Setting item
Description
Port
Select Port 2 from the list box for the port.
Protocol
Click the check box to the left of the K sequence.
Time-out
When a port sends a message and waits for the response, it determines that an error occurs if it exceeds
this value.
RTS ON delay time
The RTS ON delay time specifies the amount of time the SJ-Ether will wait before actually sending data
after turning on the RTS signal. When using SJ-Ether on a multi-drop network, set the RTS ON delay time
to 5 ms or more. If a problem occurs, increase the delay time.
RTS OFF delay time
The RTS OFF delay time specifies the time that the SJ-Ether will wait until the actual data ends after the
RTS signal is turned off. When using SJ-Ether on a multi-drop network, set the RTS OFF delay time to 5
ms or more. If a problem occurs, increase the delay time.
Area code
Select "1" to switch the CPU port to the master station. The available slave station numbers range from 1
to 90 (the station numbers must not be duplicated).
Speeds
The communication speeds that can be set are 2400, 4800, 9600, 19200, and 38400 bps. When setting,
select a fast communication speed. If data errors or noise are generated on the network, change the
communication speed to a slower one.
Stop bit
For the stop bit used in the protocol, select "1 bit" or "2 bit".
Parity
For error check parity, select either None, Even, or Odd.
Finally, click the button to send port settings to the CPU and click Close.
Note: All communication speeds on each device on the network must be the same.
