Overview:

The ZNX6000 Station Manager is designed for the highest standards of performance, safety and reliability to meet requirements of a complex substation automation system (SAS). As a part of the SAS, it works as a station communication manager, which collects, stores and maps signals of relays, measurement units, control units and other IEDs in the substation to higher- level systems such as control center (CC) and distributed control system (DCS).
The ZNX6000 supports several protocols, such as IEC 60870-5-101/104, IEC 60870-5-103 and CDT. These protocols form a standard protocol package to satisfy most requirements. Data can be transmitted to and received from analog channel, digital channel or network connected to CC, DCS or other system. The direct transmission mode and the device independent avoid any interaction or influence with the the substation SCADA (Supervisory Control And Data Acquisition) system.

Funcations：
* Relay information acquisition
Through serial or Ethernet port, this device can communicate with protection relays to gather their information such as SOE records, tripping signals, supervision alarms, etc.
* Measurement & control IED information acquisition
Through serial or Ethernet port, this device can communicate with measurement & control IEDs and intelligent meters to gather their information such as sampled values, binary status, energy metering signals, etc.
* Auxiliary IED information acquisition
In addition, this device can gather information of other auxiliary devices, such as energy meter, which are useful or crucial for the operation and safety of substation.
* Remote control center communication
This device can realize the communication with multiple remote control centers with different protocols. The mapping transmission tables for different centers can be customized independently.
* Command record and query
This device records all the commands and operations, which include control selection, control execution, regulation, setting modification selection, setting modification execution, signal reset, etc. All these records can be viewed and queried with filter.
* History event record
This device automatically records the events during its service, which include self running state change, alarm from connected IED, communication failure alarm, etc.
* Time synchronization
This device supports several time synchronization formats, including IRIG-B, network SNTP, time message, etc. It can also
synchronize the connected IED with time message to unify the time in one substation.
