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?
Siemens, Mitsubishi, Allen-Bradley, Schneider Electric, Omron, Delta, Beckhoff, and ABB.
Can you modify existing PLC programs?
Yes. Existing PLC programs are modified to add new machine functions, fix logic issues, or support production changes without disrupting the parts of the program that already work correctly.
Do you provide remote support?
Yes. Many programming, troubleshooting, and optimization tasks are handled remotely through secure, client-approved access.
How much does PLC programming cost?
Cost depends on I/O count, logic complexity, PLC brand, and whether HMI or SCADA integration is included. A fixed quote is provided after reviewing project requirements.
How long does development take?
A single machine program typically takes two to six weeks from requirement analysis to commissioning. Multi-machine or plant-wide systems can take longer.
Can you migrate old PLCs?
Yes. Legacy and end-of-life PLC platforms are migrated to current hardware, with logic conversion, I/O remapping, and a planned cutover.
Do you provide FAT and SAT?
Yes, included in every PLC programming project to validate the system before and after it goes live.
Can you integrate SCADA?
Yes. PLC systems are integrated with SCADA platforms for plant-wide monitoring, historical data logging, alarm management, and reporting.
Do you work internationally?
Yes. AutomatexLab supports PAN India projects on-site and provides remote PLC programming and support internationally.
Do you provide PLC backup and restore?
Yes. Lost or outdated PLC backups are recovered where possible, and a clean, current backup is archived for your team going forward.
Can you help with servo synchronization issues?
Yes. Servo and motion control synchronization problems are a common part of the PLC troubleshooting and optimization work AutomatexLab handles.
Do you provide documentation after the project?
Yes. Every project is delivered with I/O lists, logic descriptions, and program backups.
Can you support system integrators and panel builders directly?
Yes. AutomatexLab regularly works alongside system integrators and panel builders as the PLC programming partner on a larger project.
Do you sign NDAs for industrial projects?
Yes, before reviewing proprietary machine designs, drawings, or existing PLC programs.
Need an experienced PLC programmer?
Whether you’re automating a new machine, upgrading an existing PLC, or troubleshooting production downtime, AutomatexLab’s engineers can help with development, commissioning, migration, and optimization.
