Hello, I have installed ladder Builder for KV Ver. 1.50 on a Windows XP professional and it works well on PC but when I intend to upload current program or to download any program to PLC it just appears a screen with text " Communication error occurred. Check for Communication Setting and Connection Lines" Is this problem due to newer Windows version? or do I need to un-install Windows XP Pro and install Windows 95? By the way, I made 2 different comm. cables direct and inverted type.
Thanks in advance.
