  • Page 6: Safety Notes

    Do not use any contact spray. The spray may impair the functioning of the contact area. The WAGO-I/O-SYSTEM 750 and its components are an open system. It must only be assembled in housings, cabinets or in electrical operation rooms. Access must only be given via a key or tool to authorized qualified personnel.

    Connect the supplies for the controller and for the power jumper contacts to the DC 24 V power supply unit 787-602 (see Fig.1). In this example it would be sufficient to bridge “24V“ and “+“ or “0V“ and “- “. Fig.1: 10/100 MBit ETHERNET fieldbus controller 750-841 WAGO-I/O-SYSTEM 750 ETHERNET StarterKit 2...

  • Page 8: Ethernet Network Start-Up

    Connect your PC with the configuration and programming interface of the node. Install the “WAGO Ethernet Settings“ program, which you can find either on the “Tools & Docs“ CD-ROM or on the WAGO Web pages under Service Downloads Software. After starting, the program identifies the current settings of the node.

In this case, the allocation is done via the Ethernet interface of the device so that no separate serial cable is required.

This will open the I/O configuration window with the I/O module catalog. Fig. 13: WAGO-I/O-PRO CAA, with I/O configuration dialog .In the application example shown in section 2.1, a single 750-400 digital in- put module has been connected to the 750-841 controller, followed by a 750- 501 digital output module.

Fig. 14: WAGO-I/O-PRO CAA, PLC configuration with 750-400 and -501 In this example, we first used the “PLC“ value. The I/O configuration window now shows the address of each channel, and thus each individual bit on the module.
