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.

Address

250

251

(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.

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. ( Page 41 Parameter Setting)

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.
