SR05-D1A3-PV manual v1801 37/83
6 Communication with SR05
SR05-D1A3-PV has a Modbus output that is compatible with the IMT-Solar
Si-RS485-TC-T-MB silicon reference cell: most of the Modbus functionality of the silicon
reference cell is also supported by SR05-D1A3-PV. This makes it easy to install
SR05-D1A3-PV in existing photovoltaic monitoring systems without the need to make
major modifications to the datalogging software or infrastructure.
In addition to the silicon reference cell compatible Modbus output, our standard
Hukseflux Modbus registers are available with an offset in the register address.
6.1 PC communication: Sensor Manager software
The digital SR05 series can be accessed via a PC. In that case the communication with
the sensor is done via the user interface offered by the Hukseflux Sensor Manager
software or by another Modbus testing tool. The Sensor Manager can be downloaded by
the user via www.hukseflux.com/downloads. Alternatively, there are links to testing
tools, paid or freeware, available at www.modbus.org.
This chapter describes the functionality of the Sensor Manager only.
The Hukseflux Sensor Manager software provides a user interface for communication
between a PC and SR05. It allows the user to locate, configure and test one or more
SR05’s and to perform simple laboratory measurements using a PC. The Sensor
Manager’s most common use is for initial functionality testing and modification of the
SR05 Modbus address and communication settings. It is not intended for long-term
continuous measurement purposes. For available software updates of the Sensor
Manager, please check www.hukseflux.com/downloads.
6.1.1 Installing the Sensor Manager
Running the Sensor Manager requires installation of the latest version of Java Runtime
Environment software. Java Runtime Environment may be obtained free of charge from
www.java.com. The SR05 specifications overview (Table 3.1.1) shows the system and
software requirements for using a PC to communicate with SR05.
1) Download the Hukseflux Sensor Manager via www.hukseflux.com/downloads.
2)
Unzip the downloaded files and copy the folder “Hukseflux Sensor Manager” to a
folder on a PC. For proper installation the user should have writing rights for
this file location.
3)
Double-click “Hukseflux_Sensor_Manager.jar” in the folder “Hukseflux Sensor
Manager”. This will start up the Sensor Manager.
