Send string via Profinet to a PLC

SimoneCosti

Goodmorning,

Actually i'm working on a project with a CRB15000, i'm programming it with Robotstudio. The Robot is mounting a camera that is going to read some serial numbers.

From the camera i receive a string similar to "SN1234|123" but it could be different.

I need to cast this string into an array of byte, so i can send it to my PLC via Profinet with SetGO.

For example:

PERS string sendString;

sendString:= "SN1234|123";

SetGO SendByte0, StrToByte(sendString{1});

SetGO SendByte1, StrToByte(sendString{2});

Ecc...

But it didn't work

I also tried with SetGO SendByte0, StrToByte(StrPart(sendString, 1, 1)) but it didn't work.

What is the correct way to do it?

Thanks everyone.

Hallo,

you have to use \char switch when converting ASCII. See documentation.

Yes, you're right
I used the format SetGO SendByte0, StrToByte(StrPart(sendString, 1, 1)\Char)
Thank you so much
