To change this device property, enter the new object ID (device instance) and click the
‘Reassign’ button. Once you do this, you will need to return to the Who-Is page, clear
the cache, repeat the Send Who-Is and Refresh, and reselect your target device. You will
get an ‘unknown device’ error if you try to continue without reselecting the device since
the device ID has now changed.
6.4 Get Counts
Click ‘Get Counts’ to read the present object allocation configured in the device. The
counts will show up in the ‘Present’ column.
Working offline: Enter the object counts you will configure your device for at some point
in the future, then click ‘Get Counts’ to accept the changes for working offline.
6.5 Recalculate and Reconfigure Counts
Enter new object counts in the windows in the ‘Pending’ column. Click ‘Recalculate’ to
check to see if the count is valid. The recalculate will also be automatic any time you
move the mouse cursor from one window to another.
Begin by deciding how many commandable objects you want in the new configuration,
and enter that number as the Commandable Object Pool. The Basic Object Pool will be
recalculated to use the remaining resources. Commandable objects take more resources
than basic objects. With zero commandable objects, you can expect to see 315 basic
objects. The maximum number of commandable objects is 136, which leaves only 1
basic object. As you can see, there is more than a 2 to 1 ratio of resource requirements.
Once you have allocated some number of commandable objects in the pool, proceed to
enter object counts for each of the object types. A count of zero is permissible.
When you are ready to reconfigure the device with the new object allocation, click the
‘Reconfigure’ button.
NOTE: This action will completely erase all prior object map
configuration.
If you get services error code 46, or an error message about invalid configuration, you
are probably attempting to increase object counts toward the top of the list while
decreasing counts further down the list in a device with a relatively full count. Start by
reinitializing to all object counts set to zero except for Analog Inputs (which can be set to
some low number). Now that the device sees available objects in the pool, you can
proceed to allocate as desired.
Upon clicking Reconfigure, you can expect to see the following sequence:
