Configuration
The digital output channels support several operation modes and can be configured
from this page.

Channel:
Select the channel to be configured.

Tag Name:
Each channel can be given a tag name for identification.

Mode:
The operation mode of each channel can be configured here, or chan-
nels can be disabled to improve the performance of enabled channels. After a
channel has been configured, pressing
Submit
at the end of this page will apply
the changes.

Channel Mask:
Each channel can be disabled individually for reducing date
traffic during communication.

Refresh:
Refresh the configuration.

FSV (Fail-Safe Value):
The digital output channels can be set to generate a
predefined value when communication between a host controller and a WISE
digital module is broken. To do this, select the FSV check box for the module to
set the output channel to "logic high" when the WDT times out. If the FSV check
box is clear, the module will set the output channel to "logic low" if the WDT
times out. To set the module so that the
FSV
is triggered by the WDT, go to
Net-
work App
on the
Configuration
page to enable
Communication WDT Trigger
FSV
for all of the module's output channels, and then set the communication
WDT mode to "Communication WDT." The default host idle time is 720 s, and
this can be configured by entering a value in the
Host Idle (Timeout Sec)
box
(unit: s) in this page.

Pulse Output:
In pulse output mode, the selected digital output channel can
generate a continuous pulse train or finite pulses. The pulse width can be set by
entering a value in the
Low Signal Width
and
High Signal Width
boxes on the
Configuration
page (increment: 0.1 ms). The frequency and duty cycle of the
pulse output signal will be calculated automatically and displayed in the Output
frequency and Duty cycle boxes, respectively. Whether a continuous pulse train
or finite pulses will be generated is determined by clicking
Continuous
or
Fixed
total
, respectively. The number of pulses to be generated can be set by entering
