Frequently asked questions
What is PLC programming?
PLC programming is the process of writing the control logic that runs on a programmable logic controller, defining how it reads sensor inputs, makes decisions, and drives outputs to motors, valves, and actuators on a machine or production line.
Which PLC brands do you support?
AutomatexLab supports Siemens, Allen-Bradley, Mitsubishi, Delta, Schneider Electric, Omron, ABB, and Beckhoff PLC platforms for projects across Pune and surrounding industrial areas.
Do you provide on-site commissioning?
Yes. AutomatexLab provides on-site commissioning across Pune, Pimpri-Chinchwad, Chakan, Talegaon, Bhosari MIDC, Ranjangaon MIDC, Hinjewadi, and Hadapsar, along with remote commissioning support where suitable.
Can you modify existing PLC programs?
Yes. AutomatexLab regularly modifies existing PLC programs to add new machine functions, fix logic issues, or support production changes, without disrupting the parts of the program that are working correctly.
Do you provide remote PLC support?
Yes. Many programming, troubleshooting, and optimization tasks can be handled remotely through secure, client-approved access to your PLC system, with your maintenance team present throughout the session.
How long does PLC development take?
A single machine program typically takes two to six weeks from requirement analysis to commissioning. Multi-machine systems or plant-wide projects can take longer depending on I/O count and integration scope.
Do you integrate SCADA and HMI?
Yes. PLC programs are commonly built alongside HMI screens and SCADA systems for operator control, alarm management, and production monitoring, and this integration is handled as part of the project.
Can you migrate old PLC systems?
Yes. AutomatexLab migrates legacy and end-of-life PLC platforms to current hardware, converting the existing logic, remapping I/O, and planning a cutover that minimizes production downtime.
Do you provide emergency support?
Yes. For unplanned downtime, AutomatexLab provides emergency troubleshooting support, remotely where possible, or on-site across Pune and nearby industrial areas when physical inspection is required.
Do you work outside Pune?
Yes. Alongside Pune and its industrial hubs, AutomatexLab supports projects in Nashik, Kolhapur, Aurangabad, and Satara, and provides remote PLC support to clients across India and internationally.

PLC programming, explained
In-depth answers for engineers and buyers researching PLC programming services in Pune before reaching out.
What is PLC programming?
PLC programming is the process of writing the control logic that runs on a programmable logic controller. It defines how the controller reads inputs from sensors and switches, applies decision logic, and drives outputs to motors, valves, and actuators, all within a scan cycle typically measured in milliseconds.
How PLC programming works
A PLC continuously runs a scan cycle. It reads the current state of all inputs, executes the program logic in sequence, updates outputs based on the results, then repeats. Programming defines what happens during that logic execution step, whether that is a simple ladder rung turning on a motor or a structured text block calculating a setpoint.
PLC vs DCS
A PLC is built for discrete and sequential machine control, executing logic quickly across a defined set of I/O. A DCS, or Distributed Control System, is built for large, continuous process plants where thousands of control loops need to be coordinated across a wide physical area. Manufacturing plants and machine automation typically use PLCs, while refineries and large chemical plants often use a DCS.
PLC vs relay logic
Relay logic uses physical electromechanical relays wired together to perform control functions, which makes changes difficult since every change requires rewiring. A PLC replaces that wiring with software logic, so the same control task can be modified, expanded, or corrected by editing the program instead of the panel, with far less downtime and far more flexibility.
PLC programming standards: IEC 61131-3
IEC 61131-3 is the international standard that defines the programming languages used across PLC platforms, including Ladder Logic, Function Block Diagram, Structured Text, and Sequential Function Chart. Following this standard keeps programs portable across different PLC brands and easier for other engineers to read and maintain.
Common PLC programming mistakes
The most frequent mistakes include unclear or missing tag naming, undocumented logic with no comments, monolithic programs that are not broken into logical sections, missing interlocks that allow unsafe machine states, and skipping simulation or FAT testing before commissioning. Each of these creates avoidable downtime once the machine is in production.
Signs your factory needs PLC upgrades
Common signs include a PLC platform that is officially end of life, spare parts becoming difficult to source, frequent unexplained faults tied to aging hardware, an inability to communicate with modern SCADA or IIoT systems, and a program so undocumented that no one on staff can safely modify it.
PLC commissioning checklist
A solid commissioning checklist covers verifying every I/O point against the wiring drawing, confirming safety circuits and interlocks function correctly, testing each machine sequence step by step, checking communication with HMI and SCADA systems, and validating alarm and fault handling before the line runs unattended.
How to choose the right PLC for your machine
Selecting a PLC starts with the I/O count your machine needs, plus spare capacity for future changes, the processing speed required for the application, whether motion or high-speed counting is involved, and the communication protocols your existing HMI or SCADA infrastructure already uses. Budget and long-term parts availability matter as much as the technical specification.
