Hello,

I have a question on my HNC electrical and electronic engineering assesignment which has me stumped after hours of looking through PDF manuals.

"Explain the sequencing system operated by a Mitsubishi Fx1 PLC and suggest possible problems that may be caused by this?"

I know that sequencing is the order in which instructions are performed in an algorithm, the only thing i can think of is that sequencing system in a Fx1 is somehow flawed.

I just cant find any information on this, please can you help me out with this.

Might they be referring to STL/SFC programming?

The HNC course questions are flooding in again - and once again they are poorly thought out questions.

I will refer you to this recent post on another PLC site.
