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).

-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.
