Hi

This is a code from a MITSUBISHI PLC..

T0
--//------------[SFTL X002 M100 K55 K1]

STFL stands for bit shift to the left..I have searched in the program but i couldn't find X002 anywhere else..

Can somebody expound this for me..

If you need the whole program, I could post it. Kindly note a comment.

Bestregards,

When 'T0' is true the shift left will be active.

In this case, the state of X2 will be recorded (on or off) and copied to M100.
The stack is 55, so m relays m100 to m154 will be the stack - the k1 means shift 1 bit at a time.

You dont need x2 antwhere else - it's there in the sftl instruction
