.
Open the
Output Module
drop-down list at the bottom left of the window (Figure 2-6) and
select
I/O Expansion Module
. The Discrete Output window will automatically reconfigure
to correspond to the I/O Expansion Module, as shown in Figure 2-6.

NOTE
When an existing .JOB file containing a WriteDiscrete function is loaded on an In-Sight sensor to which the
I/O Expansion Module has just been added, the Start Bit and Number of Bits parameters in WriteDiscrete
must be changed to reflect the new configuration of the I/O lines. For example, the physical output lines 0
and 1 become lines 8 and 9 (HSOUT 0 and HSOUT 1) when the I/O Expansion Module is enabled.

.
Select
OK
to save the new settings to the sensor’s flash RAM.
NOTE
An error message will appear if the I/O Expansion Module is not attached to the In-Sight sensor, and the
Discrete Output dialog will return to its default configuration. Verify that the I/O Expansion Module is
connected as described in Section 2.1, then repeat steps 1 – 12 as described above.
The sensor can also be configured to use the I/O Expansion Module by opening the Discrete
Input dialog and following step 11, as described above.
Once the I/O Expansion Module is selected in either the Discrete Input or Discrete Output
dialogs, it is automatically enabled for both inputs and outputs, and hardware handshaking may
be used in serial communications.
