7. Error cancel
To cancel the error status, this bit will be turned on (will be set to ‘1’).
If this bit is turned on, the error status will be canceled.
At the completion of error status canceling, turn off this bit (set this bit to ‘0’).
Note: If the cause of the error is not eliminated, the error signal will be output again.
8. Transmission frame check request
Use the transmission frame check request to check whether the output data is transferred to the S-LINK V
unit. To send two different outputs to the same address, use this request signal. This is because if the next
data is set before transferring the previously set output data to the unit, the previously set output data will be
ignored. However, after setting output data, if this request signal is turned on (set to ‘1’), completion of trans-
mission frame check signal will be turned on (will be set to ‘1’) after transferring the set output data to the unit.
Using the program, check whether the completion of transmission frame check signal is turned on (set to ‘1’),
and then set the next data to prevent an output data transfer error.
To repeatedly use the transmission frame check signal, turn off (set to ‘0’) the transmission frame check re-
quest, and then check whether the completion of transmission frame check signal is turned off (set to ‘0’). Af-
ter that, turn on (set to ‘1’) the transmission frame check request again.
