Building Custom CRCs for Non-Standard Protocols

Posted 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.

Video Tutorial: EFM Collection for Enron Modbus

Posted by Kevin Rutherford on May 10, 2018 2:00:00 PM

Common in the oil and gas industry, flow computers and devices store historical EFM (Electronic Flow Measurement) data used for analysis, custody transfer and production optimization.  Enron Modbus, which is a version of the open Modbus protocol, is a frequently used communication protocol by many EFM devices including but not limited to Schneider SCADAPack, ThermoScientific AutoPilot, Cameron NuFlo Scanners and many others.

In this video blog, I'll show you how to get started using our Enron Modbus driver to connect and gather real-time and EFM data from Enron Modbus devices from Wonderware applications.

Video Tutorial: Conditional Logging to Text File from Non-Standard Devices

Posted by Kevin Rutherford on May 3, 2018 2:00:00 PM

OmniServer Wedges, included with OmniServer Professional Edition, are built-in components providing powerful, supplemental capabilities that expand the functionality of OmniServer beyond its core connectivity and data parsing abilities for non-standard devices.

The OmniServer File Wedge allows you to log your device data to any text file, including CSV, with a highly configurable format and flexible conditions.  And this ability is built into OmniServer, eliminating the need for separate external components.

In this video blog, I'll show you how to get started using the OmniServer File Wedge to easily log process data based on specified conditions, making it possible to monitor trends in your process and easily troubleshoot any issues that are discovered.

Video Tutorial: Finding Problem ArchestrA Objects Quickly and Easily

Posted by Kevin Rutherford on Apr 26, 2018 2:00:00 PM

If you're a Wonderware System Platform (ArchestrA) user, how frequently do you find yourself searching for all of the undeployed object instances and object instances with errors, warnings and changes pending in your ArchestrA galaxy? How much time and effort is involved with those searches?

The following short video blog demonstrates how you can streamline your troubleshooting process with a built-in Status View for your ArchestrA IDE, saving time and effort and allowing you to spend more time solving problems rather than trying to find them.

Building Custom LRCs for Non-Standard Protocols

Posted 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.

A New Twist on Machine or Process Troubleshooting Charts

Posted by John Weber on Apr 12, 2018 2:00:00 PM

It’s very common to make process flow charts or machine operational flow charts to help document and aid in troubleshooting.  These charts end up in manuals, operator and maintenance training, and get pulled out when something is wrong and put to use.

During a recent trip, I learned from one of our partners about how he’s seeing more users and machine builders take those paper drawings to a new level of interactivity.

Video Tutorial: Easy Integration of Your OPC DA/UA Data with MS Excel

Posted by Win Worrall on Apr 5, 2018 2:00:00 PM

With DDE (Dynamic Data Exchange) fast becoming obsolete technology (Microsoft superseded DDE with OLE years ago), OPC DA and, more recently, OPC UA data sources have become the primary go-to for process data integration.  Recently, Microsoft even disabled certain DDE functionality in MS Office applications due to security concerns and malware exploitation targeting the DDE interface.

But the usefulness of MS Excel for data analysis across many industries even today is still undeniable and the primary mechanism for MS Excel to connect to a data source is via DDE.  So what do you do if you're still using MS Excel for process data analysis and reporting via DDE?  What's the alternative?

The following short video blog demonstrates step-by-step how to easily read/write data from process data sources (OPC DA and OPC UA Servers) using MS Excel (without DDE) with the Cogent DataHub.

Video Tutorial: Sending Email/Text Notifications from Non-Standard Devices

Posted by Kevin Rutherford on Mar 29, 2018 2:00:00 PM

OmniServer Wedges, which are included with OmniServer Professional Edition, are built-in components that provide powerful, supplemental capabilities that expand the functionality of OmniServer beyond its core connectivity and data parsing abilities for non-standard devices.

The OmniServer Email Wedge allows you to send your device data as an email message or text in a highly configurable format with configurable conditions.  And it provides this ability built into OmniServer, eliminating the need for separate external components.

In this video blog, I'll show you how to get started using the OmniServer Email Wedge to send timely email or text notifications to your key personnel based on specified conditions, allowing those individuals to quickly take the appropriate action to minimize any related loss or downtime that might occur.

Building Error Detection Codes for Custom Protocols

Posted 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.
