PLC TROUBLESHOOTING

PLC Down? We Find the Fault Fast.
Before They Fail

CPU stop, I/O errors, logic faults and network loss — structured diagnosis for Siemens, Allen-Bradley, Mitsubishi, Delta and more. On-site or remote support to get your controller online again.

HMI / TOUCH DISPLAY TROUBLESHOOTING

Blank screen, Dead touch, Fixed.
Fewer surprises.

HMI not responding, lost PLC link, corrupted project or weak backlight — we diagnose display, touch, power and communication so operators can control the machine again with confidence.

VFD & SERVO TROUBLESHOOTING

Drive tripped, Axis stopped, We clear it.
Before They Fail

VFD overcurrent, overvoltage, overheating and servo encoder or position alarms — root-cause checks on power, motor, feedback and parameters so pumps, fans, conveyors and motion axes run stable again.

How It Works

Simple Maintenance Process

1

Scope & Schedule

We agree equipment list, frequency and preferred visit windows.

2

On-Site Visit

Inspection, cleaning, measurements and parameter backup on site.

3

Findings

Clear report of condition, risks and recommended actions.

4

Follow-Up

Support for any urgent fixes and planning for the next cycle.

Why Preventive Maintenance

Stop failures before they stop production

Higher uptime

Catch overheating, weak capacitors and loose connections before they trip the line.

Lower lifetime cost

Planned care costs less than emergency repair and lost production.

Parameter security

Regular backups mean faster recovery if a unit ever needs replacement.

Clear documentation

Every visit ends with a written condition report for your records.

FAQ

Frequently Asked Questions

PLC, HMI, VFD and servo drives — plus related I/O, power supplies and industrial networks (Modbus, Profibus, Profinet, Ethernet/IP).

Yes for critical production lines, subject to location and technician availability. Call or WhatsApp for priority response.

Yes. With VPN or remote access we can often diagnose logic, parameters and communication faults without a site visit. Hardware faults still need on-site work.

Equipment brand/model, exact fault code or message, when it started, any recent power events or changes, and whether the machine can run in a limited mode.

Yes. We support sites across Bangladesh. Response time depends on location; remote diagnosis is available first where useful.

We verify operation, recommend any follow-up (e.g. maintenance or spare), and can back up parameters/programs for faster recovery next time.
