• Frame size
- ASCII communication : max. 128 bytes
- Hex communication : max. 256 bytes
• Link relay (L)
- It’s a flag to indicate whether a user defined frame is received in the order set by the user.
- If the received frame is matched with the declared frame in frame list number 3, L003 starts blinking
(0 → 1 → 0).
• When frame receiving is done, MASTER-K120S main unit check if there’s any match between the received frame
and the declared frame in frame list. If there is, let the Link relay L(n) flag blink and save the received data in the
assigned area.
