Remote control connection
The relay can be connected to higher level systems, e.g.
network control systems via the serial port named REMOTE on
the rear panel. To the port a SPABus, ModBus, ProfiBus
or
IEC-103 connection can be made using a special internal or
external bus connection module. The bus type selection and the
parameterisation of the bus are carried out as the relay is
configured.
Optional accessories are available for RS485 connection (VMA
3CG), Ethernet connection with TCP/IP protocol (VEA 3CG)
and Profibus connection (VPA 3CG). Please see the
corresponding documentation for more details.

Disturbance recorder
The disturbance recorder can be used to record all measured
signals i.e. currents and voltages, status information of digital
inputs (DI) and digital outputs (DO). The digital inputs include
also the Arc light information (S1, S2 and Arc binary input BI).
The digital outputs include the Arc binary output information
(BO).
Recorder capacity is 48 000 bytes. There can be a maximum of
5 recordings and the maximum selection of channels in one
recording is 12 (limited in waveform recording).
