Data Exchange between L

ORKS

Interface Module and CPU Module

Communication data, status data, and ID data are exchanged through registers in the L

ORKS

interface module and

link registers in the CPU module. The registers correspond to link registers as listed below:

Note:

A number 1 through 7 comes in place of * depending on the position where the functional module, such as OpenNet

inter face 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, star ting 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

ORKS

interface module, the data is transferred to a link

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

ORKS

interface module as illustrated below:
