Page 24 2.7.2 System Supply 2.7.2.1 Connection The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply (-15% or +20 %). The power supply is provided via the coupler / controller and, if necessary, in addition via the internal system supply modules (750-613).
Page 25 The WAGO-I/O-SYSTEM 750 • 21 Power Supply Attention Resetting the system by switching on and off the system supply, must take place simultaneously for all supply modules (coupler / controller and 750-613). 2.7.2.2 Alignment Recommendation A stable network supply cannot be taken for granted always and everywhere.

Page 27 The WAGO-I/O-SYSTEM 750 • 23 Power Supply 2.7.3 Field Supply 2.7.3.1 Connection Sensors and actuators can be directly connected to the relevant channel of the bus module in 1-/4 conductor connection technology. The bus module supplies power to the sensors and actuators. The input and output drivers of some bus modules require the field side supply voltage.
Page 28 24 • The WAGO-I/O-SYSTEM 750 Power Supply Attention Some bus 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 a field supply is required for subsequent bus modules, then a power supply module must be used.
Page 29 The WAGO-I/O-SYSTEM 750 • 25 Power Supply Warning In the case of power supply modules with fuse holders, only fuses with a maximum dissipation of 1.6 W (IEC 127) must be used. For UL approved systems only use UL approved fuses.
Page 30 26 • The WAGO-I/O-SYSTEM 750 Power Supply Alternatively, fusing can be done externally. The fuse modules of the WAGO series 281 and 282 are suitable for this purpose.

Page 37: Shielding (Screening)
Note For better shield performance, the shield should have previously been placed over a large area. The WAGO shield connection system is suggested for such an application. This suggestion is especially applicable when the equipment can have even current or high impulse formed currents running through it (for example through atmospheric end loading).

Page 47 3.1.3.7 Hardware Address (MAC-ID) Each WAGO ETHERNET TCP/IP fieldbus controller is supplied from the factory with a unique and internationally unambiguous physical ETHERNET address, also referred to as MAC-ID (Media Access Control Identity). This is located on the rear of the controller and on a self-adhesive tear-off label on the controller’s side.
Page 48 The PLC cycle starts following a fault free start-up when the Operating Mode Switch is in the top position or by a start command from the WAGO-I/O-PRO CAA. The controller starts a PLC cycle by first reading the fieldbus data, I/O modules, and time data. Next, the PLC program in RAM is processed (scanned).

Page 129: Ethernet
The TCP/IP protocol stack offers a high degree of reliability for the transmission of information. In the ETHERNET TCP/IP fieldbus controller developed by WAGO, various application protocols have been implemented on the basis of the TCP/IP stack. These protocols allow the user to create applications (master applications) with standardized interfaces and transmit process data via an ETHERNET interface.
Page 130: Network Architecture – Principles And Regulations
It is possible to connect 64 I/O modules to an ETHERNET TCP/IP fieldbus coupler/controller. Note Use of the WAGO 750-628 Bus Extension Coupler Module and 750-627 Extension End Module enables support of up to 250 I/O modules on the 750-841 controller (with softwareversion ≥ SW 9).
Page 131 The “T” and “F” stand for ‘twisted pair’ and ‘fiber optic’, and simply indicate the cable type. 10Base-T, 100BaseTX Either the 10BaseT standard or 100BaseTX can be used for the WAGO ETHERNET fieldbus node. The network architecture is very easy and inexpensive to assemble with S- UTP cable as transmission medium or with cables of STP type.
Page 132 “data traffic cop” where the hub “polices” the data coming in and going out of the individual ports, so the data will only be transmitted to the required node. WAGO recommends using a switch rather then a hub, this will allow for a more deterministic architecture.
Page 133 Stations can be added or removed without network interruption. Moreover, in the event of a defective cable, only the network segment and the node connected to this segment is impaired. This considerably increases the fail-safe of the entire network. WAGO-I/O-SYSTEM 750 ETHERNET TCP/IP...
