SFC 217 SER_SND
This block allows to send data from the CPU via the RS232C interface.
Here you define a range of the type Pointer for the send buffer where the
data that has to be send is stored. You have to set type, start and length.
Example: Data is stored in DB5 starting at 0.0 with a length of
124Byte.
DataPtr:=P#DB5.DBX0.0 BYTE 124
Word where the number of sent Bytes is stored.
At STX/ETX and 3964R, the length set in DataPtr or 0 is entered.
At ASCII, the value may be different from the sent length when the data is
sent that fast that not all data can be stored in the send buffer of 256Byte.
