Frequently Asked Questions (FAQ)

Resolve your queries from the below FAQ's related to Programmable Logic Controllers Manufacturer & Supplier in India.
What is a Programmable Logic Controller?
A PLC is an industrial grade digital computer designed to automate electromechanical processes. Unlike a standard PC, it is built for high reliability and ease of programming in factory settings. It monitors inputs from sensors, makes decisions based on a custom program, and controls output devices like motors or valves.
What are the most common programming languages for PLCs?

The international standard IEC 61131-3 defines five languages:

  • Ladder Diagram (LD): The most popular, resembling electrical relay logic.

  • Function Block Diagram (FBD): Uses graphical blocks for functions.

  • Structured Text (ST): A high-level, text-based language similar to Pascal.

  • Sequential Function Chart (SFC): Best for step-by-step processes.

  • Instruction List (IL): A low-level, assembly-like language.

What is the difference between Fixed and Modular PLCs?
Fixed PLCs (also called compact or brick PLCs) have the CPU, power supply, and I/O ports built into one single enclosure. They are cost-effective for small tasks. Modular PLCs consist of a rack or chassis where you can plug in different modules. This allows for easy expansion and customization for large-scale operations.
How does the PLC scan cycle work?

The controller operates in a continuous loop called a scan cycle. It follows three main steps:

  1. Input Scan: It checks the status of all connected input devices.

  2. Program Scan: It runs the user logic based on those input states.

  3. Output Update: It adjusts the output devices according to the logic results. After completing these, it performs internal diagnostics and repeats the cycle, often in milliseconds.

What is a Human Machine Interface or HMI?
An HMI is a screen or dashboard that connects a human operator to the PLC. It provides a visual representation of the machine status, allows operators to change setpoints, and displays alarms or performance data in real time.
How do PLCs communicate with other devices?

Modern PLCs use various communication protocols to talk to other controllers, HMIs, or office networks. Common protocols include:

  • EtherNet/IP

  • Modbus

  • Profibus

  • Profinet

Why are PLCs better than traditional relay logic?

Before PLCs, factories used hundreds of physical hard-wired relays. PLCs offer:

  • Flexibility: Changing a process only requires a software update, not physical rewiring.

  • Reliability: Fewer moving parts mean less wear and tear.

  • Space Savings: One small controller replaces entire cabinets of relays.

  • Diagnostics: Software makes it easier to find and fix faults.

What is the difference between Digital and Analog I/O?
Digital (Discrete) I/O handles signals with only two states, such as On or Off. Examples include push buttons and limit switches. Analog I/O deals with continuous ranges, like temperature (0 to 100 degrees) or pressure, typically converted into voltage (0 to 10V) or current (4 to 20mA) signals.
What are the primary components of a PLC system?

A standard PLC setup includes four essential parts:

  • Central Processing Unit (CPU): The brain that executes program logic.

  • Input/Output (I/O) Modules: Interfaces that connect the controller to external sensors and actuators.

  • Power Supply: Converts line voltage to the low DC voltage required by the electronics.

  • Programming Device: A computer or handheld unit used to load the control logic.

What is a Watchdog Timer?
A watchdog timer is a safety feature that monitors the scan cycle. If the program gets stuck or takes too long to complete a scan, the watchdog timer will trip, usually shutting down the system to prevent unpredictable or dangerous behavior.
