HD50 - 3 - V1.0

1INTRODUCTION

The HD50R-MB data logger allows several physical quantities to be monitored in a

large variety of application fields.

To the “Master” RS485 MODBUS-RTU input you can connect a network of sensors for

measuring, for example, temperature, humidity, atmospheric pressure, solar radiation,

wind speed and direction (e.g. an anemometer of the HD52.3D… series can be con-

nected), etc.

As an alternative to the Modbus-RTU protocol, a proprietary protocol can be used to

connect the HD2003 anemometer.

A voltage-free contact input allows connecting a rain gauge with contact output. Rain

gauges with contact output either normally closed or normally open can be connected.

A measurement compensation curve as a function of the rainfall rate can be config-

ured. The data logger calculates the rainfall rate in mm/h (by referring the rainfall

quantity in the last five minutes to an hourly value) and the rainfall quantity in the

last day.

The data logger can be connected to an Ethernet local network and allows the simul-

taneous operation of two communication protocols: proprietary and Modbus TCP/IP.

The data logger manages up to 10 “TCP/IP Client” simultaneously. If the local network

is connected to Internet, the data can be regularly sent to an FTP address, to the

Cloud and via e-mail.

For each detected quantity, two alarm thresholds can be set by the user. Exceeding a

threshold is signaled acoustically, by means of the internal buzzer, and remotely, by

sending alarm e-mails. An alarm hysteresis and a delay in the generation of the alarm

can be configured for each detected quantity.

The PC software HD35AP-S allows configuring the data logger, viewing the real time

measurements, downloading and viewing the data into a database. The HD35AP-S

software allows connecting one data logger at a time. If there are several data loggers

in the local network, the PC software HDServer1 allows detecting automatically all the

data loggers connected to the network and connecting simultaneously to all the data

loggers; it also allows entering the data received by the data loggers into a database,

viewing the data in the database and configuring the main measurement parameters

of the devices (alarms, logging interval, …). The HD35AP-CFR21 software option

(available with both HD35AP-S and HDServer1) allows the protection of recorded data

and configuration in response to FDA 21 CFR part 11 recommendations.

RS485 MODBUS-RTU CONNECTION

Thanks to RS485 connection, several sensors can be connected in a multi-point net-

work. The instruments are connected in sequence by means of a shielded cable with

twisted pair wires for signals and a third wire for the ground.

The RS485 ground is isolated from the power supply.

Line terminations must be placed at the ends of the network. If the instrument is at

one end of the line, insert the termination placing the short jumper next to the RS485

connector between the “RT” and “CLOSE” indications. Otherwise, remove the termina-

tion placing the short jumper between the “RT” and “OPEN” indications.

The cable shield must be connected to both ends of the line.

The cable maximum length depends on the transmission speed and on the cable char-

acteristics. Typically, the maximum length is 1200 m. The data line must be kept se-

parated from any power lines to avoid interferences to the transmitted signal.

Each sensor in the RS485 network is univocally identified by an address ranging within

1 and 247. No more than one sensor with the same address can be present in

the network.

USB CONNECTION

The data logger can be connected to a PC via the mini-USB connector and the CP23

cable.

USB connection doesn’t require the installation of drivers: when the data logger is

connected to a PC, Windows® operating system automatically recognizes the instru-

ment as an HID device (Human Interface Device) and uses the drivers already in-

cluded in the operating system.

ETHERNET CONNECTION

Connect the RJ45 connector of the data logger to a socket of the local network via a

standard Ethernet cable.

The data logger is preset to get a dynamic IP address from the network DHCP server.

The IP address can be displayed and changed by connecting the data logger to a PC via

USB and using the HD35AP-S application software. A static IP address can also be set.

The IP address can also be displayed by connecting the data logger to a PC via Ethernet

and using the HDServer1 software, which can automatically detect the data loggers

connected to the network.

Thanks to the availability of two TCP/IP ports, each of which can operate with proprie-

tary (for the connection with HD35AP-S software) or MODBUS TCP/IP protocol, and

ten sockets (in total, to be divided between the two ports), the data logger allows the

Rain gauge contact

simultaneous operation of two communication protocols (proprietary and Modbus

TCP/IP) and manages up to 10 “TCP/IP Client” simultaneously. The default setting of

the ports is the following:

•Port number = 5100 for proprietary protocol (8 sockets)

•Port number = 502 for Modbus TCP/IP protocol (2 sockets)

The Ethernet settings can be changed with the HD35AP-S software. It is possible to

restore the factory parameters by placing the short jumper next to the NET RST

push-button between the “2” and “3” indications and then pressing the NET RST

push-button. After the reset, replace the short jumper between the “2” and “1 (NOR-

MAL)” indications.

If the local network is connected to Internet, the data can be regularly sent to an FTP

address, to the Cloud and via e-mail (as attachments).

Note: if the communication with the Cloud is used, the maximum number of “clients”

with proprietary or MODBUS TCP/IP protocol is nine.

4SOFTWARE

The parameters of the instrument (logging parameters, alarm thresholds, quantities

to be acquired, network settings, etc.) can be configured by connecting the instru-

ment to the PC via USB or Ethernet local network and using the HD35AP-S applica-

tion software (see the instructions of the software).

Some basic parameters (alarms, logging interval, user code, …) can also be set with

the HDServer1 application software.

To download the data in a database, the HD35AP-S (it allows connecting one data log-

ger at a time) or HDServer1 (it allows connecting several data loggers simultaneously)

application software and the MySQL database management system (included in the

application softwares packages) must be installed.

HD35AP-CFR21 SOFTWARE OPTION

The HD35AP-CFR21 option allows, in addition to the features of the basic software

(both HD35AP-S and HDServer1), the protection of recorded data and instrument con-

figuration in response to FDA 21 CFR part 11 recommendations. In particular be-

come available:

•The traceability of activities (Audit Trail) performed with the software; for exam-

ple, which users connected and what changes were possibly made to the configu-

ration of the instrument.

•The management of users access for the instrument configuration and viewing of

data in the database. Each user can be assigned a different password for using the

software. There are also three levels of access (Administrator, Super-user and stan-

dard User); for each level, the allowed operations can be defined.

The HD35AP-CFR21 option works with USB hardware key to be connected to any PC con-

nected to the same local network of the PC in which the basic software is installed.

The device general information can be read through the function code 0x2B/0x0E:

•Manufacturer (Delta OHM)

•Model

•Firmware version

The list of MODBUS registers is shown below. Depending on the connected sensors,

some of the registers could not be significant for the system.

The following conventions have been used in the tables:

oType: b= bit, B= 8 bits (Byte), W= 16 bits without sign (Word), SW = 16 bits

with sign

o(x10) = decimal value expressed as an integer (e.g., if the content of the register

is 184, the value is to be intended as 18,4).

o(x100) = centesimal value expressed as an integer (e.g., if the content of the reg-

ister is 500, the value is to be intended as 5,00).

The commands for requesting units of measurement return an index according to the

correspondence indicated in the table below:
