Compact outstation with data logging and local control RTU8 INTRODUCTION The RTU8 unit is a compact outstation with data logging facilities designed for use in the industrial environment. The unit is designed in a very compact 108/162 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 RTU8 can be delivered with a built-in mains power supply and a charger (with a battery monitor) for an external lead acid battery, enabling the RTU to operate regardless of interruptions in the mains supply. The RTU8 has a number of integral inputs and outputs and further I/O´s can be added via an expansion bus. The RTU8 is compatible with the Brodersen Series 2000/4000 product range and thus a wide variety of expansion modules can be easily connected to the unit by standard cables. The unit can be programmed to perform simple control sequences using an IEC 1131-3 (PLC) programming language. The RTU8 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 IOTOOL32. When connected to a GSM modem the RTU offer a simple SMS message alarm option. The Modbus RTU protocol is used for data transfer from the RTU8 to a PC either directly or via Hayes compatible dial-up modem, GSM, or radio modems.

Compact outstation with data logging and local control RTU8 TECHNICAL DESCRIPTION Input/output The RTU8 basic I/O fit can include up to 32 input/output terminals. Serial I/O options are available: Version UCR- 8DIO 16DIO Digital inputs 8 16 (10-30V DC) Digital outputs 8 16 (PNP o. c.) Analogue inputs 0 0 (0-10V/4-20mA) Relay outputs (NO) All digital I/O´s are equipped with opto-couplers. The analogue inputs have galvanic isolation between the individual channels. Solid state relays are used for multiplexing the analogue inputs. Spare terminals 8 digital inputs + External + supply 10 - 30V...

Compact outstation with data logging and local control RTU8 I/O expansion The basic I/O fit of the RTU8 can be expanded by attaching System expansion modules. RTU8 with expansion modules BRODERSEN BRODERSEN Expansion modules are available with the following I/O configuration: 8-32 10-30V inputs 8-32 10-30 V PNP (or NPN) open collector outputs 8 230V inputs / 8 230V outputs (potential free relay) 4-8 analogue inputs (0-10V, 4-20mA, etc.) 8 Thermo coupled inputs (J, K, R, S, T type) 8 Pt-100, Pt-500 or Pt-1000 RTD inputs 4 analogue outputs (0-10V, 4-20mA, etc.) A maximum of 30 expansion...

Compact outstation with data logging and local control RTU8 I/O addressing (B-CONW) The address of the I/O in the RTU8 has the same structure as other Series 2000/4000 products. The I/O´s are separated into 4 data types; Digital I/O (DI/DO) Reflect the physical digital input and output on the node (module inclusive any I/O expansion). If you want to have them in our IOTOOL32 database, they need to be defined in the B-CONW application program. Digital input (DI): Bit input: i0.0, i0.1…..i0.7, i1.0…i1.7, i2.0…… i0.0 loads the first digital input (input 0). i1.0 loads digital input number 8...

Compact outstation with data logging and local control The up-loading of data from the RTU8 can be: • Event driven (such as an alarm). • Upload on request from the RTU8. The RTU8 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 RS232 or modem to Theactual process values to be loggedare selected using the IEC1131 - 3 programming facilities in the RTU8. Data...

Compact outstation with data logging and local control RTU8 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...
