Four high-speed counting channels at 65 kHz sit inside a DIN-rail module smaller than your hand. No counter card, no expansion module, no extra cost — the fast inputs are on the CPU itself, waiting for an encoder, a flow meter, or a production line…

No internet. No router. No VPN. Just a SIM card and a number that calls you when the machine stops. For a certain class of industrial sites — remote, rural, or simply cheap — SMS is the most reliable alarm channel that exists, and the…

Three hundred meters of trench, a concrete saw, two weekends and a repair invoice for a cut cable — or a SIM card that costs less than lunch. The remote PLC question is rarely about technology. It is about what the cable is really going…

A building management system for a single HVAC plant room costs more than the plant room. That is the gap the big integrators quietly ignore — and the gap a compact PLC with BACnet support walks straight through. The BACnet-related content landed in the V6.2.x…

Ask five integrators what a micro PLC should be on a Modbus network, and four will say slave. The fifth — the one who has run out of CPU ports — knows the truth: the fifth one wants the PLC to be the master. xLogic…

Every PLC spec sheet says "0-10V analog inputs" and most buyers stop reading there. They should not. On the xLogic family the analog story runs deeper — PT100, PT1000, 0-20mA, 4-20mA, plus analog outputs in 0-10VDC and 0/4-20mA. That is a genuine temperture-and-instrumentation toolkit, not…

Sixteen expansion modules. Two hundred and eighty-two I/O points. On a CPU that fits in a shirt pocket. That is the claim, and after wiring one of these systems in a packaging retrofit, I can confirm the math holds — with one honest caveat about…

I have replaced more micro PLCs from wiring mistakes than from component failure. That is not an exaggeration — it is a career summary. The CPUs are not fragile. The wiring around them is. Here is the thing nobody prints on the datasheet: a 24VDC…

Let me start with a number: 214-219. That is the page range in the V6.2.2 manual where the floating-point blocks live. You would think the vendor buried them there becuase nobody uses them. Wrong. They buried them there because integer math is fine for ninety…

A 64-block CPU and a 1024-block CPU cost about the same to install. The difference is whether your project fits on the first try, or whether you spend a weekend deleting features you already promised the customer. Memory headroom is the quietest spec on the…

Here is a confession from an old hand: I learned control engineering on S7-200s, and I still think in SM bits. So when I found the xLadder editor using the same instruction family — SM special memory, ATCH/DTCH interrupts, CTU/CTD counters, SMB34 and SMB35 timed-interrupt…

Seventy, perhaps many more have been added. erhaps many more have been added.. That is the number of ready-made function blocks sitting inside xLogicSoft. Not seventy library add-ons you pay extra for — seventy blocks baked into the package, from simple on-delay timers to PID…

Commercial SCADA licences cost thousands and are overkill for a small panel. EasySCADA — the free, PC-based SCADA package from RIEVTECH — gives the xLogic family live screens, trends, alarms and data logging at zero licence cost. I have watched a pump station, a greenhouse…

The fastest way to test whether a programming tool is good is to hand it to someone who has never seen a PLC and time how long untill thier first working program. With xLogicSoft, that number has been under two hours every time I have…

One DIN-rail module speaking MQTT to the cloud, BACnet to the building, and Modbus TCP to the machines. That sentence used to describe a panel full of gateways. It now describes a single Ethernet-capable compact CPU, and the multi-protocol story on the xLogic platform is…
