Key Takeaways
- The Rtelligent RM500 EtherCAT motion controller suits multi-axis machines built by Bengaluru integrators.
- As an authorised Schneider Electric partner we also supply Modicon controllers, HMIs and Citect SCADA.
- Choose by I/O count, motion axes, communication, process or machine duty and expansion plans.
- We build PLC control panels and supply the drives and sensors around the controller, all from Ahmedabad.
Bengaluru's control engineers face a wide spread of jobs. A robotics integrator in Whitefield needs synchronised EtherCAT motion, an SPM builder in Peenya wants a compact PLC that can pulse a few servo axes, a component plant at Bidadi standardises on one platform across its lines, and a process unit near Doddaballapur needs analogue loops and SCADA. As a PLC supplier in Bengaluru, RB Automation dispatches Modicon and Rtelligent controllers out of Ahmedabad and talks you through the platform choice by phone, WhatsApp and email.
Controllers We Supply to Bengaluru
Rtelligent motion-focused PLCs
- RM500/510 PLC and motion controller: EtherCAT master programmed in CODESYS 3.5, with RS-485, Ethernet and CANopen ports and up to 16 inputs and 16 outputs. Ideal for multi-axis machines with EtherCAT servo and stepper drives.
- RX8U small PLC: 8-axis pulse output, 16 inputs and 16 transistor outputs, expandable with up to 8 RE I/O modules, FX3U-compatible instructions.
- RX3U pulse-type small PLC for compact machines running steppers or servos by pulse.
- Card-type remote I/O and the REC1 EtherCAT coupler to place I/O close to the machine.
Schneider Electric
RB Automation is an authorised Schneider Electric partner. We supply Modicon machine controllers, motion controllers, M340 process controllers with up to 1024 discrete and 256 analogue I/O, and distributed I/O, plus Harmony GTO and ET6 HMIs and Citect SCADA. The Schneider Electric PLC category has the details.
Controller and screen in one housing
Both the MX3G-43C-22MT and the larger MX3G-70C-48MT pair FX3S-compatible logic with a touch display and 300 kHz high-speed pulse output, which saves a panel cut-out and a cable on small machines and benchtop equipment. The combo unit page compares them.
Six Points for PLC Selection
- I/O: list every switch, valve, sensor and transmitter today, then leave headroom for later.
- Motion: pulse outputs cover a few axes; EtherCAT suits many synchronised axes.
- Networks: match Modbus, Ethernet, CANopen or EtherCAT to the drives, HMIs and SCADA on site.
- Duty: a machine wants quick scans and coordinated axes; a process skid wants PID loops, alarms and history.
- Platform policy: a single family across a site keeps spares, software licences and skills simple.
- Growth: remote I/O and couplers add points without reworking the main panel.

PLC Applications Across Bengaluru
Robotics and multi-axis machines
Integrators in Whitefield and Electronic City use the RM500 as an EtherCAT master for R6 servo drives and ECT60 or EST60X2 stepper drives, with remote I/O on the REC1 coupler.
Machine tools and SPMs
Builders in Peenya, Bommasandra and Jigani use pulse-type PLCs such as the RX8U or a PLC-HMI combo for loaders, test fixtures and special purpose stations.
Automotive plants
Plants at Bidadi, Narasapura, Hoskote and Attibele often standardise on a networked platform with distributed I/O across conveyors and assembly lines.
Process and utilities
Units around Harohalli, Doddaballapur and Dobbaspet run pumps, tanks and dosing with analogue inputs from pressure and level transmitters, often with SCADA for logging.
Ready-Built Panels
If you would rather receive a wired cabinet than loose parts, RB Automation builds custom PLC control panels, complete with the drives, operator screens and field sensors they connect to. Two related Bengaluru guides cover VFD selection and servo drive selection.
Controller Options Compared
| Controller | Brand | Strength | Typical Bengaluru use |
|---|---|---|---|
| RM500/510 | Rtelligent | EtherCAT master, CODESYS 3.5 | Robot cells and multi-axis gantries |
| RX8U | Rtelligent | 8-axis pulse output, expandable I/O | SPMs and test fixtures |
| RX3U | Rtelligent | Pulse-type small PLC | Compact stepper or servo machines |
| MX3G PLC-HMI combo | PLC-HMI combo | PLC and touch screen in one | Benchtop and small machines |
| Modicon machine controllers | Schneider Electric | Platform standardisation | Automotive and OEM lines |
| Modicon M340 process controller | Schneider Electric | Up to 1024 discrete, 256 analogue I/O | Process and utility plants |
Machine Control vs Process Control
| Aspect | Machine control | Process control |
|---|---|---|
| Typical signals | Switches, valves, pulses, EtherCAT | 4-20 mA transmitters feeding PID loops |
| What matters | Scan speed, motion, synchronisation | Stability, alarms, trends and logging |
| Usual companions | Servo and stepper drives, HMI | VFDs, transmitters, SCADA |
A Typical PLC Application in Bengaluru
Take a typical end-of-line test machine of the kind built for automotive component plants around Bidadi and Narasapura. The part is clamped, a servo press checks a fit, two stepper axes position a measuring probe, a pressure transmitter verifies a leak test and a label printer marks the result. An RM500 can run the servo and stepper axes over EtherCAT, read the transmitter through an analogue module, and log each result to the plant network over Ethernet. For a much simpler machine, such as a fixture that clamps, presses and ejects, an RX8U or a PLC-HMI combo is usually enough. The choice follows the number of axes and the data the plant expects.
Where PLC Choices Go Wrong
- Sizing I/O to the current drawing with no room for the inevitable extra sensor.
- Discovering after ordering that the CPU cannot pulse all the planned axes.
- Forgetting which bus the existing drives and screens already use.
- Letting every new line bring its own controller make, so spares and training multiply.
Your PLC Enquiry Checklist
- How many digital and analogue points
- How many axes, and which drives
- Which networks: Modbus, Ethernet, CANopen or EtherCAT
- Whether an operator screen or SCADA is needed
- Brand preference, whether you want a built panel, and how many systems
Why Choose RB Automation as Your PLC Supplier
Our two partnerships, authorised partner of Schneider Electric and technical partner of Rtelligent, mean the advice is not tied to one catalogue: Modicon where a site has already committed to it, Rtelligent where multi-axis motion and budget lead the decision. Controllers and panels are dispatched from Ahmedabad, and selection support is remote: call +91 8511104864, WhatsApp +91 9898739737 or email contact@rbautomate.com, Monday to Saturday, 10:00 am to 6:00 pm. See every product family on the Bengaluru supplier page.
Conclusion
From EtherCAT robot cells in Whitefield to process skids near Doddaballapur, the controller choice follows the points to be wired, the axes to be moved, the networks already in place and the platform your plant prefers. Describe your project to RB Automation and we will propose a Modicon or Rtelligent controller to suit it.
