How to modify the parameters of an AS-i V2 slave

At a Glance

The Parameters zone of the configuration screen enables the user to choose whether or not to activate the parameters of certain slaves.

The parameters displayed differ according to the slave in use, please refer to slave documentation for further details.

Example of parameters

On certain slaves, the following may be activated:

The internal watchdog, upon a communication stop with the (TSX SAY 1000) bus master.
The output fallback position pre-programmed in the slave.

This parameter activates the slaves' output fallback when changing to STOP or when the PLC is faulty.

The fallback position is pre-defined in the slave device. Possible modes are:

Fallback to 0: the outputs of AS-i slaves present on the bus are set to 0 status.
Maintain status: AS-i slave outputs remain in the state they were before STOP mode was engaged.
