Serial communication

RobotStudio
1

Hi!
I´m having a problem when opening an com port in robotstudio and cant figure out what im doing wrong.
What I´m trying to achive is to send information from a vision program and everything is working except the communication

I´m trying to open COM1 whit the following code:

VAR iodev channel;

VAR num out_buffer{20};
VAR num input;
VAR robtarget target;
Open “COM1:”, channel\Bin;

Close channel;

The error code I got is an file open error but i don’t want to open a file, i want to open COM1

Please help me with what I´m doing wrong.

The com port is the com port on the controller and not on the pc (never tried it but don’t think it’s possible if you aren’t on a real controller. And a better solution if possible would be using socket communication over ethernet. Have done that myself against a vision system
