Data Exchange between L
Communication data, status data, and ID data are exchanged through registers in the L
link registers in the CPU module. The registers correspond to link registers as listed below:
Register Address in
L W Interface Module
ON ORKS
C000h - C001h
C002h - C003h
C004h - C005h
C006h - C007h
C008h - C009h
C00Ah - C00Bh
C00Ch - C00Dh
C00Eh - C00Fh
C012h
C013h
C018h
C019h
Note: A number 1 through 7 comes in place of * depending on the position where the functional module, such as OpenNet
interface module or analog I/O module, is mounted. Consequently, operand numbers are automatically allocated to each
functional module in the order of increasing distance from the CPU module, starting with L100, L200, L300, through L700.
Example 1: Receive Data in Registers C000h and C001h
When receive data enters registers C000h and C001h in the L
register in the CPU module as illustrated below:

Example 2: Transmit Data in Link Register L*04
When transmit data is stored to link register L*04 in the CPU module, the data is transferred to registers in the L
interface module as illustrated below:
