11-1 Outline of the Safety Data Logging
Function
The safety data logging is a function that records exposed variables and device variables used in the
safety program of the Safety CPU Unit in a chronological order. The function logs the specified varia-
bles in the volatile memory and saves the log data into the SD Memory Card before and after the trig-
ger condition is met. This function is available for a combination of an NX102 CPU Unit with unit ver-
sion 1.31 or later, or an NX-SL5
£££
Safety CPU Unit with unit version 1.3 or later, and Sysmac Stu-
dio version 1.24 or higher.
This section provides the specifications of the safety data logging.
Item Specifications
Number of logging settings 2 max.
Specify the respective settings including sampling interval,
trigger conditions, and logging target.
Number of records 3000 records per setting
Sampling interval Based on the task period of the NX102 CPU Unit, select one
of the four options specified by the Sysmac Studio for each
setting.
Trigger condition One variable can be specified as a trigger condition for each
setting.
BOOL variables: True or False
Non-BOOL variables: Select any of the following and specify
a constant:
= : Equal to the constant
≠ : Not equal to the constant
> : Greater than the constant
< : Less than the constant
≥ : Equal to or greater than the constant
≤ : Equal to or less than the constant
Logging target Up to 100 exposed variables and devices variables can be
specified for each setting.
Storage location of the safety data logging set-
tings file and log files The data is saved in the following folder of the SD Memory
Card that is mounted in the NX102 CPU Unit.
/SFLog/
The safety data logging function works as follows:
Logging standby
(waiting for start trigger)
Logging in-progress
(waiting for stop trigger)
Start Trigger
Stop Trigger
Status Operation
Logging standby (waiting for start trig-
ger) The safety data logging is not in progress. When the start trigger is
detected, it enters the "logging in-progress" state.
