20.7 States of the Data Logging Function
The data logging function has the data logging state. The data logging state can be checked by CPU Module Logging
Configuration Tool. ( CPU Module Logging Configuration Tool Version 1 Operating Manual (MELSEC iQ-R Series))
Data logging states
The following table lists all the possible data logging states.
*1 CPU Module Logging Configuration Tool displays "Saving the logging data" as the data logging state until saving of collected data
completes. After the completion, the state changes to each of three states.
*2 The execution of another function includes:
 Execution of data logging with the same trigger conditions (trigger conditions = the specified conditions)
 Auto logging
 Online change
Data logging status in redundant system
The following table describes each data logging status in the redundant system.
Data logging states Description
Stop
*1
Data logging settings are unregistered and data collection is inactive.
Stop (after collection) Transition from "Collection completed" to "Stop" has occurred due to the execution of another function
*2
.
Stop (after error) Transition from "Error" to "Stop" has occurred due to the execution of another function
*2
.
RUN waiting (no collection) Data collection has not yet begun because the operating status of the CPU module is not in the RUN state.
Start waiting (no collection) Data collection is inactive, waiting for the start command.
Pause
*1
Data logging is suspended and data collection has not yet been started. (The data logging settings remain intact.)
Condition waiting (no collection) Data logging settings are registered and waiting for the first collection timing.
Collecting Continuous logging is active and collecting data.
Trigger waiting (Collecting before trigger) Data logging settings are registered, data collection is being performed, and waiting until the trigger condition is
met.
Collecting after trigger Trigger logging is active and collecting data after the trigger condition is met.
Collection completed
*1
• Continuous logging: Data collection has finished upon reaching "Number of files to be saved" specified as part of
the "Stop" setting configured in "Operation when exceeds the number of files". (The data logging settings remain
intact.)
• Trigger logging: Trigger logging has finished collecting data as much as the specified number of records. (The
data logging settings remain intact.)
Error Data logging has failed due to the occurrence of an error.
Data logging states Description
Stop No data logging settings are registered and data collection is inactive.
Stop (after collection) Transition from "Collection completed" to "Stop" has occurred due to the execution of another function
*1
.
Stop (after error) Transition from "Error" to "Stop" has occurred due to the execution of another function
*1
.
RUN waiting (no collection) • Data collection has not yet begun because the operating status of the CPU module is not in the RUN state.
• After the operation mode of the redundant system was changed to the separate mode, the CPU module of the
standby system enters the wait state for the RUN-transition instruction.
Start waiting (no collection) Data collection is inactive, waiting for the start command.
Pause Data logging is suspended and data collection has not yet been started.
Condition waiting (no collection) Waiting for the first collection timing after the start operation
Collecting Continuous logging is active and collecting data.
Trigger waiting (Collecting before trigger) Trigger logging is active, data collection is being performed, and waiting until the trigger condition is met
Collecting after trigger Trigger logging is active and collecting data after the trigger condition is met.
Collection completed • Continuous logging: Data collection has finished upon reaching "Number of files to be saved" specified as part of
the "Stop" setting configured in "Operation when the number of files exceeds the set value".
• Trigger logging: Trigger logging has finished collecting data as much as the specified number of records.
Error Data logging has failed due to the occurrence of an error.
Standby system start waiting Data collection has not been performed, waiting for the start operation in the standby system.
Standby system pause Data logging is suspended in the standby system.
Standby system no collection Data logging is started in the standby system, but data collection is inactive.
