Contact input and output default assignment

Figure 393: Automation virtual output programming example

When a new settings file is created, the available contacts are assigned automatically to

the protection or automation functions according to the following convention:

First I/O module → protection

All subsequent I/O modules → automation

For example, if a D90

is configured with contact input/output cards in slots E, F, and G,

then the inputs and outputs associated with slot E are assigned to protection and the

inputs and outputs associated with slots F and G are assigned to automation.

These default assignments can be changed to match the requirements of the application.

This is done by right-clicking the setting filename and choosing the Manage Settings File >

I/O Assignments item. The following window displays.
