Industrial IoT Solutions in India for Factories, Plants & Utilities

Industrial IoT is IoT applied to plants and factories. The idea is the same, connected devices sending data to software, but the equipment is built for a harder job: sealed enclosures, wide temperature ratings, long battery life, and industrial interfaces such as RS485 Modbus and 4–20 mA so it can read the meters, PLCs and instruments already on site.

They are related, not the same. Industry 4.0 is the idea of a plant whose machines, utilities and stores report their own condition, and a smart factory is a plant that has got there. Industrial IoT is the means: the sensors, converters and networks that collect the data. Most plants start smaller than the phrase suggests, by connecting the equipment they already have and getting one reliable set of readings.

Yes. SCADA is the operator's view and history of what the PLCs control, and it stays. Wireless IoT adds the points SCADA never had, such as the sub-meters, the DG tank, the cold room and the boundary noise meter, because nobody ran a cable to them. The readings land in SCADA over Modbus TCP, MQTT or your historian, or in a separate dashboard if the SCADA team prefers to keep the plant network untouched.

No. A LoRaWAN gateway moves radio packets to a network server; it does not control anything. The PLC keeps every control loop, interlock and emergency stop. Macnman converters read what the PLC and the meters already expose over Modbus or 4–20 mA, and MacSet controllers switch pumps, valves and alarms on schedules and thresholds for jobs the PLC was never wired to.

Both, at different ends. Modbus RTU is how the meter, drive or PLC speaks on the RS485 line in the panel; MQTT is how the reading reaches your broker, SCADA or cloud. A MacSync converter reads Modbus registers in the field and sends them over LoRaWAN to a network server, or publishes them directly as MQTT over Wi-Fi or 4G. Nothing in the panel has to change.

Yes, and this is how most plants start. If the equipment has an RS485 Modbus port or a 4–20 mA or 0–10 V output, a MacSync converter reads it and sends the values over LoRaWAN, Wi-Fi or 4G. The machine, its controller and its wiring stay as they are. Where there is no usable output, a wireless sensor is added beside the equipment instead.

Usually neither. A converter is wired to a spare RS485 port or in parallel with an existing 4–20 mA signal and only reads, so the PLC program is not touched. Non-contact and surface-mounted sensors go in while the process runs. A sensor that sits inside a tank or a pipeline is the exception and is normally fitted at a planned stop.

Wire the loop into a MacSync analog converter. It reads the 4–20 mA current at 12-bit resolution on two channels, can supply the loop power for a two-wire transmitter, and sends the value over LoRaWAN, or over Wi-Fi as MQTT, on the interval you set. The scaling from milliamps to engineering units is done in the decoder or on your platform, so the transmitter keeps its existing range.

It depends on distance and data. LoRaWAN suits many battery-powered points spread over a large site, because one gateway covers a plant and there is no per-device fee. Wi-Fi suits indoor points inside reliable coverage that need to send more data, more often. 4G suits a single remote asset with no local network. Most plants use more than one, and Macnman builds the same converters and controllers for all three.

An outdoor MacLink Gen 2 gateway typically covers 2 to 5 km in built-up areas, and an indoor Setu X1 gateway 1 to 2 km. Steel structures, basements and thick walls reduce that, which is why a coverage check comes before an order. Each gateway has eight channels and supports more than 2,000 devices, so capacity is rarely the limit in a single plant.

Through walls and across a plant, yes; through heavy steel and deep basements, with planning. Concrete and steel cut the range, so a gateway placed high and central usually covers a plant, and a second gateway or an indoor Setu X1 covers a basement or a utility block. A coverage check with a device at the real mounting point comes before an order; the network calculator and the placement guide on this site are the starting point.

LoRaWAN sensors and converters run on a 19 Ah lithium cell. The years depend on the reporting interval, the spreading factor and the temperature: for the MacSync LX1 the estimate is about 8 years at one reading an hour on SF7, and about 4 years at a reading every 5 minutes. Wi-Fi costs more energy per message: the MacSync WX1 converter is estimated at about 2.5 years on 15-minute uploads and 6.7 years on hourly uploads. Controllers and gateways run from mains or DC. The battery life calculators on this site give the figure for your settings.

No. A LoRaWAN network server and an MQTT broker can both run on a machine inside the plant, so the data never has to leave the site. Macnman devices do not require a subscription to work. A cloud platform is an option for multi-site visibility, not a condition of using the hardware.

You own it. The LoRaWAN network server can be ChirpStack running on the MacLink or Setu gateway or on a machine inside the plant, and the MQTT broker can sit beside it, so readings never leave the site unless you send them out. The payload formats are published, and there is no Macnman account or subscription in the path.

