Scout Station Controller (SSC)

• RTU, Data Concentrator and PLC functionality in one device
• Database Capacity of 16K Points
• 13 Serial Communication Ports
• Ethernet and Fiber Optic Communication Ports
• Terminal Server Functionality
• Built-In Web Server
• Points Mapping Wizard
• Time Synchronization (IRIG-B)

The SCOUT is a member of the Station Controller family of devices. Station Controllers not only combine the functions of a traditional RTU with the functions of a PLC and Terminal Server, but also include a Web Server and Data Concentrator. Extensive communications capabilities are available over both serial and Ethernet networks. For detailed information regarding options, please refer to the SCOUT Specification and the SCOUT Specification Guide.

A major benefit of the SCOUT is the capability to do remote diagnostic over the network connection. Communication on all active ports can be monitored; settings can be viewed and modified and files can be loaded/updated including mapping and the SCOUT application software.

The SCOUT can act as 4 virtual RTUs to 4 different master stations with separate database mapping for each master

IED point configuration in the SCOUT can be done at the Survalent Master making it a very tightly integrated system that is quick and easy to configure.

STC guarantees support and availability of its Station Controllers for at least 10 years

Station Explorer is a PC-based windows program used to map both RTU hardware points and IED database points directly to master station database points. It combines map editing, compiling and downloading tools into one package, and consists of the following major functional parts:

• A ‘Hardware Point Map Editor’, which is used to edit Scout RTU hardware point maps.
• An ‘IED Configuration Wizard’, which guides the user to go through all necessary configuration procedures so that all necessary data is entered correctly.
• A ‘Point Map Compiler’, which compiles the point maps produced by ‘IED Configuration Wizard’, checks and reports any errors, packs the data in a predetermined format and save the binary map files onto disks.
• An ‘IED Database Editor’, which is used to input and manage the databases of different IEDs of different protocols made by different manufacturers.
• A ‘File Download Tool’, which is used to download the binary point maps produced by the ‘Point Map Compiler’ onto the RTU.

The database of the Station Explorer contains all the information of an IED that is required to request data points from the IED and on the format of the received data. This information is used when the IED is configured.

As an example in MODBUS, points can be retrieved using different function codes and although there are some standards for using the function codes, each manufacturer may use them differently and still comply with MODBUS. The data being returned can have many formats (signed or unsigned 16 bit value; signed or unsigned 32 bit values in two registers, etc) This information is set up once in the data base, and when it comes time to select points from the IED, the user does not have to worry about these details. In fact it is expected that the user will not have to consult the manual for the IED during this process.
