DEVICE SPECIFIC FEATURES
Internal Indication IIN1-6 (Device trouble): Set to indicate a change in the current DNP
configuration in the outstation. Cleared in the next response. Used to let the master station
know that DNP settings have changed at the outstation. Note that some erroneous
configurations could make this condition impossible to communicate to a master station.
This document also states the DNP3.0 settings currently available in the device. If the user
changes any of these settings, it will set the Device Trouble Internal Indication bit on the
next response sent.
Event buffers: device can hold as much as 50 Binary Input Changes and 50 Analog Input
Changes. If these limits are reached the device will set the Event Buffers Overflow Internal
Indication bit on the next response sent. It will be cleared when the master reads the
changes, making room for new ones.
Configuration Operation Enable menu: the device can enable or disable permissions for
operations. If permissions are configured off (disabled) the response to a command (issued
as Control Relay Output Block) will have the Status code NOT_AUTHORIZED. If the
equipment is blocked the only command allowed is to Reset it.
Configuration Binary Inputs/Outputs menu: what is shown on the Point List is the default
configuration (as shipped from factory or after a reset by means of F4 key), but customers
can configure Inputs/Outputs to suit their needs, by means of ZIVerCom software.
Deadbands
Deadbands are used for configuring Analog Input Change objects (Object 32).
A Deadband is defined as a percentage over the Full Scale Range (FSR). In this device, for
differential currents and restraint currents, the FSR is defined in the notes under Analog
Input objects of the Point List.
A Deadband setting of 10% means that a change equal or greater than ± 0+/- 1,68A in a
differential current or +/- 16,8A in a restraint current between last-reported value and the
current value is required to generate an event.
The Deadband can be adjusted to the device by means of HMI (Human-Machine Interface or
front-panel user interface), between 0.00% and 100.00%, in steps of 0.01%. Default value is
100.00%, meaning that generation of Analog Change Events is DISABLED for that input.
There is an independent setting for each Analog Input.
