Data consistency

When sending data

Once a request is initiated by a positive edge at the execute input, the data to be sent are

copied to the static memory area of the send FB. This means that once the FB call has ended,

the send data array can be written to again for the next send request on a positive edge. The

data are retained as consistent data within the send FB.

Note
During the copy operation to the static memory area of the FB, data consistency cannot be

guaranteed if the send/receive data areas are accessed in a higher priority task.

When receiving data

Once the receive request is complete, the data are copied over to the receive buffer in a block

from the static memory area of the receive FB. This means that once the FB call has ended,

either all data are entered in the receive buffer (newDataReceived = TRUE) or no data are

entered in the receive buffer (newDataReceived = FALSE).

Note
During the copy operation from the static memory area of the receive FB, data consistency

cannot be guaranteed if the send/receive data areas are accessed in a higher priority task.
