12 DEBUG FUNCTION
12.1 Memory Dump Function
Object data
This section describes the data to be collected by memory dump.
Data to be collected
Of the devices listed below, all devices that are within the range specified in the device settings are subject to the collection.
*1 Includes local devices as well. Note that to the memory dump file, the program names of collected local devices are output.
*2 All file registers that exist in the device/label memory are collected.
*3 The CPU module where the SFC function can be used supports this device. ( Page 1008 Added and Enhanced Functions)
Trigger condition
The following table lists the conditions to be used as a trigger. Set the trigger condition in the memory dump settings. ( GX
Works3 Operating Manual)
• On the occurrence of consecutive triggers, if the status of data save due to the previous occurrence of
trigger is "Save complete" of collected data, the next trigger is recognized as a trigger again. Note that
events other than the above are not recognized as a trigger condition.
• A trigger can be generated with trigger conditions combined. ( Page 224 Combining trigger conditions)
Device specification
Data are collected when the specified monitoring target data (bit data) turns on during the END processing. Even though the
value of the monitoring target data changes during a single scan, if the value during the END processing is same as that
during the last END processing, it is not recognized as a trigger. Completion bits (including error completion bits) used in
dedicated instructions cannot be used as a trigger.
For monitoring data, the following devices can be specified.
*1 A local device, index modified device, and indirectly specified device cannot be specified.
*2 Word devices allow bit specification only.
*3 In the engineering tool, specify TS as T (contact), STS as ST (contact), CS as C (contact), LTS as LT (contact), LSTS as LST (contact),
and LCS as LC (contact).
