SCD_TRACYCL
Initializes a data object, whose data is transmitted immediately once.
The object has the following structure:
H+0: Object number
H+1: Number of data bytes and data format
H+2: Number of the variable H" where the data to be sent begins
H+3: Status of the transmission command
The following standard SEW structures are available for the _SBusCommDef state-
ment:
INFORMATION
Prior to transmitting acyclical telegrams, the SBus must also be activated with
_SBusCommOn or _SBusCommState.
MOVIDRIVE
®
B
: The IPOS
plus®
program waits at this command until the message
has been sent, but for a maximum of 10 ms. Users can only monitor whether the tele-
gram has been sent correctly by evaluating the state (H+3) or the expected response.
