Configuration
1:N Connections between CP1H/CJ1M CPU Units (8 Nodes Maximum)
1:1 Connections between CP1H/CJ1M CPU Units
Specifications
Data Refresh Methods
The following two methods can be used to refresh data.
• Complete link method
• Polling Unit link method
Complete Link Method
The data from all nodes in the Serial PLC Links are reflected in both the Poll-
ing Unit and the Polled Units. (The only exceptions are the address allocated
8 nodes maximum

Specifications
Applicable serial
ports
Serial port 1 or 2. Both ports cannot be used for PLC Links at
the same time. If both ports are set for PLC Links (either as
polling node or polled node), a PLC Setup setting error (non-
fatal error) will occur and the PLC Setup Setting Error Flag
(A40210) will turn ON.
Connection method
RS-422A/485 or RS-232C connection via RS-422A/485 or
RS-232C Option Board.
Allocated data area
Serial PLC Link Words:
CIO 3100 to CIO 3199 (Up to 10 words can be allocated for
each CPU Unit.)
Number of Units
9 Units max., comprising 1 Polling Unit and 8 Polled Units (A
PT can be placed on the same network in an 1:N NT Link, but
it must be counted as one of the 8 Polled Units.)
Link methods (data
refresh methods)
Complete link method or Polling Unit link method
