I/O Assignment - Intergraph Smart Instrumentation - Help

The I/O assignment in Smart Instrumentation enables you to assign a channel to a specific instrument or a fieldbus segment.

I/O assignment for an instrument is performed in two stages:

1. Associating (coupling) an instrument with a control system tag.

2. Assigning the coupled pair to a channel.

I/O assignment for a segment is also performed in two stages:

1. Associating (coupling) each virtual tag with a control system tag.

2. Assigning the coupled pairs to an I/O channel.

   The software displays the available instruments according to the current I/O type.

   You can change the I/O type by setting the appropriate I/O assignment preference. For details, see Set I/O Assignment Instrument Tag Preferences.
