2. Hardware Implementation of the LUFP9 Gateway
2.7. Configuring DeviceNet Communication Features
This configuration should be carried out when the gateway is powered off.
The block of selector switches allowing you to configure the DeviceNet communication functions is hidden
behind the gateway cover g (see illustration in chapter 2.2 Introduction to the LUFP9 Gateway, page 13). To
remove this cover, all you have to do is slide the end of a small screwdriver between the top of the cover and the
gateway box, then carefully remove it.
The power supply of the gateway must be turned off before opening the cover.
Once the cover has been removed, make sure that you touch neither the electrical circuits nor
the electronic components.
The block of selector switches is shown in the diagram below, each switch being shown in its factory set
position:

A selector switch is in the 0 state when it is in the OFF
position and in the 1 state when it is in the ON position.
Any change to the gateway’s communication
functions will not be effective until the next time
that the gateway is powered on.
2.7.1. Encoding DeviceNet Speed
The gateway’s communication speed on the DeviceNet network must be identical to that of the DeviceNet
master.
The factory setting is 500 kbits/s.
This speed value depends on the position of selector switches 1 and 2.
