1. Confirm link unit settings. (After making settings, cut power to the PLC.)
2. Go to the editor (V-SFT) and confirm the settings in the [Comm. Parameter] dialog in
the [System Setting] menu.
3. If errors only occur from time to time, it is possible that there is a noise-based
communication error.
* If you still cannot solve the error even after following the suggestions above, contact your
local distributor.
