Connecting to a Node
CVM1/CV-series Host
Link Unit
Set the communications parameters for the port to be used (port 1 or 2) with the
rotary switches, DIP switch, and CPU Bus Unit System Setup of the CVM1/CV-
series Host Link Unit (CV500-LK201).
Setting the Node Number for Communications Port 2
When multiple PCs are connected to the host computer, a node number is as-
signed to each PC for identification purposes. Decimal numbers 0 to 31 can be
assigned as the node number of communications port 2. Set the tens digit with
the left switch and the ones digit with the right switch.

x 10
Note 1) Do not specify a node number higher than 31. Doing so results in a error and
lights the ERC2 indicator on the display panel.
2) Since the Controller Link Support Software and the Host Link Unit are al-
ways connected on the one-to-one basis, the node number can normally be
0.
3) The node number of communications port 1 is fixed at 0.
