9.7 Access via network
Accessing the device via a network requires that it is connected to an ex-
isting Ethernet or RS485 network.
Further information about connection to an existing network is specified
in sections 7.11 „Connecting Ethernet“ on page 26, 7.12 „RS485 inter-
face“ on page 26 and 8.5 „Network settings“ on page 35.
i
If connection problems are experienced during access via net-
work, check the configuration of your security software.
Modbus
You can access certain data on the device via the Modubus protocol using
both Ethernet and the RS485. You need the Modbus protocol e.g. For the
connection with a control panel or a PLC. Modbus TCP/IP is supported for
Ethernet and Modbus RTU is supported for the RS485 interface.
The Modbus addresses of your device are stated in section 13 „Modbus
addresses“ on page 51.
Web browser (only Ethernet)
You can access the device data using all network devices which are fitted
with a web browser. You will require the IP address, subnetmask and pos-
sibly the MAC address of the device.
The network settings of your device are listed under Main menu > System
> Service > Network.
Open the web browser of your end device and enter the IP address of the
device in the address row. The page of the device will open and provide a
range of information.
TFTP protocol (only Ethernet)
You can access the device memory via a TFTP client software as long as
TFTP is activated in the network settings. You need the device IP address
for access.
