• The allocation of the areas available for the P/W PC LINK 0 and P/W PC LINK 1 in the CPU are specified
using the system registers as follows ;

Notes :
• Link relays(L) are assignments performed in units of words( 1 word = 16 bits).
If the system register number 40 is set to 64, all the relays(1,024 points: L0 to L63F) can be
used as the relay link area for the P/W PC LINK 0.
• The send area is used for sending data to the other Programmable Controllers in the PC Link
Mode in the same network. The rest area of the PC Link Area is automatically allocated as the
receive area.
*If the send area size is set to 0, all of the area is used as the receive area.
*If the send area size is set to the maximum value,
send link relay area
send link data regiseter area : 127 link data registers are used as send link data registers.
• Even if 128 link data registers are available for use as the PC Link Area, a maximum of 127 link
data registers can be used for the send area.
• Make sure that the send area allocated is within the range of the specified PC Link Area.
• Within the same network, the send area addresses must not be overlapped.
