Introduction

Active OPC Server is a software package provided by Moxa that operates as an OPC driver for an HMI or SCADA system. It offers seamless connection from Moxa's ioLogik series products to SCADA systems, such as Wonderware, Citect, and iFix. Active OPC Server meets the latest standard of OPC DA 3.0, which allows connections to various kinds of devices and host OPC machines.

Faster, More Accurate Data Collection than Traditional “Pull Technology”

Moxa has pioneered the concept of “active type” OPC software in the automation industry. The patented Active OPC Server offers nonpolling architecture alongside the standard OPC protocol, giving users the alternative of active, push-based communication from Moxa’s RTUs and remote I/O devices. This adaptation of push technology means that I/O status will be updated at the Active OPC Server only when there is an I/O status change, a pre-configured interval is reached, or when a request is issued by a user. This application of push technology cuts metadata overhead, resulting in faster I/O response times and more accurate data collection than traditional pull-based architectures. With Moxa’s “active technology” advantage, users can now instantly receive alarms and real time updates allowing for timely risk response.

Dynamic IP Assignments for Cellular RTUs

For most cellular solutions, each remote modem as well as the central SCADA server are assigned static public IPs when establishing bi-directional communication. Yet cellular network carriers charge higher monthly fees for static, public IPs than dynamic, private ones. Moxa’s ioLogik W5300 series and patented Active OPC Server allow users to implement dynamic IP assignments for the RTUs. The ioLogik W5300 can automatically establish communications with the Active OPC Server using a fixed IP, and the Active OPC Server will receive and register the ioLogik W5300’s IP address and receive or record tag updates accordingly.

One Simple Click Creates Active Tags

Moxa’s RTUs, remote I/O devices, and Active OPC Servers support automatic tag generation, which eliminates the headache of specifying individual target IP addresses, I/O channels, and data formats, while even eliminating any need for editing and importing configuration files. Working from either of Moxa’s ioAdmin or ioSearch utilities, users only need to select specific I/O channels, set the update criteria, and then click a single button for their active tags to be automatically generated and configured.
