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.
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/module labels (extension base unit).
• 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.
When only the tracking block No.3 has no setting
Local devices, global labels, local labels, and module labels (extension base unit) are transferred only once in
one scan. Even when the same local devices, global labels, local labels, and module labels (extension base
unit) are specified in multiple tracking blocks, the overlap does not affect the data capacity to be transferred.
