Digital Input Configuration

DI: Input Type

An XT-9100 can accept up to 16 digital inputs, which will be considered active when driven to a common digital ground. The first eight digital inputs are connected to XP1 and the next eight digital inputs to XP2.

Each digital input is defined and configured by the following parameters:

∙Tag name (optional, GX-9100 only)

∙Input type

∙Counter prescaler

Inputs may be defined as maintained or pulse type. With maintained type contacts the extension module status follows the status of the contact. With pulse type contacts the extension module sets and resets the status at each pulse of the input contact.
