I/O Configuration for Intrinsically Safe Discrete Modules
Overview
This section provides information on the I/O configuration of the intrinsically safe
discrete modules, 140DII33000 and 140DIO33000.
Intrinsically Safe Discrete Input Module
The following is the intrinsically safe discrete input module:
z 140DII33000 (DC, intrinsic safe)
I/O Map Register Assignment
This 8-point input module can be configured as either 8 contiguous discrete input
(1x) references or as one 3x register. The following figure shows an I/O map
register.
I/O Map Status Byte
There is no I/O map status byte associated with this module.
Modsoft Module Zoom Selections
Push <Enter> to display and select the input type. The following figure shows the
input type display.
CAUTION
I/O Mapping Rules
When I/O mapping input modules using discrete (1x) references in remote drops,
users should not split discrete words between drops. The lowest discrete reference
for a drop should start on a word boundary.
Failure to follow these instructions can result in injury or equipment damage.
