Hi, I am in need of help to fix a software for positioning system on a sawmill. The PLC I use is a CP1E, positioning is done with a E6C2 - 600 pulse incremental encoder. Controlled by weintek HMI. I am having trouble getting my positioning to be exact and sometimes it can vary by as much as +-1/8".  I put the code in attachment, if you look at the "auto_down" section, that would probably be the simplest place to start looking.  I would much appreciate any feedback on possible flaws in my coding or the way I put it together. Thank you, Stephane 4221 V2.4 (2020).cxp

Hi, I was wondering if there is a basic cx programmer version that is made for clients to update their plc without them having access to the entire code. I have many customers in different country's and pushing out new software updates for them can be a problem. I'm using a CP1E plc usb version. thanks!
