Creation Trigger And Current Value Data Sampling - Mitsubishi Electric MELSEC iQ-R Series User Manual

Creation trigger and current value data sampling

When creating a report, the data is sampled with the data sampling method and sampling interval in which the current value
data and creation trigger are specified.
The data sampling methods are as follows. The sampling interval that can be specified differs depending on the data sampling
method.

The system configuration and the processing timing for each data sampling method is the same as those of the data logging
data sampling method. For more details, refer to the following:
Page 25 Sampling function
Creation trigger function
Creation trigger function starts report creation at the specified timing.
Creates a report file when the condition is satisfied to create the trigger.
The method for specifying the creation trigger is the same as that of the trigger conditions of the data logging function. For
more details, refer to the following:
Page 40 Trigger conditions
The following are the operations when creation triggers continuously occur.
• After a creation trigger occurs, if the next creation trigger occurs while the report file is being created, report
creation processing will not be performed (the creation trigger is ignored).
The number of times that the creation trigger is ignored can be checked by the creation trigger reoccurrence
count of 'report creation information 1 to 64' (Un\G4030 to 4989) in the buffer memory.
• Check whether the report is being created based on the 'report creation information' (Un\G4008 to 4011) in
the buffer memory. Also, the time required for reporting can be confirmed by the report creation time of the
'report creation information 1 to 64' (Un\G4030 to 4989) in the buffer memory.
When "At module startup" is selected for creation trigger, data logging files, which have been output before
turning OFF the power last time, can be output to the report by setting the data logging output. However, when
configuring this setting when there are no data logging files, an error occurs in the high speed data logger
module because no output target data exists at time of module startup.
