Run on config fault

No

If this parameter is set to “Yes” the IEC application will not be prevented from switching to RUN state, independent from possibly existing configuration errors of the particular COM port.

Yes

Transmission rate

9600 baud/sec

Sets up the transmission rate to use for the COM port.

19200

38400

57600

115200

Parity

None

Sets up the parity to use for the COM port.

Odd

Even

Data bits

5 data bits

Sets up the number of data bits to use for the COM port

6 data bits

7 data bits

8 data bits

Stop bits

1 stop bits

Sets up the number of stop bits to use for the COM port.

2 stop bits

Flow control

No flow control

Allows to switch between different flow control modes (either RTS/CTS hardware or Xon/Xoff software or none). This setting is only valid for RS-232 serial interface mode. In case RS-485 is used for parameter “Serial interface”, flow control must set to “No flow control”. Otherwise a configuration error is triggered.

Hardware RTS/CTS

Software Xon/Xoff

Boot parameter Serial interface

RS-232

Allows to switch between RS-232 and RS-485. Due to technical reasons, it’s not possible to dynamically switch between the modes. This means, a reboot (or power cycle) of the PLC is required to activate the particular setting once changed.
