How to Log Data From Your S7-1500 via OPC UA using OPC Data Logger

By Tyler Lindsey on Aug 29, 2019 2:00:00 PM


With the relatively recent availability of OPC UA server capabilities in Siemens S7-1500 PLCs, access to live production data is now open to third-party applications. As a result, those applications can now communicate with hardware that was formerly locked behind proprietary communication drivers.

The OPC Data Logger's OPC UA client interface allows users to quickly and easily connect to S7-1500 PLC’s and log data to their preferred data storage option without the need for intermediate applications. This blog post covers the high-level steps involved with logging data from an S7-1500 controller and you can then download the free hands-on guide with detailed steps.

How to Integrate Your S7-1500 via OPC UA using TOP Server for Wonderware

By Marc Holbach on Mar 7, 2019 2:00:00 PM


In recent years, many of our users have let us know they are adopting the latest Siemens technology, particularly S7-1500 controllers.  And, with that adoption of those controllers, users have been asking for connectivity via the symbolic optimized block addressing.  So we added a Siemens Plus Suite to enable connectivity to new and legacy Siemens devices.

This post focuses specifically on the general steps required to integrate S7-1500 controllers by connecting to their embedded OPC UA server using TOP Server for Wonderware.

Building Custom CRCs for Non-Standard Protocols

By Kevin Rutherford on May 17, 2018 2:00:00 PM


If you’ve been following our blog series on custom error detection, you’ll remember that OmniServer provides a large number of pre-defined Error Detection Codes (EDC) for use in different protocols for non-standard device communication.  And, again, it’s not uncommon to find an EDC from a vendor that is not pre-defined due to some specialized handling by the device manufacturer.

As we covered in our previous posts on creating a custom checksum and LRC, OmniServer gives you the ability to build custom EDCs in an OmniServer protocol to handle these situations.  This post, the final of three on custom Error Detection Codes, covers the basics steps to creating a custom CRC (Cyclic Redundancy Check) in an OmniServer protocol.

Building Custom LRCs for Non-Standard Protocols

By Kevin Rutherford on Apr 19, 2018 2:00:00 PM


You may be aware that OmniServer provides a wide variety of pre-defined Error Detection Codes (EDC, also known as CRC, LRC and Checksums) for use in protocols for non-standard device communication.  However, it’s not uncommon to find an EDC that isn’t pre-defined due to some specialized handling by the device manufacturer.

To handle such situations, OmniServer provides the ability to build your own custom EDCs in an OmniServer protocol.  This post, the second of three on custom Error Detection Codes, will cover the basics of creating a custom LRC (Longitudinal Redundancy Check) in OmniServer.

Building Error Detection Codes for Custom Protocols

By Kevin Rutherford on Mar 15, 2018 2:00:00 PM


If you’ve worked with OmniServer to connect your non-standard devices in the past, you may be aware of the large number of pre-defined Error Detection Codes (EDC, also known as CRC, LRC and Checksums) available.  However, as is the nature of custom protocols out there, it’s not uncommon to find an EDC that isn’t pre-defined due to some specialized handling by the device manufacturer.

To that end, OmniServer provides the flexibility to define your own custom EDCs in an OmniServer protocol.  This post, the first of three on custom Error Detection Codes, will cover the basics of creating a simple custom checksum in OmniServer.

Did You Know? Four Key OmniServer Tips For Easier Protocol Creation

By Kevin Rutherford on Feb 8, 2018 2:00:00 PM


As someone who has worked with non-standard device connectivity using OmniServer for over 10 years, I sometimes take for granted the knowledge that I have gained over that time.  If you're anything like me, once you figure out the data you need from your device's protocol document, you just want to get your protocol knocked out as quickly as possible so you can start communicating.

In this post, I'm going to cover 4 key tips that I've learned over the years when working in OmniServer to build a protocol that you may not have realized and that could add convenience and save you a lot of time, which is time you can be spending on other important tasks.

How to Connect, Integrate, or Communicate between Control Systems

By Colin Winchester on Jan 11, 2018 2:00:00 PM

Our Automation 101 blog series is designed to help professionals that are new to the industrial automation space whether at the start of their careers, or moving into the operations technology (OT) world from an IT or other background.

One of the common challenges in Industrial Integration is communications between different brands or manufacturers’ control devices (PLC, DCS, Drives, RTUs, smart sensors).  While most control devices have methods of communication, and some industry standards have helped, they don’t all communicate using the same methods or protocols, and even if they both have the same serial or Ethernet wiring the difference in communication protocols prevents them from passing information.  It’s the same problem you have if someone calls you on the phone, but doesn’t speak the same language.

While, as humans, we may be able to overcome a difference in dialect, machine communication has to be precise and exact.  Small differences in addressing or data formatting can be enough variation to create communications failure. So how do people overcome this challenge?

How to Connect a Non-Standard Device with No Code

By Kevin Rutherford on Jan 4, 2018 2:00:00 PM


l ask you to remember back to our blog post last month where took the information we pulled from a device’s protocol document (in the prior month's blog) and created a custom protocol in OmniServer.  As you’ll recall, our protocol has now been designed.

But how do you go about testing the protocol and proving that it works? This final post in the series takes you through the steps of getting connected and actually troubleshooting your OmniServer protocol.

How to Implement a Custom Protocol for a Non-Standard Device with No Code

By Kevin Rutherford on Dec 21, 2017 2:00:00 PM


So remember in our blog post last month where you just have a protocol document from the manufacturer for a device you need to integrate with your control system?  And for this new device, there is no existing, off-the-shelf connectivity driver or server available.

And remember asking yourself, “How do I connect to this non-standard device?”  With custom software development being very expensive and time-consuming, we discussed a better way using OmniServer.

This post, the second of three, goes beyond the protocol details we gathered from the document in our blog post last month to provide the basics on how to actually use those details to build a working protocol in OmniServer without custom code for a fast, affordable solution with industry-standard client interfaces including as OPC DA and UA.

Your Protocol Document and Integrating a Non-Standard Device

By Kevin Rutherford on Nov 9, 2017 2:00:00 PM


So you've been tasked with bringing data from a new device (maybe a weigh scale or barcode scanner or RFID system) into your HMI/SCADA system.  But you just have a protocol document from the manufacturer.  And for this new device, there is no existing, off-the-shelf connectivity driver or server available.

So what now? Do you contact a custom software development house?  That gets very expensive and time-consuming very quickly.

This post, the first of three, goes through what to look for in that protocol document from the manufacturer to know how to begin using OmniServer to integrate your device without requiring custom code in a fast, affordable manner that provides industry-standard client interfaces such as OPC DA and UA.
