RTU-COM-1

RTU-COM / Compact outstation with built-in modem The RTU-COM unit is a compact outstation / RTU with built-in COM device as PSTN dial-up or GSM dual band modem. The unit has data logging facilities and is designed for use in the industrial environment. The unit is designed in a very compact 162 mm wide module for DIN- rail mounting (35 mm symmetrical ). Dimensions conform to DIN 43880 (used for circuit breakers) thus insuring easy installation in standard installation panels and boxes widely available in the electrical industry. The RTU-COM can be delivered with a range of different power supply versions including a battery/solar panel option. Different power save options is available in the RTU-COM. When closing down modem and analogue circuits and enter into sleep mode the power consumption can be reduced to a minimum. All sleep mode facilities are controlled from the application program. The RTU-COM has up to 16 integral I/O, covering digital inputs and outputs, and analogue inputs as process signal or temperature sensor inputs. 2 SO counter inputs for flow meters etc. on all versions. The unit can be programmed to perform simple control sequences using an IEC 1131-3 (PLC) programming language. The RTU-COM includes facilities for local data logging, the process values to be logged are defined as part of the IEC 1131-3 application program. Programming, setup and data transfer is achieved by using the In addition the RTU-COM can be programmed with the Straton for B-CON tool providing support for the IEC1131 programming languages Function Block and Ladder. In the RTU-COM version with integrated GSM dual band modem the RTU offer a simple SMS message alarm and control functions.

RTU-COM / Compact outstation with built-in modem Data logging The up-loading of data from the RTU-COM can be: • Cyclic upload controlled by a central PC (for example 24 hours) • Event driven (such as an alarm). • Upload on request from the RTU-COM. The RTU-COM can log events and process values for later analysis. The data logging process can be divided into 3 sections: • Defining the events and the selection of values to be logged. • Storage of data, with time stamp, in the log buffer (max. 480k • Upload of the data from the module via Programmer port/ The actual process values to be logged are...

RTU-COM-7

RTU-COM / Compact outstation with built-in modem UCR-XX/RCX Log buffer The log buffer is a ring buffer (FIFO), in which the data is stored in the order they appear (up to 480 k bytes). If the buffer is not emptied, (uploaded via the RS232) the oldest data will be over written by new data, when the buffer is full. Each record in the log buffer is separated with DLE/STX characters. If DLE (hex code 10) appears in the data area, DLE stuffing is automatically inserted. The PC utility automatically removes the DLE stuffing during upload. One log record can contain up to 120 words of actual log data,...

RTU-COM-9

RTU-COM / Compact outstation with built-in modem UCR-XX/RCX The RTS Trailing setting defines the delay from the last character is transmitted to RTS is deactivated. Handshake RTS/CTS RTS is inactive when receiving data, and is activated when the RTU wants to transmit data. After activating the RTS, the RTU will wait for the CTS to become active, before start transmitting. The RTS Leading delay is still valid in this mode, and an adjustable delay from CTS is activated to first character is then possible. However by setting the Leading time to zero, there is no unnecessary delay from CTS to first...
