Digital I/O Option Card
Configuration of the Digital I/O option
card is done mainly as a mapping
function that is explained in Section 6.
However, you can open the screen to the
right from the Configuration menu.
Step 1. From the Configuration menu;
select Options to open the
options menu; then select
Digital I/O Card to open the
Digital Input/Output page.
Step 2. Read-only I/O Board Inputs
and Main Board Inputs display
at the top of the page. If the
input is sending a voltage
signal, the status is 1. If there is no
voltage signal for the input, the status is 0.
Step 3. Each of the Outputs refers to a relay associated with a process.
The pull-down options
allow you to place a relay in
service or take it out of
service for setup testing.
However, if a relay has been
mapped, the mapped
activity will override a
manual Start or Stop activity
set on this page.
NOTE Warning: Turning relays ON or OFF during an active process can disrupt the process
and result in serious problems.
Avertissement: Mettre les relais en état « Allumé » ou en état « Eteint » durant le
processus de fonctionnement peut perturber le processus et provoquer des
problèmes graves.
Step 4. To toggle the output ON, click 1, or to toggle the output Off click 0.
Step 5. You need to map controls to the Digital Card Outputs. For example you might
need to map a Setpoint (Setpoint 1Output HSI2) to Digital Card Output 1 (HO0.0)
you need to create this map: HO0.0 = HSI2. Refer to Chapter 6 - Mapping for
more instructions.
