Troubleshooting Using Indicators					Section 9-1
Node Cannot Participate	The following table describes the LNK and M/A indicators when a node can-

	Data link participation depends on the Controller Link Unit operating normally
	and participating in the Network. Refer to Troubleshooting with RUN, ERC,
	ERH and INS Indicators earlier in this section and check Unit operation before
	using the following table.

Troubleshooting of Other Errors

To configure a network that uses a node address higher than 32, all nodes must be CS1W-CLK21-V1, CJ1W-CLK21-V1, or 3G8F7-CLK21-V1. The Wired Network 62 Node Enable Bit in the DM Parameters Area must also be turned ON (62 nodes max.) for all nodes. If the nodes are set differently, the network will not be configured correctly. If the settings are incorrect, the follow- ing problems will occur.
