Authorized Siemens Partner · Chennai, Tamil Nadu

Siemens PLC Dealer in Chennai —
SIMATIC S7-1200, S7-1500 &
TIA Portal Specialists

When a Chennai plant engineer specifies a Siemens SIMATIC controller, they need more than a box off a shelf — they need TIA Portal expertise, PROFINET commissioning know-how, and a local team who can be on-site the same day a fault occurs. That is exactly what Innovative Instruments and Controls (IIC) delivers.

IIC is a Siemens-authorized PLC dealer in Chennai with a resident engineering team fluent in the full SIMATIC portfolio — from the entry-level S7-1200 used in water treatment panels to the S7-1500H redundant CPUs running continuous chemical plants. Every unit we supply is sourced through the official Siemens distribution channel, carries a manufacturer warranty, and is backed by our own after-sales commitment.

Common Questions

Frequently Asked
Questions

Have questions about sourcing Siemens PLCs and HMIs in Chennai? Find answers to the most common queries below.

Ask Us Directly
Yes. Because we source all PLCs and system parts directly through official, authorized Siemens distribution channels in India, every single central CPU and module carries the official Siemens manufacturer warranty. We have a strict policy against grey-market items, paralell imports of unvouched material, or refurbished hardware.
Since we maintain a ready physical stock of key S7-1200 central processors (from CPU 1211C through to CPU 1217C), standard S7-1500 units, expansion Signal Modules (SMs), Communication Modules (CMs), and ET 200SP remote I/O configurations, we can arrange same-day or next-day on-site delivery directly to plants in Guindy, Ambattur, Sriperumbudur, Oragadam, Manali, and other Chennai hubs. Non-stock custom parts are sourced and delivered within 5 to 7 working days.
Every engineer on our team is a resident, in-house technical expert. We do not subcontract any core logic programming, interface design, or site commissioning. Our developers are deeply trained on the Totally Integrated Automation (TIA) Portal. They write structured logic, draft high-resolution widescreen SIMATIC panels, map OPC UA channels, configure safety programs on S7-1500F CPUs, and interface with drives seamlessly.
Yes. While we are Siemens-centric, a key differentiator is our multi-brand project capability. If a client budget or existing specification demands it, we regularly select, design, wire, and commission full panels containing Siemens SIMATIC controllers linked directly to external drive systems, such as Delta, Schneider, or Mitsubishi VFDs.
Under our written and legally binding Service Level Agreements (SLAs)—which we stand behind instead of simple verbal promises—we offer a guaranteed 4-hour on-site physical breakdown response time for plants located anywhere inside Chennai city and neighboring industrial zones (such as Sriperumbudur and Oragadam). For other districts of Tamil Nadu, we guarantee an on-site physical response within 24 hours.
We specialize in legacy migrations with minimal production disruption. We audit and map out classic STEP 7 program structures to TIA Portal formats, replace old keypad HMIs with sleek touch screens, and upgrade WinCC version 7 SCADA systems to current Professional tiers. During SCADA transitions, we map and migrate historical SQL log databases seamlessly to prevent data loss.
