Note When fixed allocations are used, I/O is allocated
Enable the master's scan list and change the PLC to
RUN Mode.
Remote I/O communications will start, and the contents
of the IN and OUT Areas in the master and DeviceNet
Communications Unit will be synchronized.
Send explicit messages from the master.
Explicit messages can be used to perform control and
monitoring that cannot be achieved using the IN and
OUT Areas alone by sending explicit messages to the
DeviceNet Communications Unit.
With the Configurator online, execute Temperature Con-
troller operation commands or perform monitoring from
the Edit Device Parameters Window for the DeviceNet
Communications Unit.
When the system has started normally, upload (backup)
all the parameters to the DeviceNet Communications
Unit in case of Temperature Controller malfunction. This
will allow parameters to be easily reset onsite without
using a Configurator after replacing a Temperature Con-
troller.
Procedure: Turn OFF pin 2 of the DIP switch on the front
panel of the DeviceNet Communications Unit, turn ON
pin 1 (1 to 5 s), and then turn it OFF again.
Note When changing the baud rate of the master after starting the DeviceNet Com-
munications Unit, turn ON the communications power supply of the DeviceNet
Communications Unit again, and restart the Unit.
When setting the Configurator only, without a master, the baud rate of the
Configurator will be automatically detected.
Details
With the Configurator online, register the connec-
tion configuration of the Temperature Controllers in
the Edit Device Parameters Window for the
DeviceNet Communications Unit.
Use the following method to allocate I/O in the IN
and OUT Areas from the Parameters Window for
the DeviceNet Communications Unit.
a. Select the data to be allocated from the avail-
able allocation data.
b. With the Configurator online, download the data
to the DeviceNet Communications Unit.
To divide the IN Area used by the DeviceNet Com-
munications Unit into two blocks, select the
DeviceNet Communications Unit in the Edit Device
Parameters Window for the master, and click
Advanced to set the connections.
Dividing the IN Area into two blocks allows, for
example, RUN parameters such as set points (SP)
and process values (PV) to be allocated as DM
words in IN Area 1 and status information to be
allocated as CIO words in IN Area 2.
When using the Configurator to allocate user-set I/
O, allocate the IN and OUT Areas used by
DeviceNet in the master from the Edit Device
Parameters Window for the master. Click the Mas-
ter I/O Allocations Tab, specify the first word of the
addresses for IN Area 1, IN Area 2, and OUT Area
1, and download the parameters to the master.
