12.3.1 Setting the DCSĆNET Network Drop Number and
Depth While Offline
To set the DCSĆNET network drop number and drop depth, follow
these steps:
Step 1.
While offline, access the Rack Configurator for the
AutoMax PC3000 whose DCSĆNET network drop number
you want to change.
Step 2. Select the PC3000 Network Interface, located in slot 5.
Step 3. From the Configure menu, choose Modify.
Step 4. Type in values for these fields:
D Network
D Drop Number
D Drop Depth
Step 5. Click OK to accept your changes
Step 6. Generate a configuration.
NOTE: This procedure changes only the Configuration File. You must
use the Change Drop command while online to make the new values
take effect.
12.3.2 Setting the Physical Drop Number Using the
Change Drop Command While Online
Other AutoMax DCSĆNET network modules use thumbwheels to set
the physical drop number. However, for the AutoMax PC3000, you
set the physical drop number while connected online to the
AutoMax PC3000. This drop number and the value entered offline
using the Rack Configurator must match.
Since you must set the drop number online, you must choose and
implement an online connection method. See chapter 10 for more
information.
