  • Page 27 The WAGO-I/O-SYSTEM 750 • 27 Power Supply Attention Some bus modules have no or very few power contacts (depends on the I/O function). Due to this, the passing on 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 83 Note Transmission via the fieldbus is supported by UCMM. Here, for the down- load of the PFC program, WAGO-I/O-PRO 32 counts as a subscriber. 1. Start the WAGO-I/O-PRO 32 software via ’Start/Programs’ or by double clicking on the WAGO-I/O-PRO-32 symbol on your desk top.
  • Page 84 6. Under "Online" click on the "Log-on" menu point to log into the Con- troller. (During online operation, the WAGO-I/O-PRO 32 server is active. The communication parameters cannot be polled.) 7. If there is not a program contained in the Controller, a window appears asking whether or not the program is to be loaded.

    3.2.7 Special DeviceNet Features of the Controller 3.2.7.1 Connection via the UCMM port In contrast to the fieldbus Coupler 750-306 as a Group 2 Only Server, the De- viceNet Controller supports the dynamic connection via the UCMM port (Un- connected Message Manager Port).

  • Page 86: Change Mac Id By Sw

    The MAC ID of the Controller can be changed via the network using the soft- ware (e.g. WAGO NETCON, RS NetWorx). For this purpose, the node ad- dress is stored in non-volatile memory. Should the address set at the DIP switch differ from the one set via the network using the software, the I/O LED changes its colour to orange.

  • Page 87: Configuration Software

    To allow a connection between the PLC and the fieldbus devices, the interface modules have to be configured with the individual station file. To this effect, the scope of the WAGO-I/O-SYSTEM 758 includes the WAGO NETCON software intended for design and configuration, start-up and diagnosis.
