AVEVA System Platform to TOP Server via OPC UA Expands Connectivity

23 min read

Many AVEVA users are probably already aware of the native connectivity options they have for interfacing with different systems. Many AVEVA users have also turned to TOP Server over the years, both for standardizing device connectivity in a single server and for drivers/protocols not available as native AVEVA options.

Those users of AVEVA System Platform have traditionally connected to TOP Server directly via either its native SuiteLink interface or OPC DA Classic. AVEVA's OI Gateway provides those users the additional option of connecting to OPC UA data sources, for easier and more secure remote connections to such data sources.

In this blog post, we will cover the basic steps to connect AVEVA System Platform to TOP Server via OPC UA, expanding device connectivity options for AVEVA users.

If you are reading this post, chances are you have configured your TOP Server project and are communicating with your devices successfully. Perhaps, you also have a client application successfully writing and/or reading to or from TOP Server. Did you know all TOP Server drivers provide several different Scan Modes for controlling how client requests affect the polling frequency for your configured devices? In fact, these Scan Modes apply to all client connection types including OPC UA, OPC DA and AVEVA SuiteLink.

Continuing our Tech Support Corner blog series, this short post will discuss the five Scan Mode options available in the TOP Server Device Properties. Each Scan Mode serves a different purpose depending on your specific scenario. We will explain each mode, giving you a better understanding of which mode is best for your situation. Correctly setting the Scan Mode to match the capabilities of your device will help to provide optimal performance for your automation system.

AVEVA users already have a wide range of connectivity options for interfacing with different systems. For many years, OmniServer has been expanding that connectivity to include non-standard, non-PLC type devices that don't have an existing off-the-shelf communications driver. Users of AVEVA System Platform have traditionally connected to OmniServer via either the native SuiteLink interface or OPC DA Classic. AVEVA's OI Gateway provides those users the additional option of connecting to OPC UA data sources, for easier and more secure remote connections to such data sources.

In this blog post, we will cover the basic steps to connect AVEVA System Platform to OmniServer via OPC UA, expanding non-standard device connectivity options for AVEVA users.

AVEVA users already have a wide range of connectivity options for interfacing with different systems. Cogent DataHub® also supports an extensive selection of connectivity to different systems that users sometimes need to access from AVEVA System Platform. Users of AVEVA System Platform have traditionally connected to DataHub via OPC DA Classic. AVEVA's OI Gateway provides those users the additional option of connecting to OPC UA data sources, for easier and more secure remote connections to such data sources.

In this blog post, we will cover the basic steps to connect AVEVA System Platform to Cogent DataHub via OPC UA, expanding connectivity options for AVEVA users.

Accessing AVEVA System Platform with TOP Server via OPC UA

Are you an AVEVA System Platform user but you also have some other client or system (HMI, SCADA, other) and need that system to access data from System Platform?  It's a use case that sometimes occurs if your company is acquired another company and a non-AVEVA HMI/SCADA came as part of the assets.  Or perhaps your company merged with another and now your AVEVA system is expected to integrate with other systems.  Your options for sharing data largely depend on what software interfaces these "other systems" support.

In this blog post, I'll discuss how to share your AVEVA System Platform 2020 (or newer) data via OPC UA (without using OI Gateway) using the TOP Server OPC UA Client driver for situations where you have another non-OPC UA capable client application that needs access to process data in your AVEVA system.

Accessing AVEVA System Platform with OPC Router via OPC UA

A common use case that we encounter with many AVEVA users is the need to share data from System Platform with some other client or system (HMI, SCADA, other). It's not uncommon for a company to be acquired by another company and its assets and a non-AVEVA HMI/SCADA came as part of the assets.  Or perhaps a system is being add with limited interfaces for external connectivity.  Your options for sharing data largely depend on what software interfaces these "other systems" support.

In this blog post, I'll discuss how to share your AVEVA System Platform 2020 (or newer) data via OPC UA (without using OI Gateway) using the OPC Router for situations where you have another non-OPC UA capable client application that needs access to process data in your AVEVA system such as an ERP system, IIoT platform, web service and more.

DCOM Hardening & Your Alternatives to Eliminate Security Risk & Stress

10 min read

If you’re reading this post, you’ve almost certainly at least heard of DCOM. And, possibly, you’re one of many who have struggled over the years with the trials of configuring remote OPC Classic connections between machines where DCOM inevitably increased your time and difficulty for what should be a relatively painless task.

DCOM Hardening is Permanent in 6d 1h 34m 0s

DCOM hardening with no option to disable it is coming up fast - March 14, 2023. If you haven't already made a plan to either migrate away from DCOM communications entirely or address how to keep your process systems that will still rely on remote OPC Classic over DCOM working reliably, time is running out. Downtime is costly and a system that is using OPC Classic and hasn't been evaluated to determine the effects of DCOM hardening could be vulnerable to communication breaks.

This blog post discusses 6 types of options to relieve DCOM hardening pain. These include alternatives to DCOM that cover a range of use cases depending on what software you already have installed and your existing system architecture. We also have a comprehensive guide that you'll be able to request that addresses what DCOM changes will be needed if you're not in a position to migrate currently.  Our technical support team are also willing to discuss your specific requirements with you, so you're not on your own out there!

Are you or have you ever been in a situation where you were working with both an AVEVA solution and some other client or system (HMI, SCADA, other) and needed to share data?  Perhaps your company acquired another company and its assets and a non-AVEVA HMI/SCADA came as part of the assets.  Or perhaps your company merged with another and now your AVEVA system is expected to integrate with other systems.  Your options for sharing data largely depend on what software interfaces these "other systems" support.
