Therefore, you should always dimension the overcurrent protection according to the anticipated power usage. The system and field voltage of the WAGO-I/O-SYSTEMs 750 is supplied on the head stations and bus supply modules. For components that work with extra low voltage, only SELV/PELV voltage sources should be used.

Page 29: System Supply
System Supply 3.4.3.1 Connection The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply. The power supply is provided via the fieldbus coupler/controller and, if necessary, in addition via internal system supply modules 750-613. The power supply is reverse voltage protected.
Page 30: Dimensioning
System Description WAGO-I/O-SYSTEM 750 750-362 FC Modbus TCP; G4 System supply only with appropriate fuse protection! Without overcurrent protection, the electronics can be damaged. For 24V system supply input voltage an external fuse, rated max. 2 A, slow acting, min. 30 VDC shall be used.

WAGO-I/O-SYSTEM 750 System Description 750-362 FC Modbus TCP; G4 Re-establish the ground connection when the connection to the power jumper contacts is disrupted! Some I/O modules have no or very few power contacts (depending on the I/O function). Due to this, the passing through of the relevant potential is disrupted. If you require a field supply via power jumper contacts for subsequent I/O modules, then you have to use a power supply module.

System Description WAGO-I/O-SYSTEM 750 750-362 FC Modbus TCP; G4 Figure 8: Supply Module with Fuse Carrier (Example 750-610) Observe the maximum power dissipation and, if required, UL requirements! In the case of power supply modules with fuse holders, you must only use fuses with a maximum dissipation of 1.6 W (IEC 127).
Page 37: Figure 9: Removing The Fuse Carrier
WAGO-I/O-SYSTEM 750 System Description 750-362 FC Modbus TCP; G4 In order to insert or change a fuse, or to switch off the voltage in succeeding I/O modules, the fuse holder may be pulled out. In order to do this, use a screwdriver for example, to reach into one of the slits (one on both sides) and pull out the holder.
Page 38: Fusing External
The 24V input voltage for the field supply is provided with an external fuse with max. 10 A slow acting, min. 30 VDC, to be secured. For the external fusing, the fuse modules of the WAGO series 282, 2006, 281 and 2002 are suitable for this purpose.

750-362 FC Modbus TCP; G4 3.4.7 Power Supply Unit The WAGO-I/O-SYSTEM 750 requires a 24 VDC voltage (system supply). Recommendation A stable power supply cannot always be assumed everywhere. Therefore, you should use regulated power supplies to ensure the quality of the supply voltage.
Page 44: Grounding
The optimal setup is a metallic assembly plate with grounding connection which is electrically conductive linked to the carrier rail. The separate grounding of the carrier rail can be easily set up with the aid of the WAGO ground wire terminals. Table 11: WAGO Ground Wire Terminals Order No. Description 283-609 1-conductor ground (earth) terminal block make an automatic contact to the carrier rail;...
Page 45: Grounding Function
WAGO-I/O-SYSTEM 750 System Description 750-362 FC Modbus TCP; G4 3.5.2 Grounding Function The grounding function increases the resistance against electro-magnetic interferences. Some components in the I/O system have a carrier rail contact that dissipates electro-magnetic interferences to the carrier rail.
Page 46: Shielding
Higher shielding performance is achieved via low-impedance connection between shield and ground. For this purpose, connect the shield over a large surface area, e.g., WAGO shield connecting system. This is especially recommended for large-scale systems where equalizing current or high impulse- type currents caused by atmospheric discharge may occur.
Page 47: Shielded Signal Lines
I/O module can be achieved even in the presence of interference acting on the signal cable. On some WAGO devices you can directly clamp the shield. For all other devices use the WAGO shield connecting system.

Modbus TCP works according to the master/slave principle. The master controller can be a PC or a PLC. The fieldbus couplers of the WAGO-I/O-SYSTEM 750 are slave devices. The master requests communication. This request can be directed to certain nodes by addressing. The nodes receive the request and, depending on the request type, send a reply to the master.

Page 85: Assigning The Ip Address To The Fieldbus Node
IP address via the address selector switch. The basic IP address can be changed via the Web-based management or WAGO Ethernet settings (in the delivery state: 192.168.1.0). The subnet mask and default gateway values are taken from the static settings (as delivered: subnet mask = 255.255.255.0, default gateway = 0.0.0.0).
Page 86: Figure 39: Address Selection Switch, For Example The Value Setting "50
You can also change the static base address currently saved in the fieldbus coupler/controller as required. Proceed as described for example in the section “Assigning IP Address via “WAGO Ethernet Settings””.

13.2 Visualization and Control using SCADA Software This chapter is intended to give insight into how the WAGO ETHERNET fieldbus coupler/controller can be used for process visualization and control using standard user software. There is a wide range of process visualization programs, called SCADA Software, from various manufacturers.
Page 241 The operation of these programs is very specific. However, a few essential steps are described to illustrate the way an application can be developed using a WAGO ETHERNET fieldbus node and SCADA software in principle: Load the Modbus ETHERNET driver and select Modbus ETHERNET Enter the IP address for addressing the fieldbus node At this point, some programs allow the user to give the node an alias name, i.e.
