Hello,

I am setting up a positioning project with CB-1241 RS-485 Communication Board on a S7-1200.

I was able to get some data out but I believe this is not the correct position data I should get because the data keep jumping between different values.

Attached files are the setting I am currently using, along with the docx file from the sensor's vendor information on the protocol.

I noticed that the CONDITIONS.START is already set to detect 'STX' message which is the same as start of message frame from the sensor. However, when I set the CONDITIONS.END to detect "ETX" I received nothing. The length count for the message is 0. Meanwhile if I set the CONDITIONS.END message to default then I got the data jumping from different values to another.

Please point me to the right direction.

Thanks,

Alex
