Box)
Order number and position of the selected I/O module are shown at the
titlebar.
Following select boxes are shown in the dialog box:
Select box Available settings
Baudrate 1200 Baud / 2400 Baud / 4800 Baud /
9600 Baud* / 19200 Baud
Data frame 7 Databits, Even Parity / 7 Databits, Odd Parity /
8 Databits, No Parity* / 8 Databits, Even Parity /
8 Databits, Odd Parity
Stopbits 1* / 2 Number of stopbits
Standard (see mapping-tables in the coupler- /
controller-manual)
Output format
Alternative* (see mapping-tables in the coupler- /
controller-manual)
Data bytes (BK) 3* / 4 / 5 Number of data bytes (see mapping-tables
in the coupler- / controller-manual)
Disable Hardware handshake is not active RTS / CTS
Enable* Hardware handshake is active
RTS is set if receive buffer of the module
contains more than 114 characters.
RTS is reset if receive buffer of the
module contains less than 104 characters.
If CTS is set the module does not send
any data.
Normal* State byte and data bytes are transmitted
in the same KBUS cycle
Copy State Byte
Retarded The state byte is transmitted one KBUS
cycle later after data bytes are transmitted.
This causes a lower data transmission
rate.
