5.5.5 Tracking Block And Tracking Trigger
(1) Tracking Blocks
(a) Tracking Block Overview
The internal device tracking range can be divided into multiple blocks, i.e.,
tracking blocks (tracking block No. 1 to 64) at the tracking settings in the
redundant parameter settings of GX Developer.
(b) Tracking the Tracking Blocks
Set whether the tracking block will be tracked or not with the data tracking block
specification trigger (SM1520 to SM1583) that corresponds to the target tracking
block.
When the data tracking block specification trigger is turned ON, the device data
set to the corresponding tracking block No. will be tracked.
