5-1 Connecting to Host Via Ethernet

Setting Node Numbers
The node number is used to identify PLCs when more than one PLC is connected to the
Ethernet. This setting is the node number used for FINS communications.
Use the left switch (SW3) to set the left digit as a hexadecimal, and the right switch (SW4) to
set the right digit. The setting range is 01 to 7E hexadecimal (1 to 126 decimal).
Setting Example:
This example is for node number 29 (decimal).
29 = 1
×
16 + 13 = 1D (hexadecimal)
Reference
•
The node number cannot be set to a value higher than 7E (126 decimal). If the node
number is set to a higher value, an error will occur and the ERH indicator in the display
will light.
•
Set the node numbers so that all the nodes in the same network are unique.
Setting IP Addresses for Ethernet Units
The IP address must also be set for Ethernet Units. Ethernet communications are not possi-
ble if the IP address of the Ethernet Unit is not set.
Set the IP address for the Ethernet Unit from the CPU Bus Unit Setup Area using Program-
ming Devices (SYSMAC-CPT, SYSMAC Support Software, CV Support Software Ver. 2 or
later, FIT20-MF501-V2, FIT10-MF501-V2, FIT20-MC601, or FIT20-MC701). Refer to the
SYSMAC CVM1/CV Series Ethernet Unit Operation Manual (Cat. No. W242) for details on
setting methods.
Ethernet Unit System
Set the system settings for the Ethernet Unit to operate on the Ethernet network as a node.
Set the system settings using a Programming Device (SYSMAC-CPT, SYSMAC Support
Software, CV Support Software Ver.2 or later, FIT20-MF501-V2, FIT10-MF501-V2, FIT20-
MC601, or FIT20-MC701).

For details on operating the Support Software, refer to the CPU Bus Unit Setup Area in
the SYSMAC Support Software Operation Manual: Networks (Cat. No. W201) and
SYSMAC Support Software Operation Manual: CV Series (Cat. No. W249).
•
Turn ON the power to the CPU Unit again after setting the system settings. The system
settings are not enabled after setting them until the power has been turned ON again.
