Common Questions

Frequently Asked Questions

Answers to the questions we hear most often about our BIM Services.

We provide fundamental industrial automation design services, focusing on basic PLC programming using Ladder Logic, custom HMI operator screen designing, I/O mapping and basic machine sequence control.
We primarily develop PLC code using standard Ladder Logic (Ladder Diagram - LD), which is universally accepted, easy to read and convenient for shop-floor technicians to maintain.
Features varies from model to model. Its mainly depends on clients requirements how and what representation they want on screen, typically A/M operation control, machine status displays, buttons controls and visual alarm message popups are given.
We require the Control Philosophy of operation, physical I/O list (sensors, motors, valves) and preferred PLC/HMI software brand.
Yes. We review existing relay schematics or hardwired control panels, convert the relay logic into clean PLC ladder code.
