6. Configuring the Gateway

6.11.2.1. Managing Degraded Modes

Due to the number of hardware elements and software tools used, the following table shows a summary of the various degraded modes in a DeviceNet application. In this case, this application includes an LUFP9 gateway, but we will not be including either the master PLC or its scanner:

(1)The “Offline options for fieldbus” and “Offline options for sub-network” are described in the next chapter.

(2)The behaviour desired with regard to the outputs should be directly configured on each of the Modbus slaves. In the case of drives marketed by Schneider Electric, for instance, resetting the outputs is configured by setting the NTO bit to 0 (communication control), and they are held by setting NTO to 1 (suppression of communication control).

You can also read the user manuals for your master and your DeviceNet scanner to obtain further details about how to process degraded modes.
