Introduction

• 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, etc.
• A voltage-free contact input allows connecting a rain gauge with contact output. 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 simultaneous 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 the 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, through 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, and 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.
• 35 mm DIN rail installation.

Connections

POWER SUPPLY

RS485 MODBUS-RTU CONNECTION

• Thanks to the RS485 connection, several sensors can be connected in a multi-point network.
• 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 characteristics. Typically, the maximum length is 1200 m. The data line must be kept separated from any power lines to avoid interferences to the transmitted signal.
• Each sensor in the RS485 network is univocally identified by an address ranging between 1 and 247. No more than one sensor with the same address can be present in the network.

RAIN GAUGE CONNECTION

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, the Windows® operating system automatically recognizes the instrument as an HID device (Human Interface Device) and uses the drivers already included 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 proprietary (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 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 the 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.

Software

• The parameters of the instrument (logging parameters, alarm thresholds, quantities to be acquired, network settings, etc.) can be configured by connecting the instrument to the PC via USB or Ethernet local network and using the HD35AP-S.
  Some basic parameters (alarms, logging interval, user code, …) can also be set with the HDServer1 application software.
• Both software can be downloaded from the website.
• To download the data in a database, the HD35AP-S (it allows connecting one data logger at a time) or HDServer1 (it allows connecting several data loggers simultaneously) application software and the MySQL database management system (included in the application software 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 configuration in response to FDA 21 CFR part 11 recommendations.

In particular, become available:

• The traceability of activities (Audit Trail) performed with the software; for example, which users connected and what changes were possibly made to the configuration of the instrument.
• The management of the user’s access to 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 standard User); for each level, the allowed operations can be defined.
• The HD35AP-CFR21 option works with a USB hardware key to be connected to any PC connected to the same local network of the PC in which the basic software is installed.

Modbus

The device’s 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:

• Type: b = bit, B = 8 bits (Byte), W = 16 bits without sign (Word), SW = 16 bits with sign
• (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).
• (x100) = centesimal value expressed as an integer (e.g., if the content of the register 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.
