FB 100: Sending data word areas
Before you call FB 100, the data block containing the link list must be
open. The function block SEND-DAT requires the number of the CPU on
which it is called in order to evaluate the information contained in the
link list.
If the SEND function (OB 202) is not executed correctly in the function
block, the error or warning number is transferred to the output
parameter ERWA and RLO is set to 1.
If the input parameter CPUN (CPU number) is illegal, ERWA has the value
16 (bit no. 4 = 1).
The function block SEND-DAT uses flag bytes FY 239 to FY 251 as
scratchpad flags.
