Just like SIMATIC - but for energy automation
Telecontrol and automation, two seemingly unequal partners, are growing together with SICAM RTU. The fact that they work together so harmoniously in one system is the result of an innovation in SIMATIC. In actual fact, SICAM RTU is based on essential parts of the SIMATIC 400 power PLC. Particularly for the requirements of the energy-oriented area, the system provides all round 2.5 kV isolation. Messages are registered in real time with a resolution of one millisecond. All modules continuously check themselves and can even be replaced under live voltage during operation. These are only a few examples of the high reliability and availability afforded.

The system solution that speeds you up
For telecontrol tasks, SICAM RTU offers you self-contained functionality with which you now only need to define the parameters. This ensures fast system availability for you. You decide, for example, whether you want to use the two independent transmission channels for communication with two system control centers or for redundant transmission to one control center. You parameterize the typical telecontrol functions on the modules themselves and then your SICAM RTU is ready to run straight away. You can program the automation functions freely to exploit the whole diversity of this technology from generation of simple group indications to automatic starting and stopping for generators.

Modular and future-oriented
SICAM RTU is also an economical solution because it is based on the modular principle. No matter what your basic version looks like today, tomorrow you can also add project-specific options. Your investments are protected thanks to strong standards from the hardware basis through the communication standards to the Windows operating system.

The Input/Output Modules of the basic system
The Input/Output Modules of SICAM RTU family is intelligent function modules that meet all requirements of the automation of geographically widespread processes. In additional, all input/output modules, which are Digital Input Function Modules, Command Output Function Modules and Electronic Analog Input Function Module, have been designed with the basic features to make telecontrol system easy to handle.

The Telecontrol Processor
The telecontrol processor supplements the CPU with its range of functions. In the SICAM RTU, the Telecontrol Processor handles all tasks connected with the safe and reliable remote transmission of data to the control centers.

Digital Input Function Module (DI32 - 6MD1021)
It is used in SICAM RTU family to input signal and counting pulses. The digital input module is available in two models. Each of the models is used for different input voltage ranges. The features are 32 binary process inputs, acquisition of process changes with a real-time resolution of 1msec, parameterizable input filter, cyclic acquisition of states, spontaneous acquisition of events, parameterizable conditioning by byte, safe and reliable acquisition of the signals states, sensor for recognition and monitoring of the indication circuit voltage, and standard diagnostic facilities.

Command Output Function Module (CO32 - 6MD1022)
It is used by the SICAM RTU family to output commands. Safe and reliable command output is provided by the control output CO32. The features of it are 32 outputs, time-controlled output of single commands or double commands, command output reliability can be selected via various operating modes, time-independent command output, internal output safety, switching capacities for ohmic, and standard diagnostic facilities.

Electronic Analog Input Function Module (AI32 - 6MD1031)
It is used in the basic system of the SICAM RTU for the acquisition of analog measuring values. The analog input module available with current inputs or voltage inputs. The features are 32 floating analog inputs (one command root), parameterizable measuring ranges, single or bipolar, for current or voltage measurement, analog/digital conversion via sigma-delta procedure, cyclic acquisition of states, spontaneous acquisition of events, automatic self-calibration, signaling for failure or deviation which cannot be corrected, and standard diagnostic facilities.

Telecontrol Processor (TP1 - 6MD1010)
It handles all tasks connected with the safe and reliable remote transmission of data the control centers. The telecontrol processor supplements the CPU with its range of functions. The TP1 is equipped with two serial interfaces for safe and reliable communication with up to two control centers. Other possible connections on the TP1 include monitoring sockets for the individual interfaces and a synchronization input for connection of an external clock module. The operating diagnostic indications on the front provide information on the status of TP1 at all times. The serial interfaces are V.24/V.28 and RS422 interfaces which can be selected by parameterization.
