B's line of PLC's. At each step of the sequence, data is transfered from a "source" word, to a "destination". Let's use B3:1 through B3:5 as the source. We'll use B3:10 as the destination. At step one, the data that is contained in B3:1 will

Application Specific Instructions. • Bit Shift Instructions – Allows for basic shift and rotate operations. – Bit Shift Left (BSL). – Bit Shift Right (BSR). • Sequencer Instructions – Useful for outputting or comparing a sequence of data on a recurring basis. – Sequencer Output (SQO). – Sequencer Compare (SQC). – Sequencer
If you want to change the mask according to application requirements you can use a mask word or file. (If the mask is a file, its length will be equal to the length of the sequencer file.) The destination is the address of the input word or file for a SQO to which the instruction moves data from its sequencer file.
The PLC on your trainer includes the following sequencer instructions: • the sequencer output (SQO) instruction;. • the sequencer compare (SQC) instruction. The SQO instruction transfers data from a programmed sequencer file, through a mask, to a destination file. This instruction is used for the sequential control of.

15 Oct 2015 SQO. SQO instructions are primarily used in sequential machine control applications. where machine operations are repeatable from one cycle to the next. This. instruction does not lend itself well in operations where the machine is often. FILE. #N7:0. reconfigured for different short run applications. MASK.
Copyright © 2002 Delmar Thomson Learning. Sequencer Output Instruction (SQO). SQO is an output instruction. Each false to true transition causes the SQO instruction to increment to the next sequence step. Sequencer steps are stored in a reference data file. Copyright © 2002 Delmar Thomson Learning. SLC 500 PLC
Do you not have help files or examples for SQO and SQC in the program youa re using. The RSlogix examples I saw made it fairly clear that the file and destination are not to be the same. Your Sequencer will need three steps therefore you will need to false to true transition the SQO instruction three times.
