MODULE LAYOUT
Weight: 80g; Enclosure: UL94-V0 self-extinguishing PC/ABS material, black.
SIGNALS VIA LED ON FRONT PANEL
| LED | STATUS | LED meaning |
|---|---|---|
| PWR | On | The device is powered with assigned IP |
| Flashing | IP not assigned | |
| TX | Flashing | Data transmission on port RS232/RS485 |
| RX | Flashing | Data receipt on port RS2321RS485 |
| ETH ACT (Yellow) | Flashing | Packet transit on Ethernet port |
| ETH LNK (Green) | Flashing | Ethernet port connected |
| COM (R-KEY-LT-P version only) | Flashing | Profinet communication active |
| Off | No Profinet communication | |

active
DEVICE CONFIGURATION
The device can be fully set up via an integrated webserver. 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
WEB SERVER AND PROFINET MODE (R-KEY-LT-P)
The device is normally in Profinet mode; in Profinet mode the device can be
configured only through the Easy Setup 2 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
following the procedure:
To force webserver mode:
- Keep the “REBOOT / MODE” button pressed until all the LEDs flash quickly
- Release the button
- The device restarts and the PWR and COM LEDs flash slowly to indicate webserver mode To force Profinet mode:
- Keep the “REBOOT / MODE” button pressed until all the LEDs flash quickly
- Release the button
- The device restarts and the PWR and COM LEDs stop flashing slowly to indicate Profinet mode
WEBSERVER
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 aluminum or AL-CU or CU-AL conductors
| POWER SUPPLY | RS485 SERIAL PORT | RS232 SERIAL PORT |
|---|
The power supply source must be protected from any module malfunctions using appropriately-sized safety fuses.
| |
CAUTION
The device can only be powered by a power supply with a limited energy circuit
40Vdc / 28Vac max in the 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.
