6. A list of all protocols supported by the controller is displayed. The BootP
protocol is activated by default. To disable the protocol, click on the check
box after BootP to remove the check mark.
7. You can disable other protocols you do not need in a similar way, or enable
protocols you wish to use. It is possible to enable several protocols at the
same time, since each protocol uses a different port.
8. To store the protocol selection, click the SUBMIT button and then perform
a hardware reset. To do this, either switch off the power supply of the
controller or press down the operating mode switch.
9. The protocol settings are now stored EEPROM and the controller is ready to
operate.
3.1.7 Programming the PFC with WAGO-I/O-PRO CAA
The WAGO 750-841 Programmable Fieldbus Controller (PFC) combines the
functionality of an ETHERNET fieldbus coupler with the functionality of a
Programmable Logic Controller (PLC). When the PFC is used as a PLC, all or
some of its I/O modules can be control locally with the use of WAGO-I/O-
PRO CAA. WAGO-I/O-PRO CAA is an IEC 61131-3 programming tool that
is used to program and configure the 750-841 PFC. I/O modules which are not
controlled locally (i.e., not controlled as a PLC), can be controlled remotely
through the 10/100 Mbps ETHERNET Fieldbus port.
