DEVICE CONFIGURATION
The device can be fully set up via integrated web server. The product programming and/or configuration tools, as well as all the manuals, can be downloaded using the QR-CODE from the web address: For further information, refer to the USER MANUAL.
FACTORY IP ADDRESS
The default module IP address is static: 192.168.90.101
PROFINET AND WEBSERVER MODE
The device is normally in Profinet mode; in Profinet mode the device can be configured only through the Easy Setup2 software.
In order to access the internal webserver it is necessary to put the device in Webserver mode using the Easy Setup2 or Seneca Device Discovery software. it is also possible to change the operating mode by pressing the side button PS1 following the procedure given in the user manual.
WEB SERVER
To access the maintenance Web Server with the factory IP address above, use the following credentials:
Username: admin; Password: admin
N.B.: For the R-KEY-LT-P version it is first necessary to activate webserver mode
CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

ELECTRICAL CONNECTIONS
CAUTION
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc…).
CAUTION
Use only copper or copper-coated aluminium or AL-CU or CU-AL conductors
CAUTION
The device can only be powered by a power supply with a limited energy circuit 40Vdc / 28Vac max in output according to CAN/CSA-C22.2 No.61010-1-12 / UL Std.No.61010-1 (3rd Edition) chapter 6.3.1/6.3.2 and 9.4 or class 2 according to CSA 223/UL1310.
CAUTION
These are open type devices intended for installation in a final casing/panel that offers mechanical protection and protection against the spread of fire.
