Allocating PT Memory to the Host (Master)

After a short time, turn the scan list clear bit OFF again. We recommend
turning the bit OFF after verifying the results of the operation in the master
status area.
9. Use a PC Programming Device to turn bit 00 of the software switches (the
scan list enable bit) from OFF to ON.
After a short time, turn the scan list enable bit OFF again. We recommend
turning the bit OFF after verifying the results of the operation in the master
status area.
If the remote I/O allocation was registered properly and the Master is operat-
ing in scan list enabled mode, the dot display on the Master Unit’s 7-seg-
ment LED will be OFF and remote I/O communications will start with the reg-
istered allocation.
Use a PC Programming Device to check whether remote I/O communica-
tions are operating as expected.
When the remote I/O allocation has been performed properly, remote I/O
communications will start automatically the next time that the Master starts.
Free (User–set) Allocation
Use the following procedure to register the remote I/O allocation area.
This example provides a summary of the relevant Configurator operations. Re-
fer to the DeviceNet (CompoBus/D) Configurator Operation Manual (W328) for
more details.
Reference This example explains the allocation when there is only one Master. Refer to the
DeviceNet (CompoBus/D) Operation Manual (W267) for details on allocation
with more than one Master.

1. Turn ON the Master (PC) after making any required Master Unit hardware
settings. Refer to the DeviceNet (CompoBus/D) Operation Manual (W267)
for details on Master Unit hardware settings.
2. Connect a Programming Device to the PC, turn ON the Master (PC), and
create the I/O table.
3. Turn OFF the Master (PC).
4. Connect the Configurator to the DeviceNet network.
5. Turn ON all of the Slaves.
Make the required settings in the DeviceNet memory switch screen of the
PT connected to the DeviceNet Interface Unit and reset the PT. Always set
the input area size and output area size first.
6. Put the Configurator in online mode and read the network configuration.
7. Create the Mater parameters. The Master parameters contain the input and
output area settings and Slave I/O allocation. Always save the Master pa-
rameters in a file.
8. Turn OFF all of the Slaves.
9. Turn ON the Master (PC).
10. Read the network configuration with the Configurator.
11. Switch to the Master Unit’s device parameters editing page in the Configura-
tor, read the Master parameter file created in step 7., and write those Master
parameters to the Master Unit.
12. Turn ON all of the Slaves.
13. Start remote I/O communications with the Configurator.
Use a PC Programming Device to check whether remote I/O communica-
tions are operating as expected.
When the remote I/O allocation has been performed properly, remote I/O
communications will start automatically the next time that the Master starts.
