Thank you for the help so far, but i still got the problem.
I'v tryed to reinnstall MelsecExplorer, but it made no differense.
But where do i choose to make MelsecExplorer run as a program and not as a service?
OK this is what i got:
Pc with MelsecExplorer installed and a MelsecFX2N 32MR.
To connect the PC and PLC i use the SC-09 (RS232/RS422 converter).
The SC-09 is connected to com2 on the pc and the programport on the PLC.
So my problem is how to configurate MelsecExplorer. In port setting i use this comport settings:
Port nr: 2
Baudrate: 9600
Parity: None
Flow: Hardware
Data Bits: 8
Stop Bits: 1
When i trying to connect i got these error massages:
Time Out Error (Wait=12 / got=12)
Recieve framing error
Do i have to configurate the PLC too?
