PLC5 SQO Instruction

[one229 0]

Hi. I'm working on a PLC5 project where I've got only the pdf print. There's this pair of SQI and SQO rung where the sequence is controlled. It's understood that as SQI goes from false to true, the SQO will increment the sequence position to the next word in the file. In the PLC5 manual, it states that "When the rung goes from false to true, the instruction increments to the next step (word) in the sequencer file. The data in the sequencer file is transferred through a fixed mask to the destination address". My question is, which WORD in the sequencer file is transferred? Is it before the increment or after?

Lets say I'm at POS=5, as the SQI goes true, will the

- SQO transfers the word on POS 5 to destination first then increments the POS to 6

OR

- the SQO increments the POS to 6 THEN transfers the word on POS 6 to the destination.

Thanks in advance

 the SQO increments the POS to 6 THEN transfers the word on POS 6 to the destination.

if the POS = 6 then the Dest Word = Source Word[6]
