Adding Nodes Using a Repeater Unit Section 10-1

10-1-2 Procedure for Adding Nodes

Setting the Repeater Unit

Check the operating conditions and setting status of the existing network.

Set the baud rate and terminating resistance switch on the Repeater Unit.

(1)Number of nodes registered in network and node addresses

(2)Baud rate setting

(3)CS1W-RPT01 Repeater Unit connection

(4)Data link mode when data links are active/inactive

(5)Wired Network 62 Node Enable Bit setting in the DM Parameter Area

(6)Ladder program (program that includes the new nodes)

Setting the additional nodes

Prepare the nodes to be added.

Set the Control- ler Link settings for the new no- des.

Turn ON the power to the new nodes.

Set the DM Area parameters.

Turn OFF the power to the new nodes.

Connect the communications cables.

Turn ON the power to the Repeater Unit.

(1)Set the baud rate to match the settings for the existing network.

(2)Set the terminating resistance switch: Turn ON the terminating resistance for the Repeater Unit if it is at the end of the segment.

(1)Set the polling/polled node setting to Polled.

(2)Set the Wired Network 62 Node Enable Bit to match the setting for the existing network.

Check that the error indicators (ERC and ERH) are not lit. (When the node address is set to 33 or higher, the ERC indicator may turn ON. Turn ON the Wired Network 62 Node Enable Bit (to enable 62 nodes), turn ON the power again, and check that the ERC indicator is OFF.

Return the polling/polled node setting in the DM Area parameters to Polling.

10-1-3 Precautions when Connecting Nodes Using a Repeater Unit

When data links are active in the existing network, check the following items before adding nodes to the network. If the inappropriate data link tables or parameters are set, the system may not operate properly.

•If the new node will participate in user-set data links, make sure that the appropriate data link tables are set in the corresponding nodes.

•If the new node will not participate in user-set data links, make sure that the data link tables of the corresponding nodes are deleted.
