DESCRIPTION1.1.
The products Z-KEY-P, R-KEY-LT-P, Z-KEY-2TH-P autonomously read the registers of devices on a Modbus
serial/ethernet bus and make them available for access by a Profinet IO controller.
Each Modbus variable (tag) is converted to Profinet, a maximum of 500 variables (tags) can be defined.
The integrated webserver can be used to configure the device and for diagnostic purposes.
Below are the connection configurations of a classic use case:

ETHERNET PORT2.
The factory configuration of the Ethernet port is:
STATIC IP: 192.168.90.101
SUBNET MASK: 255.255.0.0
GATEWAY: 192.168.90.1
Multiple devices must not be inserted on the same network with the same static IP.
ATTENTION!
DO NOT CONNECT 2 OR MORE FACTORY-CONFIGURED DEVICES ON THE SAME NETWORK, OR THE
DEVICE WILL NOT WORK
(CONFLICT OF IP ADDRESSES 192.168.90.101)
WEBSERVER MODE AND PROFINET MODE3.
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 into 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 the webserver mode:
1. Switch on the device
2. Hold down the PS1 button until all the LEDs flash quickly.
3. Release the button
4. The device restarts and the LEDs
On Z-KEY-P: PWR and SD/COM
On Z-KEY-2ETH-P: PWR and COM
On R-KEY-LT-P: PWR and COM
flash slowly to indicate webserver mode
To force Profinet mode:
1. Switch on the device
2. Hold down the PS1 button until all the LEDs flash quickly.
3. Release the button
4. The device restarts and the LEDs
On Z-KEY-P: PWR and SD/COM
On Z-KEY-2ETH-P: PWR and COM
On R-KEY-LT-P: PWR and COM
stop flashing slowly to indicate the Profinet mode.

Status
It is the section that displays the values of the configured tags in real time.
Setup
It is the section that allows the device basic configuration.
Setup Tag
It is the section that allows adding/modifying the tags (that is the variables) of the Modbus devices connected
to the gateway.
Firmware Update
It is the section that allows updating the firmware and database.
Database Update
It is the section that allows updating the firmware and database.
Traffic Monitor
It allows to analyse the ModBUS frames of the serials.
