The data will be converted as shown below if the Convert Endians Check Box is selected.
•
Data Length: WORD (16 Bits)
The endianness will be converted every 8 bits.
Example: 12 34 → 34 12
•
Data Length: DWORD (32 Bits)
The endianness will be converted every 16 bits.
Example: 00 01 0B 0A → 0B 0A 00 01
Timing of Device Data Transfers
Device data will be transferred when the transfer trigger condition is met and the Transfer in Progress
Flag is OFF. The data will therefore not be transferred if the device data transfer trigger for one group
occurs when device data is being transferred for another group.

processing
If the rising edge or falling edge is set as the trigger condition, the trigger address will not be auto-
matically turned ON or OFF by the system after the trigger condition occurs. If a cyclic trigger is set,
however, the triggers will be sorted with the shortest cycles first and transfers will be executed in order.
An example of using cyclic triggers is provided below.
