Posted 28 Jul 2008 Hello, I'm converting an old Moeller plc program and I need help with the "JI" and "J" instructions. I think they are jump instructions but what is the difference if they really are? Please find the picture below. Thank you. Share this post Link to post Share on other sites
Posted 7 Jan 2009 Hi, I am not very sure, but may be "I" stands for immediate. It could be that first the jump is done & after returning back, the other memory bits are set or reset which are in parallel to JI. Gud Luk. Nil Share this post Link to post Share on other sites
