Tracking data
The following table lists the tracking data that can be transferred from the control system to the standby system.
: Transfer possible, : Transfer not possible
*1 The data is automatically transferred regardless of parameter settings. ( Page 625 Auto tracking data)
*2 The data that is used in a program executed in both systems is not transferred. ( Page 647 Program Execution in Both Systems)
*3 Module labels are not transferred.
*4 Global labels/safety global labels with devices assigned are not transferred as global labels/safety global labels. They are transferred
according to the tracking settings/safety tracking settings of the assigned devices.
*5 Tracking transfer is performed when "Transfer" is set in "Safety Tracking Setting" of "Redundant System Settings" in the CPU
parameters. It is performed when the safety operation mode is either TEST MODE or SAFETY MODE.
