SD Memory Card Operations

In the OPC UA Server, the SD Memory Card mounted in the CPU Unit is used for the Execution Log
function.
The Execution Log files are stored in the SD memory card.
This section describes how to save the Execution Log files in the SD Memory Card and precautions for
replacing the SD Memory Card.
Refer to the NJ/NX-series CPU Unit Software User's Manual (W501) for details on the SD Memory
Card functions.
7-4-1 Conditions for Saving Execution Log Files to the SD Memory
Card
Execution Log files are saved to the SD Memory Card under the following condition.
Operation to use the function
Set Execution Log to Record in OPC UA
Server Settings of the Sysmac Studio.
*1 If the power supply to the CPU Unit is turned on while no SD Memory Card is mounted in the CPU Unit, an
Execution Log Save Failed event (event code: 15000000 hex) is registered in the event log when an Execu-
tion Log is saved. Recording of the Execution Logs starts when an SD Memory Card is inserted into the CPU
Unit.
Even while the Server operating status of the OPC UA Server is preparing or running, recording of the Execu-
tion Log files will just start at the point of time when an SD Memory Card is inserted.
7-4-2

Directories Used for the OPC UA Server

The OPC UA Server uses the directories under packages/OPCUA_Server in the SD Memory Card as
shown in the following table.
Directory

/packages/OPCUA_Server/System
Precautions for Correct Use
Do not delete the following files in the SD Memory Card.
• OPCUA_ExecutionLog.log (latest log file)
• OPCUA_ExecutionLog.fjc (log control file)
If they are deleted, the log files will not be saved correctly; for example, the Execution Log data
will be lost.
