Here is a brief description of the three fields in the Discrete Outputs panel:
•
Outputs –– The two selections in this field are Enabled and Disabled .
“ Enabled ” allows the discrete outputs to become active during online
operations, and to reflect the results of inspections. “ Disabled ” causes all
outputs (except the designated Strobe outputs) to remain inactive during
online operations.
•
Forces –– The two selections in this field are Enabled and Disabled .
“ Enabled ” allows all discrete outputs that are configured with a “ Force ”
selection of “ On ” or “ Off ” to reflect the Force selection during online
operations. “ Disabled ” prevents the Force selections from operating.
Note that if “ Disabled ” is selected in the Outputs field, the selection in
the Forces field has no effect.
•
PLC Test –– The two status conditions displayed in this field are On and
Off . When the “ On ” status is displayed, all discrete outputs are disabled
(except the designated Strobe outputs) regardless of the selection in the
Outputs field. When the “ Off ” status is displayed, the outputs are subject
to the selections in the Outputs and Forces fields.
The “ On ” status will appear only when an Allen–Bradley programmable
logic controller (PLC
) is connected to the
Remote I/O port and the
PLC is set to the “test” or “program” mode.
NOTE: The “ Off ” status can be restored only when the PLC reports that
its has returned to the “run” mode. If communications with the PLC are
disrupted after the PLC has set the “
On ” status, the “ Off ” status can be
restored only by cycling the power to the CVIM2 module.
