MODEL 50386 : Real-Time Data Transmitter
SCADA Two-Way Transmitter

General Description:

The Model 50386 Real-time Data Transmitter collects, processes, and transmits analog, digital, and serial sensor data on events and timed intervals. The collection, processing, and transmission of sensor data is controlled by parameters that are programmed using the 50386 Toolbox software. The sensor data can be transmitted using multiple communication paths with mixed formats and protocols.

The HydroLynx Model 50386 ScadaLynx uses dual processor architecture and the latest in embedded processor technology to minimize power usage when idle and maximize computational power and performance when awake. The main processor is an Intel 386EX microprocessor that runs the main data collection, data telemetry, and control processes. The second processor is a low power PIC I/O processor that collects digital status and counter data. When the main processor is idle, it is put to sleep to conserve power. The PIC I/O processor wakes up the main processor on timed intervals, when digital event thresholds are met, radio carrier is detected, or data is entered on the console communication port.

Standard memory on the Model 50386 consists of FLASH, Battery backed SRAM, EEPROM, and a battery-backed Real-time Clock (RTC). 2 MB of nonvolatile FLASH is provided for program and configuration file storage and data logging. Although stored in FLASH, the program is copied into battery backed SRAM (512KB) for faster execution. Current sensor readings are saved in nonvolatile EEPROM (8KB) and the RTC stores the time in its own battery-backed SRAM. The contents of nonvolatile and battery-backed memory are not lost when power is removed.

The Model 50386 Data Transmitter is programmed using a Windows based Toolbox software package. Transmitter programming can be done directly using either one of the two onboard RS232 serial ports or remotely through telemetry equipment connected to these ports. The programming parameters include station identification; sensor I/O identification, scaling, sampling, computations, logging threshold, reporting threshold; alarm or control actions; communication parameters; power down settings; clock time and time zone; and data logging format and limit.

The Model 50386 Data Transmitter supports up to 16 analog inputs, 16 bit Analog to Digital converter, 12 digital status inputs, 4 low speed up/down counter inputs, 4 high speed up only counter inputs, 6 digital outputs, and 1 SDI-12 serial interface. Serial data collection is possible through one or more RS232 serial ports.

Virtual sensor data can be computed from sensor inputs to compute sensor averages, maximums, minimums and runtimes. Virtual sensor data can then be tested, alarmed, logged and transmitted just like actual sensor inputs.

Six digital outputs allow the 50386 Data Transmitter to perform local controls based on sensor upper, lower and change limits. Control resets are based on reset value and time interval limits.

Two RS232 serial ports in the standard package can be expanded to six ports to increase the number of communication paths. Communication formats include ALERT/IFLOWS, ScadaLynx, ASCII, and MODBUS. Communication paths can be through ALERT radio transceivers; SCADA radio transceivers; telephone, leased-line or microwave modems; GOES transmitter; direct serial connections.

Packaging for the Model 50386 includes the standard ALERT style canister and NEMA-4X fiberglass enclosure.
