Posted 19 Sep 2016 (edited) Hi I have a device that requires ascii string to be sent to read or write specific variables. Below is the format I am using a m241 and serial port 2 and connecting by 485 2 wire. Only n would be used as a variable to change speeds. only problem is I cant find how to send the whole string. Write_var seems to only let me send a single word. any help would be appreciated. thanks Edited 19 Sep 2016 by Rodz Share this post Link to post Share on other sites
