AD-LU 610 GT

Description

The digital power measuring transducer AD-LU 610 GT measures all quantities of the three-phase network (current, voltage, energy, harmonics, phase angle, active power, reactive power, apparent power etc.) and converts these measuring values onto two freely scalable analogue outputs (20 mA / 10 V). With the integral relay, the switching of limiting values or the output of energy pulses is possible. For output of more frequent energy pulses, the AD-LU 610 GT is alternatively also available with transistor output. The unit is therefore optimal suitable for integration in energy management systems. 3- or 4-wire systems can be measured.The AD-LU 610 GT is supplied via its measuring voltage L1. The current measuring is carried out via the bar-type transformer mounted on the front. For measuring of high voltages or high currents, external transformers can be connected in series at any time. The AD-LU 610 GT can be read out and parameterised via the integral RS485-interface with the aid of the available AD-Studio. A 96x96 mm TFT display module can also be connected to this interface. The LEDs at the front signals the operating condition, the RS485-data and the relay-status. The compact type of construction and the high performance ability with simultaneous low energy consumption allows usage in almost any application.

Modbus Communication

The AD-LU 610 GT has a RS485 bus interface on which the Modbus RTU protocol is used. About this bus interface all measured data of the unit can be read out.
The default standard data format is 19200,e,8,1. Adaptation to a different data format is always possible.

data rate: 19200 baud (bits/s)	parity: even	data bit: 8	stop bit: 1

The bus address is set at the front mounted rotary switches. The address 0 is prohibited for bus application. However, on this zero position the device always uses the standard data format (19200, e, 8,1). The position 0 therefore represents a service position, can be used for example at incorrect parameterization.

The AD-LU 610 GT supports two Modbus functions. These are the functions "Read Holding Registers" (0x03) and "Write Multiple Registers" (0x10) . The function "Read Holding Registers" data can be read from the device and data is written with "Write Multiple Registers" . The individual register width is 16 bits.
Please refer to the Modbus specification for a detailed description of the Modbus communication. This is freely available online, but can also be obtained from the Adamczewski homepage.

The following Modbus data are accessible via the RS485 bus:
