SPT4-NET Protocol Translator / Data Concentrator
Applied Systems Engineering, Inc.'s SPT4-NET is a Protocol Translator and Data Concentrator product with one network channel, four serial channels, and a large software library of RTU/IED communication protocols. It provides cost-effective support for a wide array of protocol and data transport applications common in the SCADA industry. These include operating as a data concentrator, translating one protocol to another, adding dual-port capability to an otherwise single-ported device, providing network access to serial-only equipment, and transporting legacy bit-protocols over a frame relay, or similar network.
SPT4-NET Protocol Translator / Data Concentrator
Designed for operation in a substation environment, the device does not contain disk drives. It operates on input power of 24 to 160 VDC or 110/120 VAC. The serial communication interface supports speeds up to 56 KB for byte protocols and 9600 baud for bit protocols. The Ethernet port supports 10Base-T operation.
Support is available for a large number of serial protocols, including present-day ones such as DNP3 and IEC 60870-5-101, as well as legacy "bit" protocols such as Conitel and CDC. The Ethernet channel can be configured for DNP 3 LAN/WAN, Modbus/TCP, and IEC 60870-5-104. Support of both master/host and remote/slave operations are available for all protocols. Each communication port, serial or network, can be configured for a different protocol as well as for master or remote operations.
SPT4-NET's software protocol translation "engine" is based on ASE's protocol library product, a set of field-proven routines that process the protocol unique aspects of data communication messages. The hardware design is based on ASE's field-proven BCOM8-56K PCI-bus I/O board: a processor based, 8-channel, high-speed, serial communications device used by several SCADA companies as well as other ASE products.
The SPT4-NET Configuration Editor is a graphical based tool for easy and convenient generation of configuration files used by the SPT4-NET Application. Device, and point configuration information is specified through this Windows based utility program and downloaded through the SPT4-NET configuration and maintenance port, or through a network connection.
The configuration editor employs standard Windows procedures. An entire data base configuration can be entered and running within a few minutes. Changes to an active database can be downloaded and activated in seconds to minimize the entire configuration test and development process.
During on-line operation, point data and communication statistics are accessible through a standard web browser. More detailed diagnostic and program status information are available through the configuration utility. This can provide valuable information during the initial installation stage, as well as a useful tool for on-going maintenance.
Key features of the SPT4-NET are presented in the following table:

SPT4-NET-I (with enclosure)
An evaluation package, including the Configuration Editor and SPT4-NET Application software for use under Windows, is available. Please contact Applied Systems Engineering for more details.
Available protocols include DNP 3.0 (serial and LAN/WAN), IEC 60870-5-101, and IEC 60870-5-104, in addition to many legacy ones such as Conitel, CDC 1 and 2, Telegyr 8979, Harris 5000/6000, and RP570. Click Here for a full list.
SPT4-NET pricing includes per-unit charge for the hardware and a license fee for the protocol support software.
The protocol license fee is a one-time charge of $750 per protocol. This fee entitles the licensing company to unlimited use of the protocol on all SPT4-NET and SPT-PC units. Separate license fees are charged for master and slave implementations of the same protocol. Category "C" protocols, as described on the Protocols Available page, may be subject to a development fee. Please contact ASE for more information. There is no development fee for Category "A" or “B” protocols.
SPT part SPT4-NET-I (pictured at the top of this page) includes an internally regulated power supply for operation at 24 to 160 VDC or 110/120 VAC and a full enclosure. An option for operation with regulated 5VDC input power is available. Please contact ASE for more information
