File Batch Online Change - Mitsubishi Electric MELSEC iQ-R Series User Manual

File batch online change

This function writes programs and other data to the running CPU module in units of files.
For the operating procedure and the execution condition of the file batch online change, refer to the following.
 GX Works3 Operating Manual
Writing FB files and the global label setting file
The file batch online change of FB files and the global label setting file is available depending on the model and firmware
version of the CPU module. ( Page 747 Added and Enhanced Functions)
When executing the file batch online change of FB files and the global label setting file, configure the setting of the write target
file described below before system operation.
■Setting of the file to be written
1.
Check that SM388 (File batch online change operation setting status) is off.
2.
Set "AFBFH" to SD384 (System operation setting).
3.
Turn on SM384 (System operation setting request). SM384 automatically turns off. If writing has failed, SM385 (System
operation setting error) turns on and an error is stored in SD385 (System operation setting error cause).
4.
Check that SM385 is off, and turn off or reset the CPU module.
5.
SM388 turns on.
• This setting requires powering off the system or resetting the CPU module. For this reason, configure this
setting before system operation when executing the file batch online change of FB files and the global label
setting file.
• If the file batch online change is executed after this setting is configured (while SM388 is on), the scan time
may increase compared with the case when the file batch online change is executed before this setting is
configured (while SM388 is off).
• When using the Process CPU (redundant mode), configure this setting for both systems. Files can be
written only when the firmware version of the CPU modules in both systems supports writing of the FB files
and the global label setting file online.
■Procedure for clearing the setting (how to reset the write target file setting)
1.
Check that SM388 (File batch online change operation setting status) is on.
2.
Set "AFB0H" to SD384 (System operation setting).
3.
Turn on SM384 (System operation setting request). SM384 automatically turns off. If writing has failed, SM385 (System
operation setting error) turns on and an error is stored in SD385 (System operation setting error cause).
4.
Check that SM385 is off, and turn off or reset the CPU module.
5.
SM388 turns off.
