(2) Saving parameters
The information of a slave station performing data link through the automatic CC-Link startup is stored in the flash
ROM inside a bridge module using the slave station information saving function.
If the startup mode switch of a bridge module is set to PRM with the slave station information saved, the
parameters are set based on the saved data. Then CC-Link is started, and data link is performed.
(a) Operating procedure
The following is a procedure for saving slave station information.
1.
Start CC-Link using the automatic CC-Link startup function. ( Page 56, Section 7.2.1 (1) (a))
2.
Hold the startup mode switch in the SET position until the CC-Link RUN LED of the bridge module
turns off (about five seconds).
Slave station information is saved in the flash ROM inside the bridge module.
3.
The bridge module is reset and data link is started by executing the automatic CC-Link startup
again.
4.
Set the startup mode switch of the bridge module to PRM.
5.
The bridge module is reset and the parameters are set based on the saved slave station
information.
6.
The RUN LED and L RUN LED on the CC-Link side turn on.
7.
CC-Link is started.
If the startup mode switch of the bridge module is set to PRM when the power supply of the module is
turned off then on, the parameters are set based on the saved slave station information and CC-Link is
started.
● When the slave station information saving function is executed, the remote station having the largest station number
among connected stations is recognized as the last station. The unconnected stations having a smaller station number
than the last station are set as reserved stations in the parameter when the slave station information is saved.
