Word Data Start Address Setting Function
This function shortens the word transmission cycle time by setting the start address of word data transmission.
Unregistered addresses between address 0 and the registered address are accessed during word transmission. Although this
access takes extra time for word transmission cycle, setting the number of word data points and transmission start address
enhances the efficiency of transmission.
This function can be used for word data only. This function does not affect the target input and output
addresses of bit data.
Setting method
For this function, from the CC-Link IE TSN configuration window, set "Word data start address setting" in the "Parameter of
Slave Station" window. (
Precautions
• The I/O signals on and after the word data start address are stored in AnyWireASLINK word input signal (RWr20 to
RWr21F) and AnyWireASLINK word output signal (RWw20 to RWw21F) of the remote register.
• If the word data start address setting function is used, the transmission cycle time may be different than normal. When
using the word data start address function, refer to the following remote buffer memory for the transmission cycle time.
(1) Registered address (word slave module)
(2) Access to unregistered addresses existing before the registered address causes extra time for word transmission cycle. (Word data points setting: 512
words (256 input words/256 output words))
(3) When the word data points setting is 4 words (2 input words/2 output words) and the word data transmission start address is set to 250, the addresses
targeted for access will be 250 and 251 only.
