All time settings for timeouts must be set as hexadecimal value. Find
the Hex value by multiply the wanted time in seconds with the bau-
drate.
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
At ASCII protocol, this parameter is ignored.
At STX/ETX, 3964R, USS and Modbus you fix here a DB that con-
tains 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)
DBW4: TIMEOUT WORD (max. delay time between 2
telegrams)
The start res. end sign should always be a value
< 20, oth-
erwise the sign is ignored!
With not used IDs please always enter FFh!
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)
