2. Either PT memory switches or CompoBus/D setting switches can be se-

lected from the memory switch initialization menu. Select PT memory

switches to initialize settings other than those for the DeviceNet Interface

Unit.

3. When the CompoBus/D setting switches have been initialized, the Device-

Net Interface Unit will use 32 input words and 32 output words. The number

of words used by all of the Slaves (including the DeviceNet Interface Unit)

must not exceed the maximum number of words available in the Master. In

particular when the Master is a C200HS, a DeviceNet Interface Unit set to its

default settings will use all of the Master's available words.

If the number of words used by all of the Slaves exceeds the maximum num-

ber of words available in the Master, either reduce the number of Slaves or

reduce the number of words used by the DeviceNet Interface Unit by chang-

ing the settings of the CompoBus/D setting switches.

The memory switches for the DeviceNet Interface Unit that have been set in the

PT will all be returned to their factory-default settings by the CompoBus/D set-

ting switch initialization function.

Use the following operation in the system menu to initialize all of the memory

switch settings.
