Parameterization
The parameterization happens during runtime deploying the SFC 216
(SER_CFG). You have to store the parameters for STX/ETX, 3964R, USS
and Modbus in a DB.

Return value (0 = OK)
All time settings for timeouts must be set as hexadecimal value. Find the
hex value by multiply the wanted time in seconds with the baudrate.
Example: Wanted time 8ms at a baudrate of 19200Baud
Calculation: 19200Bit/s x 0,008s
≈
154Bit

(9Ah)
Hex value is 9Ah.
Here you fix the protocol to be used. You may choose between:
1: ASCII
2: STX/ETX
3: 3964R
4: USS Master
5: Modbus RTU Master
6: Modbus ASCII Master
