Industrial automation and PLC upgrades for manufacturers and utilities

iiOTec is an industrial automation and controls engineering firm that designs and upgrades PLC-based control systems, remote monitoring solutions, and practical automation projects for manufacturers, utilities, and water and wastewater operators.

Why manufacturers use PLC upgrades and automation to cut downtime and quality losses:

Downtime and quality issues quietly drain profit, cut efficiency, and pile stress on your team. Studies show the average manufacturing plant loses hundreds of production hours each year to unplanned stops and labor or quality failures. We design and implement automation, PLC upgrades, and control systems that reduce those losses and keep your lines running.

What is our Automation as a Service (A³S) model?

Questions?

Our A³S model helps small and midsize manufacturers upgrade PLCs and automation by using a subscription-style plan instead of a large upfront capital project. We offer customizable PLC upgrades and automation equipment leasing, including cabinet with HMI as a base.

Our three‑year agreement starts at a $2,977 initial payment and $577 monthly. This includes the control panel, full SCADA access, remote monitoring, performance reporting, and ongoing technical support and troubleshooting.

PLC Upgrades

How do we approach industrial automation projects?

  • We design PLC and automation projects that go beyond quick fixes to reduce risk and support ROI.

  • We lead automation initiatives for manufacturers with limited engineering staff.

  • We deliver practical upgrades—PLCs, control panels, machine vision, and IIoT—to improve KPIs, cut costs, and reduce daily stress.

  • We work best as a trusted extension of your manufacturing team.

  • A “your ideas, our implementation” approach—turning your process knowledge into reliable, production‑ready automation.

Key areas where we help manufacturers:

iiOT – Industrial IoT data from your machines

We connect shop‑floor equipment, sensors, and PLCs so you can see real‑time production data at your desk or mobile device and make faster, better decisions.

Modernization

Outdated control systems that are a pain to keep running are our specialty. Invite us in for an assessment to explore PLC and controls upgrades that increase uptime, shorten cycle times, and reduce firefighting on the plant floor.
ASSESSMENT

Machine Vision

Improving quality and reducing scrap by detecting out‑of‑tolerance product and stopping production before bad parts pile up.

Visualization and SCADA

Giving operators and supervisors real‑time dashboards, graphs, and reports so they can act on issues quickly and improve performance over time.
SCADA/IOT

Desalination & Pump Systems

Since 2006, our desalination projects have translated directly to other pumping operations, improving control and efficiency so you can reduce energy use and operating costs over the long term.

Assessments

You know automation can help—but what kind, and where are the best paybacks? Our Optimization Assessment identifies high‑ROI opportunities on your factory floor so you can prioritize the projects that matter most.
