Example:
When the transmit and receive bytes are set to 3 using
WindLDR
(on the Open Bus page selected from Configure > Func-
tion Area Settings), only 24-point type declared network variables (nv_i24 and nv_o24) and the network variables shown
in the table below can be used. Then, link registers listed below can be used for transmission and receiving.
