Write Setting Parameters
(Download)
Use this function to download the setting parameters from the DeviceNet
Communications Unit to the Temperature Controllers.
Note
1.
While downloading, refresh processing of I/O data will stop, and the data
immediately before being copied will be held in the IN Area of the De-
viceNet Communications Unit. Explicit message communications will stop,
so a timeout error may occur.
2.
After downloading has been completed, a software reset will be imple-
mented for the Temperature Controller. Even if the Temperature Controller
is in RUN mode, the Controller will stop after downloading when the follow-
ing conditions are met.
• The RUN/STOP Bit in the OUT Area for the channel is ON.
• The Output Enable Bit in the OUT Area for the channel is OFF.
■
Execution Condition
• Data for the same connection configuration (model, unit number) has
been uploaded to the DeviceNet Communications Unit.
• There can be no communications error (TS indicator is not flashing red).
■

data will start downloading and the TS indicator will flash green.
■
Execution Results
• When the download completes normally, the TS indicator status returns to
be lit green.

the TS indicator will flash red for 10 s.
