I took some time ‘off’ over the holidays in December to play with some of the new technology and equipment that is now available on the market place. Earlier this past fall I purchased a couple Redigate IoT Gateways from Elecsys. They are nifty units with support for over 60 protocols and the ability to […]

SCADAPack Store and Forward
Little known fact: SCADAPacks can act as a Modbus Store and Forward hub when configured properly. Lesser known fact: SCADAPacks will also Store and Forward Enron Modbus, ROC Protocol, or basically any communications protocol where the first byte of the message is the address, has messages less than 240 bytes and uses Modbus CRC for […]
Kepware has Configuration API!!!
I have been exposed to Kepware a lot more in recent weeks. It is a full featured driver suite, not just for PLC communications anymore! This week in particular I have been tasked with creating over 1200 devices in a single Kepware instance. Good news! They have a REST API that can be enabled and […]
DNP3 Address Mapping on Standard SCADAPack
This month has been a great learning month. I was able to build and complete a small water SCADA system here in Canada (thanks GlobalFlow for the opportunity!) and we made the communications work using DNP3. So this system is built with SCADAPacks talking over a serial radio. Conveniently the master radio is at the […]
Fun with Red Lion DSP – Polling MC-IIIs
The Red Lion DSP is a great little unit. It has mostly the same internals as their G3 HMI line but without the display. This makes it useful as a protocol conversion box, a data collector or a simple web based remote monitoring unit using the built-in web server. BUT it has its quirks; it […]
Setup ClearSCADA Ethernet DNP3 Communications to a SCADAPack (non-E series)
So before the weekend I posted and put up screenshots detailing how to get DNP3 configured on SCADAPack to report up to a ClearSCADA SCADA host server. What follows is the matching ClearSCADA configuration to complete the loop. These screenshots were taken with the latest ClearSCADA 2017, but should also work fine in older (back to […]
MQTT – Is This the Protocol We’re Looking For?
The industrial automation world is just buzzing with internet of things (IoT) news and industrial internet of things (IIoT). SCADA software, polling drivers, field Ethernet to serial gateways and just about everyone else is taking advantage of the new buzzwords. One of the new primary protocols for IIoT devices is MQTT. Last month I attended the Well […]
Report on Exception – A DNP3 Success Story
The year was 2013 and I was working for a client in Northeastern British Columbia (NEBC). We had just finished implementing another multi-well pad RTU installation and it had gone well. The client was preparing for the next set of drilling and completions as well as construction of their new plant. It was the perfect […]
