Time monitoring
The input tTimeOut is used to monitor the transfer time of the data received from the frequency
inverter.
·
With a time > t#0ms the monitoring is activated, otherwise it is deactivated.
·
The monitoring time must be adapted to the cycle and task time of the process data object
CAN2_IO.
Status messages
The status outputs nStateDataTo82 and nStateDataFrom82 indicate the current state of the send
and receive objects.
·
If an error occurs, an error number will be indicated and the corresponding message output
bFail_DataTo82 or bFail_DataFrom82 will be set to TRUE.
·
The status and message outputs can be reset by setting bReset to TRUE.
·
The last message/error number is saved in an internal variable (nLastMessageNo or
nLastFailureNo).
Selection of boolean control signals and output of boolean status messages
·
The FB L_8200CtrlWord is used to select the control word to be transmitted as boolean
control signals.
( ^ 3−15)
·
The FB L_8200StatusWord is used to divide the receive status word for evaluation and further
processing into individual boolean status signals.
