Overview

The SCADALink IOT100 is a compact, low-power cellular connected gateway device designed for Industrial Remote Monitoring, Control, & Alarm Callout Applications.  The IOT100 is coupled with the SatSCADA Web Portal to provide Plug-and-Play Remote Monitoring and Alarm Callout Operations. The IOT100 can also provide multipoint I/O telemetry, securely transmitting data over cellular network.

The SCADALink IOT100 is available in complete, ready to install AC and DC powered packages.

Compact, Integrated Functionality

• Integrated CAT-M1 cellular communications for reliable data wherever there’s connectivity.
• 2 x Digital Input to detect on/off states (e.g. pump status, door alarms).
• 2 x Digital Output to remotely control devices (e.g. valves)
• RS485 Modbus Master/Slave Port for connecting with industrial devices
• DIN Rail Mount Package for easy installation
• GPS for Asset Tracking for tracking your location
• Direct 4-20ma/ Voltage Sensor Inputs:
  • 1 x 4-20mA Input for industrial sensors (pressure, level)
  • 1 x 0-36 VDC Input for battery and power monitoring
• Class 1 Div 2 Rating
• Wide Temperature Operation
• 10-30 VDC Operation

RS485 Modbus Master/Slave Port

The Modbus Master Port allows the IOT100 to poll Modbus Slave Devices like PLCs, RTUs, Flowmeters, and Engine/Generator Controllers.

The Modbus Slave Port allows the tag based data from the local or remote IOT100’s to be retrieved by a master PLC/DCS device or SCADA Host.

I/O Expansion with SCADAlink I/O Modules

The IOT100 with the SCADALink I/O bus allows SCADALink IO Modules to be used to expand I/O for applications with additional I/0.

• DI8
• AI4
• DO8
• AO8
• COMBO-I/O

Low Power Operation

The IOT100 with low power sleep mode allows it to be used in SOLAR and/or BATTERY powered applications.  Units in Sleep Mode can be automatically woken on schedule and/or any digital input state change. Subscribed tag data and configuration changes stored by the broker will be delivered once the device wakes up.

Intuitive Tag Based Configuration

The I/O is organized by user defined descriptive tag names. Each IOT100 can publish data to the server on schedule or event/change, as well as subscribe to any tags published by other IOT100’s in the same network or published via the SATSCADA dashboard. Alarms can be defined based off any tags with setpoints that can be changed/updated from the SatSCADA dashboard.

Integrated SatSCADA Cloud Portal For Monitoring and Control

The IOT100 automatically publishes all data to the SCADAlink SatSCADA Platform on schedule or based on alarms/events. The SatSCADA web portal provides a secure and intuitive interface for:

• Remote Monitoring: View real-time and historical site data.
• Data Trending: Analyze performance and spot trends over time.
• Alarm Notification: Receive instant alerts via Email, SMS, and voice callout for critical events.

I/O Telemetry

The SCADALink IOT100 can both publish and subscribe MQTT data from the SatSCADA Cloud.  By subscribing to tags from other IOT100 units in the same network,  point to point or point to Multipoint I/O Replication/Telemetry can be performed. 

The IOT100 is designed to handle applications where I/O signals (4-20ma Input/Outputs, Digital Inputs/Outputs) have to replicated from one site to another. These may be applications for wire replacement or simple remote control.

The IOT100 using cellular network communications and a SatSCADA MQTT broker enable I/O Telemetry connectivity over RF obstructions / terrain.

With the SatSCADA Platform support users can control and view data on dashboard.

Figure 1 – I/O Telemetry

The SCADALink IOT100 is ideal for remote monitoring applications where there is need to monitor and control a small amount of  Tags derived from hardware I/O  (4-20ma Input/Outputs, Digital Inputs/Outputs) or Modbus Devices.  A IOT100 can be easily configured for a applications like Tank or Reservoir LEVEL monitoring as shown.

SCADALink 485Hub – RS485 Hub

The SCADAlink 485HUB is a RS485 Hub designed for connecting RS485 field devices in rugged industrial applications. The DIN Rail mounted 485Hub features RS232/RS485 inputs and 3 isolated 2 wire RS485  output ports.  The 485HUB features low power operation, wide voltage operation range (10-30 VDC) and Class 1 Div 2 rating.

RS232 and RS485 Inputs

The RS485Hub has RS232 and RS485 inputs allowing direct connection from PLC, RTU, Computers, Ethernet to Serial Terminal Servers and Modems to RS485 field instruments.

The 485HUB has an RS485 bus that allows multiple 485HUBs to be bussed together to expand the hub from 3 to 6, & 9 ports.

Operation

All data on the RS232 and RS485 input port is transmitted to the RS485 Hub ports.  Receive traffic on RS485 Hub Ports are transmitted only to the input port. Up to 32 RS485 devices can be connected to each hub port. Each hub output port is individually isolated to protect from surges of any port affecting equipment on other ports. Isolation and independent drivers on each port minimize device loading and end of line termination issues affecting RS485 communication. Even a wiring fault on an individual hub port will not affect communications on other ports. Since the RS485 hub ports are isolated,  problems on a single hub port can be easily isolated and resolved.

Simple Terminal Block Wiring

Each of the 3 RS485 Hub Ports is terminated on its own individual removable connector.  RS485 field wiring can be connected directly to the removable connectors.  Individual RS485 connectors can be easily disconnected to isolate and troubleshoot a specific connection.

A USB maintenance port, when connected, overrides the input port, allowing easy troubleshooting.

RS485 Star Wiring  Network Topology 

The 485HUB is designed to connect longer RS485 wiring runs in a star topology from a central location.  Each hub port is an independently isolated channel. Isolation and independent channels prevent grounding, device loading, termination problems, signal loss, and noise on one RS485 connection from affecting the RS485 network.  A Hub topology simplifies system troubleshooting.

Isolation  

The 485HUB is ideal for applications where there are multiple remote RS485 connected field instruments. Independently isolated hub ports allow wiring connectivity in a simple star network topology to ensure higher reliability RS485 networking and increasing uptime and minimizing commissioning, maintenance, and troubleshooting costs.

Long RS485 instrument cable runs should use an individual RS485 hub port for maximum isolation and protection against surge and lightning damage to equipment in the connected network.

The length of each individual RS485 run can exceed 4000′.

USB Input Override

The 485HUB has USB Input Override mode where the input is bypassed by the USB when connected, allowing maintenance access to the RS485 connected devices with the removal of RS485 wiring. This ideal for maintenance and configuration of RS485 instruments.

RS485 HUB Features

• Industrial RS-232/RS-485 to isolated 3-port, 2-wire RS-485 HUB
• USB input port for USB override
• Terminal block field connections
• 35 mm DIN-rail mounting
• Class 1, Division 2 certification
