If you're reading this, you likely have at least one Siemens S7 PLC on your network being used in your industrial process and need to integrate data from that process. And if you're still using traditional Siemens variable-type addressing to access your S7 controllers, you need traditional S7 TCP/IP protocol connectivity.

In this video blog, I'll show you how to get started using our Siemens TCP/IP Ethernet driver to connect and gather real-time process data from Siemens S7 PLCs for AVEVA software applications and other clients.

AVEVA users have a range of native connectivity options for interfacing with different systems. OPC Router also supports connectivity to variety of different systems that users sometimes need to access from AVEVA System Platform. Users of AVEVA System Platform can leverage OI Gateway to easily and securely connect to OPC Router via OPC UA for connections to many other data sources.

In this blog post, we will cover the basic steps to connect AVEVA System Platform to OPC Router via OPC UA, enabling additional connectivity options for AVEVA users to systems such as SAP (and other ERPs), a variety of relational and other databases, conversion of file data including CSV, XML, JSON and others, IIoT systems including REST and SOAP web services and MQTT brokers and more.

Did You Know? Using Special Characters in OmniServer Protocol Messages

5 min read

By Kevin Rutherford on Oct 5, 2022 10:00:00 AM


As someone who has worked with non-standard device connectivity using OmniServer for over 16 years, I consider myself well-versed in some of the more obscure nuances of certain protocols that a user might need to implement and how to do so in OmniServer.  It's very common for non-standard device protocols to simply be some combination of ASCII alpha-numeric characters with some special characters mixed in for starting messages, terminating messages or as delimiters.

Many OmniServer users may not be aware, though, that there are certain ASCII characters that are used in OmniServer protocol messages that have special meaning. So when you come across a device protocol that requires those characters to be sent or receive as-is (namely backslashes, curly braces and square brackets), there is some special handling required when configuring your OmniServer protocol .

Returning and expanding our "Did You Know" OmniServer blog post series, I'll cover the usage of some common special syntax characters for OmniServer protocol messages and how to, when needed, escape their special status in the message so they can be treated as their original ASCII equivalent instead.

Converting Non-OPC UA System Data for OPC UA Clients with OPC Router

9 min read

By Kevin Rutherford on Sep 15, 2022 2:00:00 PM


OPC Router provides connectivity to a wide range of data sources including ERP systems such as SAP, a variety of relational and other databases, conversion of file data including CSV, XML, JSON and others, IIoT systems including REST and SOAP web services and MQTT brokers and more. It's often necessary for OPC UA client applications (such as HMIs, SCADAs and other software clients) to need access to such data sources. OPC Router also supports acting as an OPC UA server.

In this blog post, we will cover the basic steps to map such non-OPC UA data sources supported by OPC Router to OPC UA nodes/items for access by external OPC UA clients.

Tech Support Corner: Understanding TOP Server Channel & Device Limits

4 min read

By Zachary Parham on Sep 8, 2022 2:00:00 PM


Our team often gets questions about the extent to which our products can be used. It’s important to differentiate between technical versus practical limits when discussing what is and is not possible.

Continuing our Tech Support Corner blog series, I will be providing some insights into how many channels, devices, and tags it is technically possible to set up in TOP Server while also highlighting some practical rules of thumb to observe to ensure the best performance.
