on the device parameters upload and download functions, refer to the
De-
viceNet Configurator Ver. 2

When replacing a Temperature Controller, the DeviceNet Communications
Unit copy mode can be used to easily reset the Temperature Controller on-
site without requiring the Configurator. For details, refer to
Reading/Writing
Temperature Controller Settings Using Copy Mode
below.
Reading/Writing
Temperature
Controller Settings
Using Copy Mode
The DeviceNet Communications Unit has a copy function that can read or
write the setting parameters of all the Temperature Controllers connected to
the Unit in a batch (the read setting parameters are recorded in the DeviceNet
Communications Unit).
When a Temperature Controller has been replaced, the copy function allows
the Temperature Controller to be easily reset onsite without using a Configu-
rator.
Note
1.
The parameters of the G3ZA and G3PW are not backed up. If backup is
required, use the CX-Thermo to back up the parameters.
2.
Once a system using a DeviceNet Communications Unit is operating prop-
erly, it is recommended to read the Temperature Controller parameters us-
ing the copy function at the same time as the device parameters are saved
using the Configurator.
3.
The copy function can be used with explicit messages also. For details, re-
fer to page 123.
Read Setting Parameters
(Upload)
Use this function to upload the setting parameters from the Temperature Con-
trollers to the DeviceNet Communications Unit.
■
Execution Condition
There can be no communications error (TS indicator is not flashing red).

Procedure
1,2,3...
1.
Turn OFF pin 3 (UP/DN) of the DIP switch of the DeviceNet Communica-
tions Unit.
2.
Toggle pin 6 of the of the DIP switch of the DeviceNet Communications
Unit from OFF to ON (leave ON for 1 to 5 seconds) and then turn OFF
again (while pin 6 is ON, the TS indicator will be lit green). The data will
start uploading and the TS indicator will flash green. (Approx. 10 s is re-
quired for each Temperature Controller.)
