Distributed busbar protection REB500
Section 3 HMI500
3.1 Introduction
This section describes the human/machine interface (HMI) for the protection
systems REB500. For a detailed explanation of signals and parameters see
“Technical manual”. For a description of fault finding actions see Section 6 “Fault
finding”. For details on security settings see “Cyber security guideline”.
HMI500 is a convenient human-machine interface which permits the operator to
view measurements and statuses, to set protection functions, to configure the
system, to download the latter data to REB500, and to control the disturbance
recorder and event memory integrated in the system.
The data are transferred between the PC and REB500 via an Ethernet interface
attached to the front of the central or bay units. The PC can be connected of the
station bus as well.
Any changes (e.g. settings, configuration etc.) made using HMI500
are stored in a specific customer database (MS Access database file)
on the PC and not in the protection system. The database then has to
be downloaded from the PC to the protection system (see Section
3.4.1.).
3.2 Safety instructions
HMI500 permits circuit-breakers and isolators to be operated.
Every program operation and the possible consequences must be
considered carefully beforehand. If switching operations have to be
carried out, the same precautions must be taken as when performing
them manually.
Earlier HMI500 versions are incompatible with Version 8.00 of
the protection system software.
When the HMI500 software establishes communication with a
REB500 system initially user must enter a password. For details
about security management, passwords and security options refer to
“Security Deployment Guideline” (1KHL020774-Aen).
