5.6 DISCRETE INPUT MODULES (DI0-17)
The Discrete Input Modules (DI0-17) generate logic levels based on the applied voltages or contact condition on the associated termi-
nals. Inputs DI2-17 are active only when the appropriate hardware options are installed. The 18 Discrete Input Modules are provided in
Table 5-6. Each one can be configured separately (total combined DIs and DOs for controller cannot exceed 18).

Title Definition
Discrete Input This is an indication of the
applied signal level after INV
conditioning (see below).
Input Invert This parameter specifies the
signaling protocol to use for the
DI value (see above):
0 - 1-ON
1 - 0-ON
Input: Open, 4-24VDC (OFF)
INV 0, 1-ON DI=0
INV 1, 0-ON DI=1
Input: Closed, <1VDC (ON)
INV 0, 1-ON DI=1
INV 1, 0-ON DI=0
Tag Name It is an assignable 10 character
name for the contact control
input.
