Data Acquisition System

Success Story

 

 

The principle of operation of the RDM-01 unit is based on the acquisition of data by means of serial communication protocols MODBUS RTU y Allen Bradley DF1 to collect information which allows it to connect and acquire information from a wide range of industrial instrumentation and control devices, such as electric power meters, motor protection devices, measuring instruments, programmable logic controllers (PLCs), etc.

The RDM-01 drive collects the information and stores it locally on a microSD-type memory unit; microSD memory unit allows local data backup for years of operation, for audit purposes, data backup, etc. Data can be downloaded locally to a PC via the Ethernet port.

Every hour, the system sends this information by means of an e-mail attachment to the configured accounts or to a central FTP data server via GPRS/GSM cellular link in CSV (Comma Separated Variable) format to be used directly by Excel sheets or well incorporated into data historization systems such as OSISoft PI or GE historian. The integrity of the information is ensured throughout the process of collection, storage and transmission, using CRC (Cyclic Redundancy Check) data verification algorithms.

The system allows the configuration of operation alerts (Low Pressure, High Flow, etc.) and sends them through SMS messages or e-mails to previously defined telephones and mail addresses, as well as remote control by means of SMS messages of two digital outputs in relay that can be used to remotely manipulate the operational status of control devices, engines, etc.
