Carriage Return and Line Feed. Siemens ASCII.

[DLMUK]

Hi,

I need to send a command from a S7-300 with a CP341 in ASCII format (RS485). I can get the command to send fine, what I need to do is add carriage return and line feed on the end.

I have found conflicting information from a few sources, my setup is using ladder and I simply send the value of a tag stored in a DB. What I need to send is:

01:#028<CR><LF>

Would I use

01:#028$0D$0A

OR

01:#028$R

Some manuals suggest that the Siemens will automatically send LF unless I explicitly tell it not to. Which I haven't.


Thanks,
