PROSEC T3H
2. Expanded Functions
Regarding the network assignment, the W register is divided into 32 blocks.
(64 words per one block)
The S20 has 1024 words of scan memory. In case of the T3H, even if two S20’s are
used, the scan memory of each S20 can be fully mapped to the W register. Channel
1 S20 is allocated to the blocks 1 to 16, and channel 2 S20 is allocated to the blocks
17 to 32.
The allocation example below shows the case of all the blocks are set as “LINK”.
