DESCRIPTION
The R series is based on devices equipped with two Ethernet switch ports that allow a chain connection to the
next Ethernet device (daisy chain), so expensive industrial Ethernet switches are not required and wiring is
simplified.
The hardware present in the devices allows the internal switch to work even if the device is faulty or not
powered for up to 4 days (LAN function with bypass in case of failure).
Another important function is the possibility of copying inputs on remote outputs of R series products without
the aid of a master device (peer 2 peer function) (only for R-32DIDO version).

CONNECTION OF THE DEVICES TO A NETWORK (ONLY R-32DIDO MODEL)
CONNECTION OF THE DEVICE TO A NETWORK
The factory configuration of the IP address is:
Static address: 192.168.90.101
Therefore, multiple devices must not be inserted on the same network with the same static IP.
If you want to connect multiple devices on the same network, you need to change the IP address configuration
using the Easy Setup 2 software.
ATTENTION!
DO NOT CONNECT 2 OR MORE FACTORY-CONFIGURED DEVICES ON THE SAME NETWORK, OR THE
ETHERNET INTERFACE WILL NOT WORK
(192.168.90.101 IP ADDRESS CONFLICT)
If the addressing mode with DHCP is activated and an IP address is not received within 1 minute, the device will
set an IP address with a fixed error:
169.254.x.y
Where x.y are the last two values of the MAC ADDRESS.
This way it is possible to install more I/O of the R series and then configure the IP with the Easy Setup 2
software even on networks without a DHCP server.
USING EASY SETUP 2 TO CONFIGURE DEVICES
The Easy Setup 2 software allows:
▪Configuring R series devices via the USB port
▪Searching and configuring Seneca R-series devices on an Ethernet network
In the case of a first installation we recommend following these steps:
1) Install the Easy Setup 2 software
2) Power and connect the device to the PC via the USB port

3) Configure the device with the IP address and the desired configuration
4) Install the device
If many devices are installed using the USB port:
1) Power and connect the device to the PC via the USB port
2) Configure the automatic address via DHCP from the search window
3) Install all the devices in the network
4) If there is no DHCP server in the network, after 1 minute the devices will set a fail IP address (see
chapter 2.1)
5) Wait for all the device STS LEDs to be on steady.
6) At this point, using Easy Setup 2, create a new Ethernet project and find all the devices with the
"search" button, then reconfigure the devices with the most appropriate work addresses.
In case of many devices using the Ethernet port:
1) Power and connect the first device to the PC via the Ethernet port
2) Perform the search
3) Change the address of the device with IP 192.168.90.101 from the search window
4) Connect the second device in Daisy Chain, search and return to step 2) until all devices are configured
The search software included in Easy Setup 2 works at Ethernet Layer 2 level (through the Seneca Discovery
protocol) and it is therefore not necessary to have an Ethernet configuration compatible with the device you are
looking for to change its IP. For the general configuration of the device it is necessary to have compatible
configuration.

I/O COPY USING THE PEER TO PEER FUNCTION WITHOUT WIRING (ONLY R-
32DIDO MODEL)
The "R" series devices can be used to copy and update in real time an input channel on a remote output
channel without the aid of a master controller.
For example, a digital input can be copied to a remote digital output device:
Note that no controller is required because the communication is managed directly by the R series devices.
It is possible to make a more sophisticated connection, for example it is possible to copy the inputs to different
R-series remote devices (from Device 1 Input 1 to Device 2 Output1, Device 1 Input 2 to Device 3 Output 1 etc
...)
It is also possible to copy an input to an output of multiple remote devices:
Each R-series device can send and receive a maximum of 32 inputs.
For further information, see chapter 5.2.4.

MODBUS PASSTHROUGH (ONLY R-32DIDO MODEL)
Thanks to the Modbus Passthrough function it is possible to extend the amount of I/O available in the device via
the RS485 port and the Modbus RTU slave protocol, for example by using the Seneca Z-PC series products.
In this mode the RS485 port stops working as Modbus RTU slave and the device becomes a Modbus TCP-IP
gateway to Modbus RTU serial:
Each Modbus TCP-IP request with station address other than that of the R series device is converted into a
serial packet on the RS485 and, in the case of a reply, it is turned over to TCP-IP.
Therefore, it is no longer necessary to purchase gateways to extend the I/O number or to connect already
available Modbus RTU I/O.

WEBSERVER (ONLY R-32DIDO MODEL)
ACCESS TO THE WEB SERVER
Access to the web server takes place using a web browser and entering the IP address of the device.
To find out the IP address of the device, use the "search" function of the “Easy Setup 2" software (see chapter
10).
On first access the user name and password will be requested.
The default values are:
User Name: admin
Password: admin
ATTENTION!
AFTER THE FIRST ACCESS CHANGE USER NAME AND PASSWORD IN ORDER TO PREVENT
ACCESS TO THE DEVICE TO UNAUTHORIZED PEOPLE.
ATTENTION!
IF THE PARAMETERS TO ACCESS THE WEB SERVER HAVE BEEN LOST, IT IS NECESSARY TO
RESET THE FACTORY-SET CONFIGURATION (SEE CHAPTER 7)

DIGITAL I/O SETUP SECTION
This section allows the configuration of the digital I/Os present in the device.
DIGITAL I/O MODE (default Input)
Selects whether the selected input will work as an input or output.
DIGITAL INPUT NORMALLY HIGH/LOW (default Normally Low)
If selected as digital input, it configures whether the input is normally high or low.
DIGITAL OUTPUT NORMALLY STATE (default Normally Open)
If selected as digital output, it configures whether the output is normally open or closed.
DIGITAL OUTPUT WATCHDOG (default Disabled)
If selected as digital output, it sets the output watchdog mode.
If “Disabled”, it disables the watchdog function for the selected output.
If "Enabled on Modbus Communication" the output goes into "Watchdog state" if there has been no generic
Modbus communication within the set time.
If "Enabled on Modbus Digital Output Writing" the output goes into "Watchdog state" if there has been no writing
of the output within the set time.
DIGITAL OUTPUT WATCHDOG STATE (default Open)
Sets the value that the digital output must adopt if the watchdog has been triggered.
DIGITAL OUTPUT WATCHDOG TIMEOUT [s] (default 100s)
Represents the watchdog time of the digital output in seconds.

P2P CONFIGURATION
In the P2P Client section it is possible to define which local events to send to one or more remote devices.
This way it is possible to send the status of the inputs to the remote outputs and obtain the input-output replication
without wiring. It is also possible to send the same input to several outputs simultaneously.
In the P2P Server section it is instead possible to define which inputs must be copied to the outputs.
The "Disable all rules" button places all the rules in a disabled status (default).
The "APPLY" button allows you to confirm and then save the set rules in the non-volatile memory.

PORT parameter of the remote device.
En
Selects operation in "Only Timed" or "Timed+Event" mode.
In "Only Timed" mode, the status of the inputs is sent on each "tick [ms]" and then refreshed continuously (cyclic
sending).
In the “Timed+Event” mode, the status of the inputs is sent to a digital event (change of status).
Tick [ms]
Sets the cyclical sending time of the input status.
ATTENTION!
IN CASE OF ENABLED WATCHDOG OF DIGITAL OUTPUTS THE RULE'S TICK TIME MUST BE LOWER
THAN THE WATCHDOG TIMEOUT SET
ATTENTION!
IT IS ALSO POSSIBLE TO COPY SOME I/O OF THE SAME DEVICE (FOR EXAMPLE, COPY THE I01
INPUT TO D01) BY ENTERING THE IP OF THE DEVICE AS REMOTE IP
