SCADA does not “read the PLC.” It reads specific memory locations inside the PLC, over a network, using a protocol both sides agree on, on a schedule the SCADA engine controls. Every screen value, every alarm, every trend point comes from that one loop: ask, answer, map, display. Most explanations stop at a list of protocol names. That… Read More: How Does SCADA Communicate With a PLC? Explained Simply »
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 »
SCADA and ICS are not two names for the same thing. ICS (Industrial Control System) is the category. SCADA (Supervisory Control and Data Acquisition) is one type of system inside that category. Every SCADA system is an ICS. Not every ICS is a SCADA system. That’s the whole answer in three sentences. The rest of this article explains… Read More: SCADA and ICS: The Difference and How They Fit Together »
Every FTP client on this list is free. Not free trial. Not free with locked features. Free. So the question is not “which one costs nothing.” It’s “which one fits the work you do.” A tech pulling event records from relays needs a different tool than someone running nightly backup scripts. This guide sorts the clients by job,… Read More: Free FTP Clients: Which One Fits the Job You Do »
FTP is the oldest protocol you will still find running in a substation. It moves files between two machines over TCP. That is the whole job. But the way it does the job — two separate connections, plain-text commands, a server that calls you back — trips up more engineers than any other legacy protocol. This article walks… Read More: FTP Explained: How File Transfer Protocol Works »
