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.
