Device variable for CJ-series Unit
Port 1
*_P1_TransErrSta
*_P1_TransErr
*_P1_TfsErr
*_P1_TfrErr
*_P1_TrErr
There is no specific
device variable for CJ-
series Unit to reference
the number of retries.
When you reference
the number of retries,
refer to bits 08 to 11 of
*_P1_TransErrSta.
*_P1_FCSErr
*_P1_CmdErr
*_P1_TimeoutErr

Port 2
*_P2_TransErrSta
*_P2_TransErr
*_P2_TfsErr
*_P2_TfrErr
*_P2_TrErr
There is no specific
device variable for CJ-
series Unit to reference
the number of retries.
When you reference
the number of retries,
refer to bits 08 to 11 of
