Data Links Won't Start
For the data links to operate, first the SYSMAC LINK Units must be operating
and participating in the network. First, check the LNK indicator status by refer-
ring to RUN, ERC, ERH, and INS Indicators above, and then use the following
table.
Probable cause
In this case, the error log (error code 021D Hex) will be stored. Refer to 8-2
Error Log for details.
Nodes Not Participate in Data Links
For nodes to participate in the data links, first the SYSMAC LINK Units must
be operating and participating in the network. First, check the LNK indicator
status by referring to RUN, ERC, ERH, and INS Indicators above, and then
use the following table.
Probable cause
In this case, the error log (error code 021D Hex) will be stored. Refer to 8-2
Error Log for details.
Remedy
---
Add the local node to the refresh parameters, then
start the data links.
Refer to the PLC operation manual, eliminate the
error, and start the data links. If the error reoccurs,
replace the CPU Unit.
Correct the data link tables, and restart the data links.
Either use the automatic setting or increase the set-
ting manually (see note).
