Hi Aram. Go to this link <https://sites.google.com/site/classicladder/> for a complete information on Classic Ladder stand alone version (the original one). The site is the official supported by the French author Marc Le Douarain. I suggest to you to use Modbus RS485 or TCP/IP (that is a built in function) if you want to interface Classic Ladder with the field I/O. The last vesion on the site is not exactly the same included in LCNC of course. The LCNC integrated version has all the connectivity to HAL that the original version doesn't have. I tried the stand alone version and it is working fine as a softplc . As already clarified previously Classic Ladder has some limitations (i.e. floating point variables, non retentive variables value, Modbus connectivity number of instances limitated ...) but in any case it is a plus into LCNC and it is usable in stand alone mode if needed.
