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.

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 this instruction can result in injury or equipment damage.
