Station number setting for a PLC link
The station number can be set within a range of 1 to 16. For details on setting station
numbers, see "Setting Station Numbers" on page 167.
#1 #2
A maximum of 16 stations can be connected in a PLC link
# Station number of PLC
NOTE
•
Make sure the same station number is not used for more than one of the
PLCs connected through the PLC Link function.
•
Station numbers should be set sequentially and consecutively, starting
from 1, with no breaks between them. If there are fewer than 16 stations
linked, set the highest station number to reduce the link transmission cycle
time. See "Setting the Highest Station Number for a PLC Link" on page 232.

8.7.2 Link Area Allocation

To use the PLC link function, link areas need to be allocated. Set the allocations for both the
link relays and link registers using the system registers of the CPU.
Link areas consist of link relays and link registers and are divided into areas for PLC link 0
and PLC link 1. A maximum of 1024 link relays (points) and 128 link registers (words) can be
used in the PLC link areas.
