Page 5: General Description
GENERAL DESCRIPTION Rilheva platform is an innovative solution that gathers all your hardware data and transmits • them to a control and monitoring server, through a platform integrating hardware, software and services. Rilheva II is an electronic device able to capture data through the serial ports RS232, RS485 and • Ethernet using ModBus RTU / Modus TCP protocol and send them, via GPRS/3G modem or xDSL line, to Xeo4 Cloud servers. Here your data are stored, processed and made available to the authorized users by using a common internet browser or a smartphone app. This way, Rilheva II allows to monitor and control your remote sites without the necessity to • build your own control center. The user has only to browse the internet, access to www.rilheva.it portal and authenticate • himself in order to monitor and control all the data available on the remote site, in the same way as he was there. The Rilheva II device implements internally the master Modbus protocol, able to query up to 31 • slave devices with a polling frequency up to 1 second. The device analyzes the received data (with a maximum of about 1000 variables) and send them to the Xeo4 servers. This can be done on a polling basis (user settable) or instantaneously when alert events are triggered. All the data and parameters are made available online through the Rilheva portal, where it is • possible: Configure the registers for every slave device View all the registers in real time View or extract historical data, trends, diagrams, analytical and summary reports Set the value for a register parameter (output, set-point) Build a standard configuration template (model) to be reloaded in the future Access the diagnostics section to investigate any communication issue... -

Page 14: Device Configuration Via Sms
DEVICE CONFIGURATION VIA SMS For the Rilheva device being fully operating, it has to be correctly configured. The following operations must be executed: Enter a valid SIM card (having GPRS service 2G/3G enabled) into the dedicated slot while the device is powered off. Important: make sure that the PIN code is disabled for the SIM card used with Rilheva. If not, insert the SIM card into a GSM phone and follow the procedure to disable the PIN, ensuring that it will not be requested anymore. Important: please disable all value added services that might be provisioned from your mobile operator and that may cause the sending of SMS messages to the SIM Cards. 2) Power-up the device After few seconds, the 3 LEDs will blink at the same time, indicating that the device is waiting for the first configuration (e.g. configuration SMS message or web settings). 3) You can send an SMS configuration message to the device (using the SIM number installed) this way: A**[IMEI code]**[cloud server host/IP]**[cloud server port] **[provider APN]** [username]**[password] this serial code (15 digits) is printed on the device [IMEI code] label [cloud server host/IP] engine2.xeo4.it [cloud server port] 8081 depending on the GSM provider, the suggested APN must be specified.

Page 20: Configuration Page
CONFIGURATION PAGE This screen allows to configure the main settings required to perform the startup of the Rilheva device. It is possible to assign different IP addresses to the two LAN ports (eth0 and eth1). The eth0 port can be configured either for the automatic acquisition of an IP address (via DHCP) or statically. In the GPRS/3G section the APN parameter can be defined depending on the GSM operator chosen, and username/password (only if required, otherwise leave the field empty). Using the “Wan interface” setting, it is possible to choose the way the device will connect to the Internet, and so to the Rilheva Cloud system. By choosing “LAN eth0” choice, the device will use the parameters of this section in order to connect to the Internet. On the other hand, by choosing “GPRS/3G” the device will use the installed SIM card to connect to the mobile network. -

Page 22: Diagnostic Leds Meaning
DIAGNOSTIC LEDS MEANING FIRST CONFIGURATION If the device is not configured initially, the three LEDs will be simultaneously blinking, to indicate that the device is waiting for receiving the configuration SMS or the first web configuration. This initial configuration can also be obtained by performing a device factory reset. NORMAL OPERATION During normal working operation, LEDs must have the following status: LED STATUS > green blinking LED NET > red fixed on LED FIELD > off with short blinks during Modbus polling activity MALFUNCTION INDICATIONS Led STATUS solid orange If the STATUS led is solid orange, an hardware error has occurred. Please contact Technical Support. Led STATUS blinking orange/red alternately In this case, the device is polling the slave devices via Modbus protocol, but some reading errors persist. Led FIELD solid red If the FIELD led is solid red, the Rilheva device is not communicating correctly with the Modbus devices. Led NET blinking fast (about 10 flashes/sec) This indication tells that a severe hardware error is present. Please contact Technical Support. Led NET blinking slow (about 2 flashes/sec) In this case, there can be some problem with the SIM card. Please check that SIM card is active, properly installed into the slot and with PIN lock feature disabled. -
Page 23: Factory Reset Procedure
FACTORY RESET PROCEDURE In order to restore the factory conditions of the Rilheva, it is necessary to power up the device keeping the pinhole [R] pushed with a pin or paper clip, waiting until the three LEDs will start blinking sequentially (wait for about 20 seconds). At this point, just wait 5 seconds more until the led sequence will stop and release the [R] button. The device will reboot showing the three LEDs simultaneously blinking (see “first configuration”). -

