Introduction

EdgeBox-ESP-100 enabled SCADA equipment via software selectable 4G/LTE to remote networks or select Industrial Internet of Things (IIoT) Cloud platforms. Featuring an event-based engine that can trigger I/O or send SMS text messages based on real-time operational data, EdgeBox-ESP-100 controller can perform advanced local edge control and alert personnel of critical events. A built-in I/O concentrator allows the controller to collect sensor data and optimize cellular data consumption by optionally reporting only on an exception or only transmitting relevant data points. With built-in Ethernet, serial, I/O and GPS, EdgeBox-ESP100 controller easily integrate with existing equipment enabling remote monitoring and control for M2M applications in industries including oil and gas, water, utility, transportation and mining.
1.1. Features

• Rugged, reduced-maintenance hardware
• High isolation, surge, and short circuit protection
• Open architecture support custom programming
• Ethernet, I/O ,4G/LTE, CANopen and Modbus bridging
• Natively Supports Modbus & CANopen Protocols
• Cloud Connectivity to IIoT Cloud Platforms
• Integrated wired solution for all analog and discrete I/O interface designs
• IEC 61131-3 compliant programs support (under developing)
• 35mm DIN Rail support
• Wide power supply from 1.8 to 36V DC

These features make the EdgeBox-ESP-100 designed as a cost-effective controller that provides the functions required for a variety of field automation applications. The EdgeBox-ESP-100 monitors, measures, and controls equipment in a remote environment.

2. GND and AGND are isolated.
3. All AGND signals are connected internally.
4. DC voltage for input is 24V(+- 10%).
5. DC voltage for output should be 24V(+- 10%). , the current capacity is 1A.

2.2.2. Serial Port (CAN BUS and RS485)

NOTE:

1. The 120 Ohm termination resistor for RS485 has been installed inside.
2. The 120 Ohm termination resistor for CAN BUS has been installed inside.

2.2.3. Ethernet
Ethernet interface comes from W5500, and connected ESP32 with SPI signals,10/100-BaseT supported, available through the shielded modular jack. Twisted pair cable or shielded twisted pair cable can be used to connect to this port.

2.2.5. SMA Connector
There are two SMA Connector holes for antennas. The ANT1 is default used for Mini-PCIe socket and ANT2 is for Internal WI-FI signal from CM4 module. 2.2.6. SIM card slot
The sim card is only needed in cellular network mode. 2.2.7. Reset button The reset button has multiple functions.

1. When power up, the button is used to boot in download mode, it is useful if the OTA mode is crash.
2. In APPs, the user software can use the button to “RESET” to default user configurations, such as IP Address, Wi-Fi information, or other behavior and action.
