Remote table

Data is acquired from remote devices such as RTUs and PLCs. Each remote record provides configuration details on one remote device. Remote records are located in the remote table and are configured using the remote Row Edit dialog box.

Acquired data refers to the telemetered data values that measure conditions such as pressure and temperature in the field. It also includes data sent from the remote site to the system in the form of text messages that indicate alarm and event conditions. These text messages help to monitor the process conditions and will alert you to problem situations.

Data and commands are transferred along the connection between the host computer and the remote device, for example RTU, PLC and between that remote and its attached field devices.

A variety of devices serve as remote processing units (remotes) to process and transfer the field data back to the host. These include different Remote Terminal Units (RTUs), Gas Chromatographs (GCs), Programmable Logic Controllers (PLCs), and Flow Computers (FCs). The remote scans the field devices that are mapped into the RealTime database (RTDB) by unique data input/output coordinates. Data is passed between the remotes and the host computer through a connection.