Page 25: Modbus Features
MODBUS FEATURES Serial ports (Modbus RTU) The physical communication line is compliant with EIA-RS485 standard (2 wire half-duplex mode). For Modbus communication, it is also possible to use the RS232 port (P2P mode). For Modbus, protocol RTU (Remote Terminal Unit)will be used. The serial baudrate can be selected among: 1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps, 28800 bps, 38400 bps, 56000 bps, 57600 bps, 115200 bps The RTU byte is composed by 11-bit: 1 start bit • 8 data bit • 1 parity bit (NONE, ODD, EVEN) • 1 or 2 stop bit (2-if parity is set to NONE) • Ethernet port (Modbus TCP) It is possible to connect Modbus TCP devices to the ethernet ports eth0 and eth1. The network configuration (device IP and subnet) has to be initially set by using the integrated web server. -

Page 29: Guidelines For Rs-485 Bus Connection
GUIDELINES FOR RS-485 BUS CONNECTION RS-485 standard RS-485 standard is based on a balanced signals system. This means that two signals are ideally one opposed to each other, respect to the ground. It is strongly suggested that the transmission line will be formed by a “twisted pair” cable. This kind of cable is particularly immune to electromagnetic noise. Transmission cable In order to prevent any interference risks, a properly shielded cable should always be used, especially if you are close to power signals (e.g. electric engines, inverters, relais). We recommend to use cat. 5E cable or equivalent. Generally speaking, the RS-486 transmission cable should be shielded and compliant to the following specifications: Cable capacity <=300pF/m • Line impedance 100 Ω ±15 Ω • Line resistance 140 Ω/km or 225 Ω • Cable type: copper twisted pair • Network connection As far as possible, limit the RS-485 network to a main single line (one segment) • Limit the total length of the main line to a maximum of 1000 m • Do not connect more than 31 devices on the same RS-485 segment • Disconnect the line termination resistors (if any) on all the slave devices connected • For short networks (up to 30 m) no line termination resistor is needed • For more extended networks, it could be necessary to terminate the RS-485 line in the • following way:... -
Page 30: Configurations To Avoid
Position a 120 Ohm resistor at the line end (after the last slave device, or directly on the device itself) Configurations to avoid RS-485 networks implement a so-called “daisy chain” configuration. This means that a single main line (cable) exists and all the devices are directly connected along the line path. By using other kinds of connection (e.g. star point, T branching), you cannot be guaranteed about the good functionality of the network, especially if electromagnetic noise is present or for long networks or high number of connected nodes. -
Page 31: Grounding
Grounding Be sure that all the devices will use the same ground, especially if using more than one power supply. The RS485 line shield should be grounded only to a single line end. RS-485 bus polarization For the RS-485 bus to be working correctly, it is necessary that electric signals are polarized in a proper way. When all the Modbus slave devices are listening and the master device (namely Rilheva) is not polling (transmitting), the RS-485 bus will remain in high-impedance status. In this situation, sometime, the RS-485 bus may be interfered by some external electromagnetic noise that could be interpreted as real signals by the listening stations. You can check whether the RS-485 bus is polarized properly by using a common tester (digital multimeter) and measuring the voltage between the terminals + and – (while no traffic exists on the bus) and verifying that the voltage is greater than 200 mV. If not, you should connect two polarization resistors: one between terminal + (B) and terminal VEXT (+) • one between terminal – (A) and terminal VEXT (C) •... - Page 32 In order to calculate the Rb resistor value, we have to bear in mind that they must maintain a voltage of about 200 mV when all the devices are listening. Let’s do an example on how to find the Rb resistance value. We suppose to be in the following situation: The bus is composed by 32 nodes with input impedance equal to 12KΩ • Two termination resistors (120Ω) are present • Supply voltage is 5 VDC • We say Zo the impedance made by the parallel of 2 termination resistors (120Ω) and 32 input impedance of the devices (12kΩ), whose result is about 52Ω; and we say E the power voltage for the bus polarization (5V) Rb is calculated by the following formula: In this case the value is about 620 Ω. This polarization network must be connected in a single point of the bus, possibly close to the master device (Rilheva II).
