Chapter 8: Memory Address on the ME-NET
The ME-NET employs a system for addressing individual memory banks in all of the connected
equipment by allocating address throughout the ME-NET. Therefore, the top address in any link area
which will contain in the data link parameters and memory addresses used for computer link
instructions must be a valid memory address in the ME-NET.
The relationship between memory addresses in Sharp PCs (JW20/JW20H/JW30H) and those on the
ME-NET are shown below.
8-1 Memory address for data links
The memory addresses
(8)
on the ME-NET correspond to the file addresses
(8)
in a Sharp PC (JW20/
JW20H/JW30H).
(1) Memory address map (against JW20/JW20H)
- For details about the address range of relay link, register link, and the JW-21MN flag, see page
11-11 in this manual.
- The addresses that can be used vary with PC model in which the JW-21MN is installed and with
the memory capacity of the PC. For details, see the instruction manual for a particular PC.
