Setting Node Number Setup Switch - Omron V670-H11 User Manual

3-1-1-4 Setting Node Number Setup Switch

♦ Node number
To connect several controllers to one host device using a link adapter etc., the host device needs to identify each of those controllers.
The number to identify them is referred to as node number. A unique node number must be assigned to every controller.
The command and response of 1:N protocol have the node number. So, unless the node number is assigned appropriately, any commu-
nication cannot be made.
♦ Setting node number
Set the node number with the two node number setup switch. SW1 (left) is for an upper order and SW2 (right) for a lower order. Avail-
able number range is from 00 to 31 as shown below.
