Model 570 Fiberoptic Transceiver
FiberLoop III Network

The Model 570 hardware and FiberPanel software comprise the H&L Instruments FiberLoop III SCADA/DA fiber network solution. The Model 570 fiberoptic transceiver combines the capabilities of a transceiver and a controller in a single powerful unit. You can perform SCADA master, slave, and peer-to-peer communications within the same device making it a highly flexible solution. The FiberLoop III network, consisting of the Model 570 and FiberPanel software, are used for a range of applications that include:

The Model 570 transceiver is a self-healing, single mode fiberoptic transceiver that features 127 independent, high speed (115Kbps) virtual network communication channels and four to sixteen serial ports. You can assign each serial port to any virtual channel, which allows grouping Remote Terminal Units (RTUs) with common protocols. Two 10/100 802.3 compliant Ethernet ports are available as an option.

The FiberPanel software is included with all Model 570 devices to implement a FiberLoop III network. The FiberLoop III network supports multiple RTUs, Intelligent Electronic Devices (IEDs), Programmable Logic Controllers (PLCs) and microprocessor-based relays. In addition, you can segregate different applications, allocate network bandwidth, and share backup master stations. The FiberLoop III solution is optimized for use with Schweitzer Engineering Labs Mirrored Bits Protocol™. In H&L's redundant loop configuration, a FiberLoop III network can self-heal and reconfigure from loop to radial mode so quickly (4 msec) that relays such as the SEL-351 cannot detect the fiber break.

The Model 570 transceiver is highly reliable, fault-tolerant, redundant, and offers both a rugged and cost-effective solution for self-healing ring and radial network designs. In addition to peer-to-peer communication, this device also supports all byte protocols including DNP and UCA.

16 Serial Data Channel Option

The Model 570-16 option provides 16 high speed serial data communications channels for master/slave supervisory control and data acquisition systems (SCADA). In controller mode, this device automatically reroutes data in the event of a fiber break or transceiver failure. In transceiver mode, the device provides the interface with all remote devices including RTUs, PLCs, and IEDs.

IntelliTeam II Option

The Model 570i incorporates the IntelliTEAM II option to operate with the S&C 5804 Controller. This version of the Model 570 Transceiver is designed using a short case that has a form factor dimensionally compatible with the S&C controller. The S&C 5804 IntelliTEAM II® Controllers operate from a 12 volt power source. The Model 570i incorporates a high-efficiency 9-36V power supply for easy integration and compatibility with the S&C products.

All Model 570 transceivers are bundled with the FiberPanel III configuration and diagnostic software for managing the fiberoptic network.
