9.15 Check and change the Node ID of a module
Introduction
Node ID is a unit number designation that is used by the instrument to distinguish be-
tween several units of the same type. All standard valves and available optional modules
are pre-configured to the default function. However, the function of a valve or module
can be changed by changing the Node ID. Also, in a troubleshooting situation it may be
useful to check a valve's or module's Node ID.
The function of a valve or module is defined by its Node ID, not by its physical
position.
Note:
Node ID for standard modules
The following table lists the Node ID for the standard modules.
