A data set says what an IED can send. A report control block says when, why, how much detail, and to whom. Every reporting problem in a substation — missing events after a comms drop, a client that never receives anything, reports flooding the station bus during a fault — traces back to an RCB attribute somebody set… Read More: IEC 61850 Report Control Blocks: BRCB and URCB Explained »
The confusion is understandable. Both protocols are built on MMS. Both use the same OSI upper-layer stack. Both listen on TCP port 102 and 3782. Both show up in Wireshark labeled “MMS,” decoded by the same dissector. Vendors often implement them with shared library code. And yet they solve completely different problems, and no project ever chooses between… Read More: ICCP vs IEC 61850: Two MMS Protocols, Two Jobs »
TASE.2 defines its functionality as operations and actions on objects, then maps each one onto an MMS service. That mapping is the Rosetta Stone of ICCP work: vendor documentation speaks TASE.2 (“Start Transfer”), the wire speaks MMS (“Write”), and moving between the two is half of every troubleshooting session. This reference lays out the complete map in both… Read More: ICCP Operations and Services: The Complete TASE.2 Map »
Every value an ICCP link carries is an instance of an object model from IEC 60870-6-802:2014. When two control centers negotiate a bilateral agreement, a large part of the technical work is agreeing, point by point, which of these models and which type variant each point uses — because the type determines exactly what crosses the wire: value… Read More: ICCP Object Models: Indication Points and Control Points »
Ask ten engineers what a dashboard is and you get ten answers. One means a Grafana page showing motor current. One means a trend client pulled from the historian. One means a Power BI report the plant manager opens on Monday. They are not the same product. They do not sit in the same place on the network.… Read More: Industrial Dashboard Software: 6 Tools Compared »
Ask ten engineers to name the most popular SCADA systems and you get ten different lists. That is not because anyone is wrong. It is because “popular” depends on which room you are standing in. Walk into an automotive plant and you will see FactoryTalk View SE on the wall. Walk into a distribution control center two kilometers… Read More: Most Popular SCADA Systems and Where Each One Fits »
SCADA as a Service promises lower infrastructure costs, automatic software updates, and easier scalability. But unlike enterprise software, utility control systems cannot simply move everything into the cloud. Real-time control, cybersecurity, regulatory compliance, and availability requirements make SCADA fundamentally different from a CRM or ERP platform. Software as a Service means the vendor runs the software in its… Read More: SCADA as a Service Explained: Cloud SCADA for Utilities »
A communication protocol is a set of rules and formats — both syntactic and semantic — that determines how two peer entities behave when they exchange data. Two devices that follow the same protocol can work together. Two devices that don’t follow the same protocol cannot communicate reliably, even if the physical connection is perfect. That definition sounds… Read More: What Is a Communication Protocol? Rules, Types, Examples »
Four vendors hold most of the ADMS market for large distribution utilities: Schneider Electric, Siemens, GE Vernova, and Hitachi Energy. On paper their datasheets read the same. Every one claims unified SCADA, DMS, and OMS, DER management, an open architecture, and IEC 62443 alignment. None of that is false. None of it helps you choose either. The real… Read More: ADMS Vendors: Schneider vs Siemens vs GE vs Hitachi »
An Advanced Distribution Management System is the software platform a utility uses to run its medium-voltage distribution network in real time. It watches the network, controls it, and reasons about it. That last part is what separates an ADMS from everything that came before it. A SCADA system tells you a breaker is open. An ADMS knows which… Read More: What Is an ADMS? Advanced Distribution Management System »
