provides elegant solution for managing computer networks - SAEAUT SNMP OPC Server, which is equipped with devices with implemented SNMP agent functionality.
