Setting Unit Numbers
The unit number is used to identify each Unit when multiple CPU Bus Units are mounted to
the CPU Unit.
Use the left switch (SW1) to set the ten's digit, and the right switch (SW2) to set the one's
digit. Set between 00 and 15 decimal.
Setting Example
This example is for unit number 12.
· The unit number cannot be set to a value more than 15. If the unit number is set to a
Reference
value higher than 15, the ERH indicator in the display will light.
· When more than one CPU Bus Unit is mounted to a single PLC, set each Unit with a
unique unit number.
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 ）
