The NTX Explorer and Monitor programs are installed on a PC the Microsoft® Windows® XP and Windows 7 operating systems. It emulates the standard PC Windows Explorer file management system in order to minimize special training requirements. Drag–and–drop techniques are employed for database–mapping. NTX Explorer is used for configuration of the unit; in the field or the convenience of your office. Using Ethernet links to the NTX controllers provides an easy way to remotely download or upload a configuration to or from the controller via the WAN. Available configuration parameters include baud rate, Virtual RTU addresses, modem type, local I/O configurations, etc. All configuration changes can be made independently, stored in a file on the PC, and downloaded to the NTX when it is convenient. The configuration currently stored in the NTX can also be uploaded to the PC.
The NTX Monitor application is used for field diagnostics. It can display real–time data and functions such as binary and counter inputs, SOE data, analog points, IED inputs and outputs, state and activity of the binary output system, and internal LAN traffic. Local and IED control points can be tested directly in NTX Monitor. It is very helpful in the troubleshooting of IED communications (through the monitor of communications statistics for each connected device) and miscellaneous application problems.
Monitored local input data can be modified manually by a technician for testing or database verification purposes. Monitored data has two quality flags associated with each data value in the database:
- data that is not updating from the external source (off–line IED, etc.) is displayed with a yellow background
- manually modified data is displayed with a red background
With a high-speed Ethernet interface to the controller, NTX Explorer can be connected via a WAN for convenient remote configuration.
