2.2.1. PROTECTION OF DIGITAL OUTPUTS
The outputs are protected against overload and against overtemperature, they open cyclically until the fault is
repaired or the output opens.
The limit current is between 0.6 and 1.2 A.
2.2.2. I/O REACTION TIME
With an update time of the Profinet IO cycle set at 2ms (default) we obtain that:
The switching of a digital input is updated in the communication in maximum 4ms.
The command of a digital output via Profinet communication switches the output in maximum 4ms.
2.3. R-16DI-8DO-P
The devices allow the use of 16 digital input channels and 8 digital output channels (relay).

2.4.1. ANALOGUE INPUT UPDATE TIME
The sampling time of the analogue inputs depends on the ADC sampling time.
If an analogue input is disabled, its acquisition time must not be counted.
The refresh time of an analogue channel is:
󰇟󰇠 󰇛  󰇜  󰇛  
󰇟󰇠󰇜
Where:


󰇟󰇠󰆒
If, for example, the sampling time of the ADC is set at 50ms and all 8 input analogue channels are active, we
have:
T refresh = 9 * (2*50 +10ms) = 9*110ms = 990 ms
2.4.2. DIGITAL INPUT UPDATE TIME
The sampling time of the digital inputs takes place between the sampling of one channel and the other so the
I/O update takes place every:
󰇟󰇠 󰇛  
󰇟󰇠󰇜
If, for example, the sampling time of the ADC is set to 50ms, the refresh of the digital I/Os is:
T refresh = (2*50 +10ms) = 110ms

3. RESETTING THE DEVICE TO FACTORY CONFIGURATION
It is possible to reset the device to the factory configuration (factory IP address 192.168.90.101 included) using
the following procedure:
1) Remove power from the device
2) Depending on the model, if the dip switch is not directly accessible, remove the rear cover of the device
3) With the device off, set dip switch 1 and 2 to ON
4) Close the lid
5) Power up the device
6) The device has now been reset to the factory configuration
7) Turn dip switch 1 and 2 back to OFF.
4. CONNECTION OF THE DEVICE TO AN ETHERNET 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
(for instance using the Seneca Discovery Device software).
ATTENTION!
DO NOT CONNECT 2 OR MORE FACTORY-CONFIGURED DEVICES ON THE SAME NETWORK, OR THE
ETHERNET INTERFACE WILL NOT WORK
(CONFLICT OF IP ADDRESSES 192.168.90.101)
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 Seneca Discovery
Device software even on networks without a DHCP server.

ATTENTION!
BEFORE ACCESSING THE WEB SERBER, DISCONNECT THE DEVICE FROM THE PROFINET
NETWORK
The main purpose of the web server is to:
-Configure the Profinet name of the device without using an external development environment (Tia Portal,
Codesys,…)
-Allow the device firmware update
5.1. ACCESS TO THE WEB SERVER
Access to the web server takes place using a web browser and entering the IP address of the device.
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!

6.5. CONFIGURATION PARAMETERS OF THE GSDML FILE
6.5.1. R-32DIDO-P
SET DIGITAL IO INPUT/OUTPUT
Selects whether the selected input will work as an input or output.
SET DIGITAL INPUT NORMALLY HIGH/LOW
If selected as digital input, it configures whether the input is normally high or low.
SET DIGITAL OUTPUT NORMALLY OPEN/CLOSE
If selected as digital output, it configures whether the output is normally open or closed.
SET DIGITAL OUTPUT WATCHDOG
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 Profinet Communication" the output goes into "Watchdog state" if there has been no generic
Profinet communication within the set time.
SET DIGITAL OUTPUT WATCHDOG STATE
Sets the value that the digital output must adopt if the watchdog has been triggered.
SET DIGITAL OUTPUT WATCHDOG TIMEOUT [s]
Represents the watchdog time of the digital output in seconds. If the PLC stops communicating with the device
within the set time, then the outputs will go into the "Watchdog state" condition (if the function is enabled).
6.5.2. R-16DI-8DO-P
SET DIGITAL INPUTS FILTER DELAY [ms]
Sets the filtering of the counters, the value is expressed in [ms].
The filter cut-off frequency corresponds to:
[] = 1000/ (2   []
For example, if the filter counter is 100ms the cutting frequency will be:
[] = 1000/ (2   []) = 5 
So all input frequencies greater than 5 Hz will be cut.
SET ALL DIGITAL INPUTS NPN/PNP
Sets the input operating mode to between npn “Sink” and pnp “Source”
ENABLE DIGITAL OUTPUTS FAULT TIMEOUT

Set whether the digital output watchdog is to activated. When enabled, if within the timeout time there has been
no communication from the master to the device, the outputs go into a Fail state. This mode allows to obtain a
safe system in case of malfunction of the master.
SET DIGITAL OUTPUTS FAULT TIMEOUT [s]
Set the watchdog time of the digital outputs.
SET DIGITAL OUTPUT FAULT STATES OPEN/CLOSE
They set the states of each of the outputs under normal conditions.
SET DIGITAL OUTPUT NORMALLY OPEN/CLOSE
They set the states of each of the outputs in fail conditions.
6.5.3. R-8AI-8DIDO-P
SET DIGITAL IO INPUT/OUTPUT
Selects whether the selected input will work as an input or output.
SET DIGITAL INPUT NORMALLY HIGH/LOW
If selected as digital input, it configures whether the input is normally high or low.
SET DIGITAL OUTPUT NORMALLY OPEN/CLOSE
If selected as digital output, it configures whether the output is normally open or closed.
SET DIGITAL OUTPUT WATCHDOG
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 Profinet Communication" the output goes into "Watchdog state" if there has been no generic
Profinet communication within the set time.
SET DIGITAL OUTPUT WATCHDOG STATE
Sets the value that the digital output must adopt if the watchdog has been triggered.
SET DIGITAL OUTPUT WATCHDOG TIMEOUT [s]
Represents the watchdog time of the digital output in seconds. If the PLC stops communicating with the device
within the set time, then the outputs will go into the "Watchdog state" condition (if the function is enabled).
SAMPLING TIME
Set the sampling time of the selectable input between
50ms, or 100ms, or 200ms.
SET ANALOG MODE
