1. INTRODUCTION

EVD Web is a gateway with Ethernet connectivity and data logging functions which allows users to remotely monitor and control up to 19 EVCO devices with EPoCA® technology using the EPoCA® cloud platform. It has been designed for use in the Ho.Re.Ca, refrigeration or air conditioning sectors. EVD Web can also send the current time to controllers which do not have a real time clock.

Equipped with 3 RS-485 master serial ports, each for a line of up to 6 controllers with the MODBUS RTU protocol, EVD Web also has a TTL serial port to connect another EVCO controller. Its three additional analogue inputs can be used for temperature sensors, which are also useful as a redundant detection system.
Data from controllers in the network can be shared with third-party supervision systems using the MODBUS TCP protocol. Systems of this kind can be used to gain information or interact with the machinery and can operate alongside EPoCA®.

If third-party controllers are among the devices connected to EVD Web, the network controlled by EVD Web can be managed exclusively with the MODBUS TCP protocol. It is possible to connect controllers of different parties, even if they have incompatible communication parameters, as each of the three RS-485 ports can be configured separately.

3. MEASUREMENTS AND INSTALLATION

3.1 Measurements

Measurements are expressed in mm (inches).

3.2 INSTALLATION

On a DIN rail in a control panel. To install the device, proceed as shown in figures 1 and 2.

To uninstall the device, first remove any plug-in screw terminal blocks at the bottom then proceed as shown in figures 3 and 4.

Before re-installing the device, press the clip fully in.

INSTALLATION PRECAUTIONS

– ensure that the working conditions are within the limits stated in the TECHNICAL SPECIFICATIONS section
– do not install the device close to heat sources, equipment with a strong magnetic field, in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or shocks
– in compliance with safety regulations, the device must be installed properly to ensure adequate protection from contact with electrical parts. All protective parts
must be fixed in such a way as to need the aid of a tool to remove them

4. DESCRIPTION

5. ELECTRICAL CONNECTION

CAUTION
– use cables of an adequate section for the current running through them
– each of the power supplies of the controllers connected to the RS-485 networks must be galvanically isolated from the others
– to reduce any electromagnetic interference, connect the power cables as far away as possible from the signal cables and connect the RS-485 networks using a twisted pair
– the maximum number of controllers that may be connected to each RS-485 network is 6
– the compatibility of the connected controllers with the EPoCA® cloud platform depends on the type of controller: see the document EPoCA – List of compatible controllers which is available on the website www.evco.it or by scanning the QR code below:

– if the device is moved from a cold to a warm place, humidity may cause condensation to form inside. Wait for about an hour before switching on the power
– make sure that the supply voltage, electrical frequency and power are within the set limits. See the section TECHNICAL SPECIFICATIONS
– disconnect the power supply before carrying out any type of maintenance
– do not use the device as a safety device
– for repairs and further information, contact the EVCO sales network

6. MAIN POSSIBLE SCENARIOS

6.1 Scenario 1

Management via the EPoCA® cloud platform of:

– up to 18 EVCO devices with EPoCA® technology connected in 3 RS-485 networks:
– 6 connected to the first RS-485 MODBUS master port
– 6 connected to the second RS-485 MODBUS master port
– 6 connected to the third RS-485 MODBUS master port
– 1 device with EPoCA® technology connected to the TTL MODBUS port
– up to 3 analogue inputs (virtual devices)

Devices in the network can also be managed in parallel by a third-party supervision system which uses the MODBUS TCP protocol.

6.2 Scenario 2

Management via a third-party supervision system which uses MODBUS TCP of:

– up to 18 EVCO or third-party devices with the MODBUS RTU protocol:
– 6 with the same connection parameters (baud rate, parity, stop bits) connected to the first RS-485 MODBUS master port
– 6 with the same connection parameters (baud rate, parity, stop bits) connected to the second RS-485 MODBUS master port
– 6 with the same connection parameters (baud rate, parity, stop bits) connected to the third RS-485 MODBUS master port
– 1 EVCO device connected to the TTL MODBUS port
– up to 3 analogue inputs (virtual devices)

In the example in the figure below:

– 6 devices with EPoCA® technology are connected to the first RS-485 network
– 6 devices with EPoCA® technology are connected to the second RS-485 network
– 6 third-party devices are connected to the third RS-485 network
– 1 EVCO device is connected to the TTL MODBUS port.

7. FIRST-TIME USE

N.B.
– Users will need a PC (or laptop) which has the Windows 10 or later operating system installed, a free USB port, a web browser installed and Internet access
– Make sure there is a router with Internet access and that the router has a free Ethernet port. Alternatively, make sure there is a free Ethernet port in an Ethernet hub connected to a local network. If a third-party supervision system is used, rather than the EPoCA® cloud platform, it must be installed on a PC or laptop which is connected to the same Ethernet network as EVD Web and the EVD Web IP address must be static.

7.1 First-time use of EVD Web

1. When configuring the networks of EVCO devices connected to EVD Web, the procedure depends on whether they have or do not have EPoCA® technology: – if the EVCO device does not have EPoCA® technology, parameter LA (MODBUS address) must be set as shown in the table below. The remaining connection parameters of the devices connected to the same port must all be the same.

– if the EVCO device has EPoCA® technology, parameter bLE (EPoCA® local network address) which automatically configures the other connection parameters (19200 baud rate, even parity) must be set as shown in the table below. The setting of parameter LA (MODBUS address) in these devices is not relevant and
does not affect network configuration.

2. Disconnect power from each device and then reconnect it again.
3. Carry out the installation of EVD Web as shown in the section MEASUREMENTS AND INSTALLATION.
4. Connect the power supply, analogue inputs, RS-485 MODBUS master ports and TTL MODBUS port of EVD Web as shown in the sections ELECTRIC CONNECTION and MAIN POSSIBLE SCENARIOS without powering it up.
