Remote supervision
- Internet: client and server use internet to communicate. The server must have a unique static IP address
which identifies it: this address must be specified in the Address field. The client must already have connected
to internet before connecting to the server, or RICS will connect with the internet provider using the
connection name specified in the General settings, Internet connection field (this can be accessed on
Main menu>Connection>Settings)
- Username and Password: these fields represent the username and password of a user profile on the RICS
server (e.g.: INSTALLER) on which the Enable Remote access checkbox was selected in RICS
Options Page:
• Behaviour: Defines the purpose of the connection to the server. There are two possible types of behaviour:
- Browse the remote system: once connected this displays an image of the remote station; it shows the
classic RICS interface upon which you can interact with the devices
- Only perform download: After the download of the specified files, the client disconnects from the remote
server (this option can be useful, for example, when you only want to download the data history and then
analyse it off-line).
• Download: the files to be downloaded are specified. Amongst the possible file types are the following:
- Configuration: RICS server station configuration file. You are advised to always download these files. The
first time you connect you must download these files.
- History: files containing system server data. To allow the download the item that allows the download of
general historical data must be selected (in Connection>Configure).
• Server directory name: name of the directory (folder) where server files and settings are saved (by default
this is the name in the Logical name field). Just like the logical name, this field, too, must be unique, and
no connections can exist to distinct servers that have the same directory. This would lead to conflicting data.
RICS client can show distinct images of several server stations (e.g. device images, wallpaper images etc… ).
It only makes sense to share the same directory with different servers if they represent a connection to the
same station. This can occur when, for example, the servers are split logically because the connection
methods used by clients to access the servers are different.
Advanced page: you are advised to modify the contents of this page ONLY if you are an expert user. This page
allows the modification of parameters for the following services:
• FTP: In FTP services you can specify the Port in which the RICS server offers those services (the default is
2121) and whether the FTP connection is passive or not. If the server is located on a company network
protected by a firewall it may be necessary to enable the passive mode and ensure that port 2121 in the
firewall has been enabled on the server side; if the connection fails, you are advised to set the port (both on
the client and server) to 21, ensuring that the firewall on the server side has enabled port 21 (you will also
have to disable any eventual Windows FTP Services that use those ports, or ensure that those services use a
different port number to avoid possible conflicts).
• EDCS: this represents the protocol implemented by RICS for client/server communication in a TCP channel.
You are advised to leave the port on the default settings, both on the client and the server, or more precisely
Port 2345; in this case, too, if it crosses a firewall, the firewall must enable that port.
14.5.2 Connection within a LAN: an example
This section shows how to ensure a client/server RICS connection when both systems are on PCs in the same company
network.
In the example the following assumptions have been made:
• SERVER:
- Is a PC on a company network
- The LAN IP address is:130.164.0.88.
• CLIENT:
- is a PC on the same company network
- the LAN IP address is: 130.164.0.124.
