PLC AUTOMATION ENGINEERING
PLC Programming for Industrial Automation.
SAAVI provides PLC programming and control engineering for automated machines, production stations and integrated manufacturing systems in Pune and Maharashtra. We work across PLC logic, HMI integration, machine sequencing, safety, drives, communication, commissioning and troubleshooting.

01 / PLC ENGINEERING
Control logic designed around the machine process.
A reliable PLC program starts with the machine sequence, safety requirements, operator interaction and process conditions — not just individual inputs and outputs.
SAAVI develops structured control logic for machine automation, assembly stations, testing equipment, material handling and production systems. Our engineering approach connects PLC logic with HMI screens, sensors, drives, robots, cameras and peripheral devices where the application requires it.
WHAT WE COVER
PLC & control engineering
- Automatic and manual operating sequences
- Machine interlocks, permissives and alarms
- Safety-related control logic and fault handling
- HMI commands, status, diagnostics and recipes
- Servo, VFD and motion-control coordination
- Industrial communication and device integration
- Commissioning, debugging and production support
02 / PLC CAPABILITIES
From I/O logic to complete machine control.
The PLC is the control layer of the machine. We structure the program so that sequences, faults, manual operations and production states can be understood and maintained during commissioning and future service.
HMI integration
Operator controls, machine status, alarms, diagnostics, counters, recipes and production information.
Interlocks & safety
Permissives, safety conditions, fault states, reset logic and controlled recovery from abnormal conditions.
Drives & motion
PLC coordination with VFDs, servo systems, positioning, homing and application-specific motion sequences.
Device integration
Communication between PLCs and industrial devices such as scanners, cameras, testers, robots and peripheral equipment.
Commissioning support
Online troubleshooting, sequence debugging, I/O verification, production trials and machine handover support.
03 / PLC PLATFORMS
Industrial PLC platforms and machine integration.
SAAVI's automation work includes Siemens and Mitsubishi PLC platforms, with control architecture selected according to the machine, communication requirements and customer standard.
S7-1200 / S7-1500
PLC programming, sequence control, HMI integration, industrial communication and commissioning for machine automation.
FX Series & control
PLC logic, machine sequencing, device communication and integration for automation stations and equipment.
PLC + HMI + Devices
Control logic connected with drives, robots, vision systems, testers, sensors, scanners and production data.
04 / ENGINEERING PROCESS
Structured PLC development from requirement to commissioning.
The exact workflow depends on the machine and customer standard, but the engineering normally follows a clear path from process understanding through production validation.
01
Understand the process
Review sequence, I/O, cycle requirements, operator actions, safety and quality conditions.
02
Build the control logic
Develop automatic/manual modes, interlocks, alarms, state handling and device commands.
03
Integrate & debug
Connect HMI, drives, sensors, robots, vision and other devices and verify machine behavior.
04
Commission & hand over
Run dry cycles and production trials, resolve faults and support final machine validation.
05 / APPLICATIONS
PLC programming for real manufacturing applications.
PLC control can sit at the center of many machine and station architectures. Typical applications include:
Assembly & pressing stations
Sequence control for part presence, clamping, feeders, pressing, verification and cycle completion.
Testing machines
Multi-step test sequences, tester communication, pass/fail handling, rejection and reset logic.
Vision inspection
Trigger, result handling and machine decision logic for camera-based inspection and identification.
Traceability systems
Part identification, station status, result capture and production data exchange.
Robot & gantry cells
Handshakes, ready/busy/fault states, target positions and coordinated machine sequences.
PLC modernization
Controls upgrades, logic restructuring, HMI improvements, communication and machine debugging.
06 / FAQ
PLC programming questions.
Do you provide PLC programming for new machines?
Yes. PLC engineering can be part of a new machine or automation station, including sequence logic, HMI, interlocks, device communication and commissioning.
Can you work with existing PLC programs?
Yes. Existing-machine debugging, logic modifications, HMI improvements, communication changes and PLC modernization can be handled based on the available project and machine information.
Which PLC platforms do you work with?
SAAVI's documented automation capabilities include Siemens and Mitsubishi PLC platforms. The exact PLC and software version can be selected according to the project requirement and customer standard.
Do you provide commissioning and troubleshooting?
Yes. Commissioning support can include I/O checks, sequence debugging, device handshakes, fault diagnosis, production trials and final validation.
