Demystifying Modbus Function Codes

Posted 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.

Demystifying Modbus Register Addressing with TOP Server for Wonderware

Posted by Kevin Rutherford on Oct 11, 2018 2:00:00 PM

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.

Did You Know? How to Setup Chained Messages in OmniServer

Posted by Kevin Rutherford on Oct 4, 2018 2:00:00 PM

In a nutshell, OmniServer's purpose is to retrieve information from devices that use ‘non-standard’ protocols to communicate such as weight scales, barcode readers, and printers.

Sometimes with some protocols, simply sending one message to a device, or doing nothing but simply transferring data to a client isn't enough. There are some more complex protocols where you will need to send a series of messages to the instrument, or respond to an event coming in from the device or to handle a sequence of handshaking messages. This is where "chained messages" come into play in an OmniServer protocol.

In this second post of a follow-up to our "OmniServer Did You Know?" blog series, we will cover how to chain multiple OmniServer command/request messages together in a protocol to flexibly handle such complex protocols.
