DHCP Server is recommended.
The DCHP server automatically assigns the appropriate network settings to your nodes in the local network. A
manual network configuration is therefore not necessary. In a local network, the Internet router is usually the
DHCP server. If the IP addresses in the local network are to be assigned dynamically, DHCP must be activated in
the Internet router (see the Internet router manual). In order to receive the same IP address by the internet router
after a restart, set the MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the free address pool of
the network segment to all network participants to be integrated during commissioning.

Use of Ethernet devices
Please observe the following information if you use Ethernet devices in your system:
• Do not connect the control components and control networks with an open network such as the Internet.
Always install control components and control networks behind a firewall.
• Restrict physical and electronic access to all automation components to a group of authorized persons.
• Be sure to change any automatically generated passwords before initial commissioning. This will reduce the
risk of unauthorized persons gaining access to your system.
• Regularly change your passwords. This will reduce the risk of unauthorized persons gaining access to your
system.
• If remote access to control components and control networks is required, use a virtual private network (VPN)
whenever possible.
• Carry out regular threat assessments. This will allow you to make sure that the measures in place match your
protection needs.
• When it comes to the safety-oriented design of your system, use defense in depth mechanisms to restrict
access to and control of individual products and networks.

4 Product Overview
4.1 WAGO-I/O-SYSTEM 750
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus-independent input/output system (I/O system). The configuration
consists of a fieldbus coupler, supply module, and the assembled I/O modules for any signal type. These I/O modules
together make up the fieldbus node. The bus end terminal completes the fieldbus node and is required for correct
operation.

H Bus end terminal 750-600
4.2 Fieldbus coupler
The fieldbus coupler 750‐352 or 750-362 combines the modular WAGO‐I/O‐SYSTEM with Ethernet.
The fieldbus coupler detects which I/O modules are plugged in and uses them to generate a local process image,
which corresponds to the Modbus profile in Data Manager M. The two RJ45 ports, which both function as 2-channel
network switches, make it easy to wire the fieldbus in a line topology. This eliminates the need for additional
components such as network switches or Ethernet hubs.

4 Product Overview SMA Solar Technology AG
Installation ManualEDMM-WAGO-IO-IA-en-1112
The interfaces can be connected to any Ethernet system. The data transfer rate and pin assignment are determined
automatically. The IP address is assigned via DHCP by default. Alternatively, the address selection can be used to
assign the last byte of the IP address as well as the use of a fixed IP address. The fieldbus coupler is suitable for
fieldbus communication with Modbus TCP.

4.4 I/O modules
Different sensors and actuators are connected to the WAGO-I/O-SYSTEM 750 via the I/O modules. Single-, multiple-,
or fine-wire conductors can be connected via the CAGE CLAMP® connections. The terminal bus is responsible for
communication between the fieldbus coupler/controller and the individual I/O modules. The terminal bus is comprised
of 6 self-cleaning gold-spring contacts. Field supply voltage is used for the voltage supply.
The I/O modules receive the 24 V supply potential and the 0 V potential for the field level via the power contacts of
the respective upstream I/O module or the supply module and also conduct this potential to the downstream I/O
module.
