Registers
The OpenNet Controller CPU module exchanges communication data through the registers in the L
module. The register addresses are listed in the table below:
Address
Data register
C000h - C007h
(8 bytes)
Data register
C008h - C00Fh
(8 bytes)
C010h - C011h reserved
C012h Error data
C013h I/O counts
C014h - C017h reserved
C018h Software version
C019h Expansion module ID
C01Ah - CFFFh reserved

Description
Interface
Module
Allocate network variables to these
addresses to exchange data between the
CPU and interface modules.
— Do not write data into this area.
Use this address to read error data from the
interface module.
Use this address to store the byte counts of
transmit/receive data selected in WindLDR
Function Area Settings.
— Do not write data into this area.
Use this address to write the user applica-
tion software version number (use any num-
ber other than 00h).
Use this address to write the user program
module ID (use a number 40h through 7Fh).
— Do not write data into this area.
