10.3 Data storage
The data storage function stores the IO-Link device parameters data in the IO-Link master.
Refer to
10.2.2. (2) SMC parameters (P.
).
(1) Storage of the changed parameter data
The JXC controller parameters specified can be stored in the data storage server of the IO-Link
master.
In order to store the parameter, write "ParamDownloadStore (command code: 0x05)" to the system
command of Index:0x0002,SubIndex:0x00. The parameters will be sent by the JXC controller.
When a system command is sent, the JXC controller will send the changed parameter data to the
IO-Link master. When the IO-Link receives the data, it stores the data in the data storage server of the
IO-Link master.
When a block parameter function of the IO-Link master tool is enabled and all the parameters are
set in a batch, "ParamDownloadStore" is automatically sent to the system command as a part of the
block parameter sequence.
Caution
When step data or actuator parameters are changed using an ACTController or teaching box,
turn the IO-Link power supply L+/L- to the JXC controller off and on again before storing the
parameter to the IO-Link master data storage server.
If the power supply L+/L- is not turned off and on again, the changed parameters are not reflected to
the SMC parameters in the IO-Link communication parameters of the JXC controller.
(2) Restoration of parameters changed during a JXC controller replacement
When a JXC controller is replaced with one of the same model number, the specified parameters
stored in the IO-Link master are automatically downloaded to the new JXC controller. The stored
parameters overwrites the default parameters of the JXC controller so that the existing controller
parameters are reflected in the replacement controller .
Caution
Replace the JXC controller after confirming that the model number of the JXC controller to
replace is the same as the JXC controller to be replaced.
Moreover, if the JXC controller is replaced with JXCL1
-BC (The blank controller), replace the
JXC controller after writing the parameters for the connected actuator by JXC-BCW.
In Data storage, after replacing, only a part of parameters is downloaded to the JXC controller. The
other parameters needed to drive the motor of the connected actuator are not downloaded.
10.4 Fail safe
Once IO-Link communication is established, if an IO-Link communication error occurs or the IO-Link
power supply is disconnected, the connected actuator is stopped based on the operation instructions
shown below.
Numerically instructed operation, Step No. instructed
operation, inching, return to origin
Jogging
Stop after moving a specified distance
Immediate stop
If an alarm relating to the motor control has not been generated, the actuator is able to operate when
IO-Link communication is recovered. The process data during communication recovery is as follows.
