Command Lists Section 5-1
Note 1. These commands will not be accepted and an end code of 2102 hex (can-
not write due to protection) will be returned if the Write Protection from
FINS Commands Sent to CPU Units via Networks option is selected in the
PLC Setup for a CS/CJ-series CPU Unit with unit version 2.0 or later, CP-
series CPU Unit, or NSJ Controller.
2. The Serial Gateway function can be used with Host Link FINS commands
only under the following conditions.
For more details, refer to 3-5 FINS Commands with Host Link Protocol and
the CS/CJ Series Serial Communications Boards and Serial Communica-
tions Units Operation Manual (W336-E1-05).
Connecting to the Destination PLC
Connect the destination PLC to the serial port of a Serial Communications
Unit or Board (Ver. 1.2 or later) as a Host Link Slave and use the serial
gateway mode or protocol macro mode communications.
Specifying the Destination PLC's FINS Address
• Destination Network Address (DNA):
• When a routing table is created to treat the serial communications path
as a network, the routing table associates this network address with
the Serial Communications Unit or Board's serial port.
• When a routing table is not created to treat the serial communications
path as a network, this is the unit address of the Serial Communica-
tions Unit or Board's serial port.
• Destination Node Address (DA1):
• When a routing table is created to treat the serial communications path
as a network, the node address is the Host Link unit number + 1 (val-
ues 1 to 32).
• When a routing table is not created to treat the serial communications
path as a network, the node address is still the Host Link unit number
+ 1 (values 1 to 32).
• Destination Unit Address (DA2):
Specifies any unit address other than the serial port. (The destination of a
FINS message must be an address other than the Serial Communications
Unit or Board's serial port.)
