INTERFACE CONTROLLER FOR IOT SOLUTIONS EM-481

EM-481 provides data collection from connected MODBUS devices, data transfer to the server, data access via MODBUS TCP (GPRS, Ethernet) or SMS text messages (GSM), event tracking and response to events (sending SMS notifications, recording values to MODBUS devices).

EM-481 provides:

· Flexible options of connection (via wire or wireless communication, automatic method selection of communicating with a server, automatic or manual selection of GSM provider and communication parameters,

resetting of MAC-address and other Ethernet settings;

· Protection of access (password for setting mode, filter of IP-address for setting or connection to Modbus network, connection only to the selected server with automatic login, password for control via SMS);

· Different modes of data interchange via MODBUS network (RTU or ASCII, with checking of parity for even-odds or without checking, wide range of transmitting rate, adjustable delay);

· Programming the collection of data, events, and action for events (see Appendix С);

· Service functions (real time clock, firmware updating option).

The device provides control for MODBUS devices in RS-485 network via Ethernet interfaces or GPRS, or via SMS. The device also allows reading data of devices by MODBUS. The processor supports connection to cloud-based data collection server via Ethernet network with a help of microchip of physical interface of Ethernet (or via GPRS with a help of in-built GSM-modem, if connection via Ethernet is not available).

In addition, the device can be connected to Ethernet via MODBUS TCP Protocol to exchange data with MODBUS devices, or with EM-481. The controller receives and processes SMS with a password and command read/write for Modbus devices.

When inserting a memory card the device reads the internal memory for operational logic – program for data collection and tracking of events. The program runs in the background mode.

The device stores the network settings, safety parameters, the logic of action, the collected data log in the built-in memory.
