Emerson iPro IPG215D - Configuring Digital Inputs

30 • iPro I/O Module Installation and Operation Manual 026-1741 Rev 0
• Alarm- an alarm entry will be added to the E2E
advisory log at the priority specified by AL_Prio.
• Notice - a notice will be added to the E2E advisory
log. For detailed information on the E2E advisory
log, reference the E2E User Manual.
AL_Prio
This field is the alarm priority level for the analog input
alarm that is generated when the input is configured and in
error.
4.3 Configuring Digital
Inputs
The I/O Module Digital Inputs are configured from the 
I/O Module application in E2E. There are 11 digital inputs
available for the 4 DIN 208D model iPro and 20 digital
inputs for the 10 DIN 215D model. E2E reads the logical
value of each input with polarity applied.
To configure digital inputs:
1. Login to E2E with username: user, password:
pass.
2. Press
+ keys at the same time to navigate
to the Network Summary screen.
3. Highlight the I/O Module device and press
 (SETUP), press + at the same time
to bring up more list. Select option C DI Setup
by pressing C on E2E keyboard.
4. In the DI Setup, there are three (3) fields per
digital input: Name, DI0X, and Polarity.
Name
Enter a descriptive name for the digital input point. The
name will be displayed on the status screen.
DI0x
This is the logical value of the digital input and can be
associated to other E2E applications.
Polarity
This is the polarity for the digital input. The polarity
parameter determines what physical state of the input
results in a logical TRUE or ON for the input value.
4.3.1 Digital Input Default Value
The digital input values may be linked to other E2E
applications and logic. If there is a communications failure
between E2E and the I/O Module, the digital inputs will
retain the last logical value before the offline event
occurred instead of switching to NOTACT or logical 0.
When the communication is successful again, the E2E will
get the current value for the digital inputs and change the
current value if necessary.
