POU header
All input and output variables used for programming this function have been declared in the POU
header.

the MCU port 1. The characters are copied to the array awSendBuffer. awSendBuffer[0] is
reserved for the length of the string to send.

if (DF(bSend)) then
sResult:=SendCharacters(1, sSendData, awSendBuffer);
end_if;
