Note 1. Applicable PLCs: CV = CVM1 and CV-series PLCs, CS/CJ = CS-series
and CJ-series PLCs, All = All models of PLC.
2. Errors indicated by error codes 0101 to 0116 are recorded only when the
frame was discarded because transmission was impossible.
3. Error code 0230 hex is only recorded for Controller Link Units with unit ver-
sion 1.2 or later.
