37.2 Tracking Transfer
Tracking block and tracking trigger
The devices or labels of a specified range is transferred by setting a range of devices or labels to be transferred for each
tracking block and turning on the tracking trigger which is assigned for each tracking block. Note that only standard devices/
labels can be transferred for each tracking block. (Safety devices/labels cannot be transferred for each tracking block.)
Tracking block
A tracking block is used for setting a tracking transfer range of global devices and whether or not to transfer local devices/
global labels/local labels.
• Up to 64 blocks (No.1 to 64) are available.
• Up to 2048 devices can be set in a block. Up to 2048 devices can be transferred in a single tracking.
• The available capacity of tracking devices or labels is 1M words per block.
Ex.
When only the tracking block No.3 has no setting
Global labels, local labels, and local devices are transferred only once in one scan.
Even when the same global labels, local labels, and local devices are specified in multiple tracking blocks, the
overlap does not affect the data capacity to be transferred.
