Startup Procedure
Section 2-2
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.
14
Start remote I/O communications.
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.
---
When using explicit message com-
munications
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.
104
15
Set the initial settings or monitor
the Temperature Controller.
With the Configurator online, execute Temperature Con-
troller operation commands or perform monitoring from
the Edit Device Parameters Window for the DeviceNet
Communications Unit.
93
16
Upload the Temperature Controller
parameters to the DeviceNet Com-
munications 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 3 of the DIP switch on the front
panel of the DeviceNet Communications Unit, turn ON
pin 6 (1 to 5 s), and then turn it OFF again.
