OmniServer's main purpose is enabling connectivity without custom code for devices that use ‘non-standard’ protocols to communicate such as weight scales, barcode readers, and printers.  And OmniServer does that in a more efficient and cost-effective manner than writing custom code.

Furthering the goal of efficiency and cost-effectiveness, you may or may not be aware that OmniServer supports CSV import and export for speedy configuration of many things including topics, devices and, in the actual protocol itself, items, registers, topic variables and even messages.  On larger projects, this provides a substantial time savings.

In this post continuing our "OmniServer Did You Know?" blog series, we will cover how to use CSV import and export in OmniServer to facilitate faster configuration on larger protocol implementations.

If you're familiar with OmniServer, you know that OmniServer is frequently used for accessing information from devices that use ‘non-standard’ protocols to communicate such as weight scales, barcode readers, and printers either over serial connections or Ethernet connections.

With the advent of touchscreen technology and the increasing availability and familiarity with drag-and-drop functionality across computer systems and applications, we feel it is important to evolve the OmniServer user experience to be more inline with current technologies and user expectations regarding ease-of-use.

In this blog post, we will cover a visual protocol editor we've been working on for OmniServer, showing you the key enhancements to the user experience that will make integrating your non-standard devices easier than ever.  And you'll be given the chance to download the free trial.

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

7 min read

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.

If you're familiar with OmniServer, you likely already know how OmniServer is commonly used to retrieve information from devices that use ‘non-standard’ protocols to communicate such as weight scales, barcode readers, and printers either over serial connections or Ethernet connections.

However, with the advent of USB connectivity, many such devices that would have traditionally been a serial/COM device now physically connect to a machine via USB, instead.

Continuing our "OmniServer Did You Know?" blog series, we will cover how OmniServer can easily connect to USB or serial-to-Ethernet devices that are mapped virtually as Serial/COM devices.

When working with non-standard protocols based on protocol documentation from a device vendor, there will always be some expected amount of testing, trial-and-error and troubleshooting in order to fine tune communications with a device.

Continuing our "OmniServer Did You Know?" blog series, this blog post focuses on how to use the built-in Item Values window in the OmniServer diagnostic tools and the included OPC Test Client to test communications using OmniServer.

Demystifying Modbus Function Codes

12 min read

By Kevin Rutherford on Dec 13, 2018 2:00:00 PM


With the wide range of devices that use Modbus for their communication protocol, you'll find many different interpretations, terminology and labels with respect to how to access different types of data in those devices.  Sometimes a device manual might only refer to the supported Modbus function codes and the range of offsets available for those function codes.

In this blog post, I will step through the specifics of Modbus function codes and how they pertain to addressing, and how they affect what addresses to use in TOP Server for Wonderware applications.

Did You Know? How to Recover from Device Errors with OmniServer Error Messages

7 min read

By Kevin Rutherford on Nov 7, 2018 2:00:00 PM


With any communication server for collecting process data, there has to be a reliable mechanism built-in for dealing with error responses from the underlying devices.  This is true even for OmniServer as a user-configurable communication server.

Continuing our "OmniServer Did You Know?" blog series, this blog post focuses on how to use error messages and notification items in an OmniServer protocol to properly handle error responses or conditions received from your non-standard process devices.

Demystifying Modbus Register Addressing with TOP Server for Wonderware

I'm sure you've all at least had some interaction with Modbus, working in the automation industry.  It's one of the most widely used protocols (if not the most widely used) in the world.  Which is both its blessing and its curse, to some extent.

Given how long Modbus has been around and in use as an "open" protocol (starting in 1979), there have been many different interpretations of Modbus throughout the years.  And with those different Modbus interpretations, much confusion about the different terminology for accessing data.

In this blog post, I will step through the basics of Modbus addressing including how offsets come into play, and how they affect what addresses to use in TOP Server for Wonderware applications.
