SETTING THE DIP-SWITCHES
WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.
SW1 DIP-SWITCH:
Through DIP-SWITCH-SW1 it is possible to set the IP configuration of the
device:
| DESCRIPTION | DIP 1 | DIP 2 | DIP 3 | DIP 4 |

FACTORY IP ADDRESS
The default module IP address is static: 192.168.90.101
WEB SERVER
To access the maintenance Web Server with 192.168.90.101 factory IP address
enter:
http://192.168.90.101
Default user: admin, Default password: admin
N.B.: For the Z-KEY-MBUS-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.
WEB SERVER AND PROFINET MODE (Z-KEY-MBUS-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 Setup 2 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 “PS1” button pressed until all the LEDs go off
- Release the button
- The device restarts and the PWR and COM LEDs flash slowly to indicate webserver mode
To force Profinet mode:
- Keep the “PS1” button pressed until all the LEDs go off
- Release the button
- The device restarts and the PWR and COM LEDs stop flashing slowly to indicate Profinet mode
IDC10 CONNECTOR
The illustration shows the meanings of the various IDC10 connector pins if
signals are to be sent via them directly.
INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life, adequate ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots. Avoid mounting modules over heat-generating equipment. Installation in the bottom part of the electrical panel is recommended.
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.
ELECTRICAL CONNECTIONS
CAUTION
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…).

Use only copper or copper-coated aluminum or AL-CU or CU-AL conductors
CONNECTION STANDARDS
Type of installation| Maximum speed| Connection maximum
distance| Connection total length| Type of cable
---|---|---|---|---
Small in house| 38400| < 350 m| < 1000 m| 0.5 mm2, R < 30 Ω
Large in house| 9600| < 350 m| < 3000 m| 0.5 mm2, R < 30 Ω
Small wide area| 2400| < 1000 m| < 3000 m| 1.5 mm2, R < 90 Ω
Meter BUS is a non-polarized bus. For the connection it is possible to use a
two-wire shielded telephone cable or an unshielded duplex cable following the
indications in the table.
If a shielded cable is used, this must be connected to earth only from the
side of the Z-KEY-MBUS instrument.
