在RE. 216系统中永久存储的软件中提供了许多不同的保护功能。保护特定植物所需的功能可以是单独的
选择，激活和设置。一个特定的保护功能可以在不同的保护方案中多次使用。该装置的保护装置如何处理这些信号，例如将跳闸、信号和逻辑信号分配到各种输入和输出，也要通过适当配置软件来确定。
系统硬件采用模块化结构。实际安装的电子设备和输入/输出单元的数量，例如，为了增加保护功能的数量或为了冗余的目的，可以根据特定工厂的要求而有所不同。
由于采用模块化设计，可以通过配置软件选择保护和其他功能，因此发电机保护REG 216可以适用于小、中、大型发电机以及大型电机、电力变压器和馈线的保护，而控制单元REC 216可以在中、高压变电站中执行数据采集和控制监督功能。

每个RE. 216保护系统的设计都符合有关工厂的特定要求。为每个安装提供了一组特定的图表，其中定义了与所安装的电子设备和输入/输出单元、它们的位置和内部布线有关的系统。
这套植物图包括:
保护的单线图:设备的完整表示，显示到保护的ct和vt连接。
标准电缆连接:方框图显示保护设备布线(电子设备机架到I/O单元)。
保护隔间布局:电子设备和I/O单元的安装和位置。
电子机架布局:设备在机架内的位置。
测量电路(三相工厂图):连接直流和直流到保护装置。
辅助电源:外部连接和内部分配辅助直流电压电源。
I/O信号:脱扣和信号输出与外部输入信号的外部连接和内部接线。

A number of different protection functions are provided in the software permanently stored within the RE. 216 system. The functions required to protect a specific plant can be individually
selected, activated and set. A particular protection function ma be used several times in different protection schemes. How the signals are to be processed by the protection for the plant in question such as the assignment of tripping, signalling and logic signals to the various inputs and outputs is also determined by appropriately configuring the software.
The system hardware is modular in structure. The number of electronic devices and I/O units actually installed, for example, to increase the number of protection functions or for purposes of redundancy, can vary according to the requirements of the particular plant.
Because of its modular design and the possibility of selecting protection and other functions by configuring the software, the generator protection REG 216 can be adapted for the protection of small, medium and large generators as well as large motors, power transformers and feeders, while the control unit REC 216 can perform data acquisition and control and supervision functions in medium and high-voltage substations.

Each RE. 216 protection system is engineered to fulfil the particular requirements of the plant concerned. A specific set of diagrams is provided for each installation, which defines the system with respect to the electronic devices and I/O units installed, their locations and the internal wiring.
The set of plant diagrams includes:

single-line diagram of the protection: complete representation of the plant showing the c.t. and v.t. connections to the protection.

standard cable connections: block diagram showing the protection equipment cabling (electronic equipment racks to I/O units).

protection cubicle layout: installation and locations of the electronic equipment and I/O units.

electronic rack layout: equipment locations within a rack.

measurement circuits (three-phase plant diagram): connection of the c.t’s and v.t’s to the protection.

auxiliary supply: external connection and internal distribution of the auxiliary d.c. voltage supply.

I/O signals: external connection and internal wiring of the tripping and signalling outputs and the external input signals.