LoRaWAN is its own radio network with its own gateway; the devices never join the plant Ethernet or the PLC network, and the converters only read from the RS485 line or the 4–20 mA loop. The gateway's backhaul to your server can run on a separate VLAN, and the Wi-Fi devices on an SSID you control. Writes to a register or a relay happen only where you configure them, from your platform.

Yes. The devices deliver data over open protocols: LoRaWAN to any standard network server, and MQTT or HTTPS from the Wi-Fi and 4G devices. Most SCADA, MES and analytics platforms accept one of these directly or through their own connector. Send us the name of the platform and we will confirm the route.

Yes. The devices are standard LoRaWAN, so they register on ChirpStack, The Things Stack, LORIOT, Orbiwise or a private network server, with payload decoders published on GitHub for the main sensors and converters. From the network server, or directly from the Wi-Fi and 4G devices, the data reaches AWS IoT Core, Azure IoT Hub or your own broker over MQTT or HTTPS.

For monitoring and supervisory control, yes. Readings are sent on a schedule, converters store data on board and forward it after an outage, and controllers run their rules locally. Wireless should not carry safety interlocks, emergency shutdown or fast closed-loop control. Those stay wired.

Every LoRaWAN device joins with its own keys and encrypts its payload with AES-128; the network server checks every frame, so a captured packet cannot be replayed. Like any radio, the band can be jammed by a strong transmitter nearby, which is why LoRaWAN is used for monitoring, alarms and supervisory switching, and why safety interlocks stay wired. A missed heartbeat is itself an alarm on the platform.

Yes, if each machine or feeder has a Modbus energy meter, which most panels already do or can have added. A MacSync converter polls the meters on one RS485 line and reports kWh, demand, voltage, current and power factor per meter. That shows which line, shift or machine uses the energy, which a single incomer meter cannot.

Yes. A LoRaWAN capacitive fuel level sensor in the day tank or bulk tank reports the diesel level continuously to ±1% of full scale. Refills, consumption and sudden drops all show in the trend, and a low-level alert can be raised before the tank runs dry. Generator controllers with a Modbus port can also be read through a MacSync converter.

Temperature-based condition monitoring is covered directly: PT100 probes through the RTD sensor, and non-contact infrared for hot or moving surfaces. For vibration, a transmitter with a Modbus or 4–20 mA output connects through a MacSync converter and its values travel over the same network. Tell us the machines and we will suggest the measurement points.

The standard devices are industrial, IP65 with an IP67 option, and are not certified for use in hazardous (Ex) zones. Tell us the zone classification before ordering and we will confirm what can be used and where it can be mounted.

Yes. LoRaWAN in India uses the IN865 plan in the 865 to 867 MHz band, which the Wireless Planning and Coordination wing (WPC) has delicensed for low-power devices, so you need no spectrum licence to run your own gateway. Macnman hardware is built for IN865 and is WPC compliant. For other countries the devices come in EU868, US915, AU915 and RU864 variants, with KR920 and AS923 on selected products; the band is fixed by the country's regulations, so tell us where the devices will be installed.

Yes. As the manufacturer, Macnman adapts firmware, payload formats, enclosures and branding for OEM and project orders. Customisation depends on volume, so share the quantity and the change you need and we will tell you what is possible.

Four lines, and the device is only one of them: the number of points and the signal type at each, the gateways needed for coverage (one usually covers a plant, basements and far blocks add more), the mounting and wiring at each point, and the platform the data lands in, which is often one you already run. Send the point list with signal types and a site plan and we quote the whole project rather than a device in isolation.

Yes. Macnman Technologies designs and manufactures its sensors, converters, controllers and gateways in Pune, Maharashtra, and supports them directly from the engineering team.

Check six things: open protocols rather than a proprietary radio; IN865 and WPC compliance stated on the datasheet; specifications and decoders published, not shared on request; a pilot on the same hardware that will scale; engineers in India who designed the device; and data that stays on your servers with no subscription. A manufacturer can show all six; a reseller or a platform company usually cannot.

LoRaWAN devices are built in regional band variants: IN865 for India, EU868 for Europe and the countries that follow the European plan, plus US915, AU915 and RU864. The Wi-Fi and 4G devices do not depend on a LoRaWAN band. Radio approvals differ by country: the hardware is WPC approved for India and conforms to RoHS, so tell us the country of installation and we confirm the band, the variant and the compliance position before you order.

Yes, and that is the normal way in. Pick one measurable job, such as sub-metering one feeder, watching one DG tank or one cold room, and tell us the signal type, the distance and the reporting interval. We specify the devices and the gateway, you confirm the data reaches your platform, and the same network then takes on more points. The pilot kit on this site is one gateway and a few devices for exactly that; there is no minimum order to talk to us.
