SFC 216 SER_CFG
These function works for RS232C parameterization of the CPU. The
parameterization happens during runtime deploying the SFC 216
(SER_CFG). You have to store the parameters for STX/ETX and 3964R in
a DB.
Here you fix the protocol to be used. You may choose between:
1: ASCII
2: STX/ETX
3: 3964(R)
At ASCII protocol, this parameter is ignored.
At STX/ETX and 3964R you fix here a DB that contains the communication
parameters and has the following structure for the according protocols:
Data block at STX/ETX
DBB0: STX1 BYTE (1. Start-ID in hexadecimal)
DBB1: STX2 BYTE (2. Start-ID in hexadecimal)
DBB2: ETX1 BYTE (1. End-ID in hexadecimal)
DBB3: ETX2 BYTE (2. End-ID in hexadecimal)
DBB4: TIMEOUT WORD (max. delay time between 2 tele-
grams in a time window of 10ms)
Data block at 3964R
DBB0: Prio BYTE (The priority of both partners must be
different)
DBB1: ConnAttmptNr BYTE (Number of connection trials)
DBB2: SendAttmptNr BYTE (Number of telegram retries)
DBB4: CharTimeout WORD (Char. delay time in 10ms time window)
DBB6: ConfTimeout WORD (Ackn. delay time in 10ms time window)
