1.1 For Using Logging and Trace Functions
1.1.1 Precautions on Using This Function
As an SD memory card is used for the logging function, there are risks of loss of data or data
damage depending on usage conditions. Consider possible risks, design a system and make
an evaluation of the system before using the function.
■Precautions when powering off the PLC
If the PLC is powered off during logging or accessing an SD memory card, the following
problems may occur.
● Data accumulated in the buffer memory are lost.
● Files may be damaged.
● The SD memory card may be damaged.
Take necessary measures such as the use of an uninterruptible power system (UPS) as
necessary.
■Logging speed and writing speed into an SD memory card
When the speed accumulating data is faster than the writing speed into an SD memory card,
data cannot be saved. Make an evaluation thoroughly before use.
1.1.2 Models Supporting the Logging/Trace Function
The following FP7 CPU Units support the logging/trace function.
Function Supported
Logging All FP7 CPU Units other than the low-cost type (AFP7CPS2R)
Trace All FP7 CPU Units
1.1.3 Selection of SD Memory Cards
■Usable SD memory cards
We recommend SLC SD memory cards and SLC SDHC memory cards.
For details on compatible SD memory cards and SDHC memory cards, visit https://
www3.panasonic.biz/ac/e/fasys/information/sd-card/index.jsp.

1.1 For Using Logging and Trace Functions
1-2 WUME-FP7CPULOG-04

■Cautions on handling an SD memory card
The data saved in the SD memory card may be lost in the following cases. We assume no
responsibility whatsoever for the loss of saved data.
● When the user or a third party has misused the SD memory card.
● When the SD memory card was affected by any static electricity or electrical noise.
● • The SD memory card was taken out, or the PLC body was powered off, while the card was
being accessed (e.g. saving data into the card, deleting data from the card).
■Formatting an SD memory card
In principle, SD memory cards have been formatted by the time of purchase, and no formatting
by the user is required. If formatting becomes necessary, download formatting software for SD
memory cards from the SD Association website.
● A file system formatted by PC's standard formatting software does not satisfy the SD
memory card specifications. Please use the dedicated formatting software.
It is recommended to save important data in another media for backup.
Never remove the card or power off the PLC body while the SD LED on the CPU unit is
flashing (data is being read from or written into the card). Data may be damaged.
● Do not use an SD memory card the memory capacity of which is more than the usable
capacity. Data in the card may be damaged.
1.1 For Using Logging and Trace Functions
WUME-FP7CPULOG-04 1-3

1.2 Overview of Functions
1.2.1 Overview of Logging Function
■Overview
● The logging function is used to record arbitrary contacts and data information together with
time stamp information at any time, and save them in an SD memory card inserted in the
CPU unit.
● Log data is saved as csv format files.
● Use the Logging/Trace Settings menu of the tool software FPWIN GR7 to set the
conditions.
● The settings are downloaded to the PLC as a part of project data, and stored in the ROM1.
The setting data can be saved in SD memory cards and used.
● The logging operation is executed by any of these operations: (1) tool software FPWINGR7,
(2) dedicated instructions or (3) Autostart via setting.
● To perform data logging at high speed, the buffer memory in the CPU unit is used.

1.2.2 Overview of Trace Function
■Overview
● The trace function is used to record arbitrary contacts and data information together with
time stamp information in the buffer memory in the CPU unit at any time.
● Logging data can be uploaded from the buffer memory to the tool software after the trace
operation, and can be displayed as a time chart. Traced data can be saved in SD memory
cards as csv format files.
● When the trace stop condition is set to bit device, the operation can be stopped after logging
data of the specified number of samplings after the stop condition has been met.
● Use the Logging/Trace Settings menu of the tool software FPWIN GR7 to set the
conditions.
● The settings are downloaded to the PLC as a part of project data, and stored in the ROM1.
The setting data can be saved in SD memory cards and used.
● The logging operation is executed by any of these operations: (1) tool software FPWINGR7,
(2) dedicated instructions or (3) Autostart via setting.
