ControlByWeb offers a range of flexible and feature-rich micro PLCs, or programmable logic controllers. ControlByWeb PLCs provide all the benefits of micro PLCs while offering additional advantages and capabilities for the Industrial Internet of Things (IIoT).
Built-In Firmware
ControlByWeb PLCs feature a lightweight, easy-to-use interface. Building custom logic is as easy as navigating drop-down menus.
Data Logging
Save edge data logs to a separate computer or server. Program your micro PLC to send log data via email or FTP.
Peer-to-Peer Networking
P2P networking is available between ControlByWeb relays, allowing for shared I/O and remote inputs and relay control.
Inherently Secure
ControlByWeb devices have no native OS or file system, making them less prone to vulnerabilities.
Expansive Communication Protocols
ControlByWeb PLCs support HTTP GET, MQTT, XML, JSON, SNMP, Modbus, and TCP/IP.
ControlByWeb Cloud
400 Series devices and WiFi PLCs can utilize the ControlByWeb Cloud to remotely monitor and manage multiple locations.

Application Spotlight: Greenhouse
With expandable I/O, on-board logic, and easy integration, micro PLCs are a great fit for IIoT applications like greenhouse monitoring and control.
Greenhouse automation systems are increasingly reliant on automation systems. With the growing demand for food, house plants, and cannabis, commercial greenhouses are turning to automation to improve quality and production. Reliable monitoring and control systems that can scale from small to large greenhouse structures are necessary. Features such as temperature, humidity, and soil moisture sensors, along with the ability to control fans, vents, and heaters, are essential for effective greenhouse automation.
Popular relays, like the ControlByWeb X-410™, simplify industrial applications like greenhouse automation without the need for coding.
Programming a PLC is typically a specialized task requiring a skilled engineer who isn’t always available. Even so-called “easy-to-use” PLCs on the market require Ladder Logic, Function Block, or some kind of diagram building with complex code, scripts, and a mountain of settings. On top of all that, most PLC user interfaces are overloaded with options, menus, sub-menus, wizards, modals, etc.
Our no-code PLCs use a very simple user interface with an uncomplicated, single menu system on the left-hand side. Most users will simply start at the top section and fill in the fields as they move down.
Programming logic is one of the simplest tasks for our users. Choose between scheduled or conditional tasks and use drop-down menus to select options. These options are very straightforward, including turning relays on and off, sending email alerts, or logging a change under specific conditions.

A micro PLC is a compact version of a programmable logic controller (PLC) with a smaller memory capacity and embedded input and outputs (I/O). It’s designed to control small machinery and processes, similar to full-size PLCs but on a smaller scale. Learn about the differences in this micro PLC article.
How do you program micro PLCs? Is the process different compared to a standard PLC?
Micro PLCs are programmed used dedicated software and by writing logical code, similar to a standard PLC. Ladder logic and function block are popular, albeit complex and specialized, coding languages. All ControlByWeb PLCs are programmed using a simple, embedded user interface with straightforward menus and selections. No code is required to create logic.
What communication protocols do micro PLCs use?
Micro PLCs commonly use standard industrial protocols like Modbus RTU and TCP, SNMP, MQTT, and proprietary protocols specific to the PLC manufacturer. They can communicate with personal computers, operator interfaces, other PLCs, and more through various networks and protocols. The ControlByWeb products page allows filtering by protocol to ensure compatibility.
Why choose a micro PLC over a standard PLC?
Micro PLCs are chosen over standard PLCs for their cost-effectiveness, compact size, and sufficient functionality for small-scale IIoT applications. They offer fast program scan times, similar communication protocols as larger PLCs, and easier integration into space-constrained environments. They can be a more practical choice for applications that don’t require the extensive I/O and memory capacity of standard or highly specialized PLCs.
