In addition, the mask input is to receive the address of the mask or the data block of which the instruction will move the data sequentially before relaying it to the output. The file parameter is the first input parameter showing the address of the reference sequencer file. The instruction takes the input data from the file, array, and data block and sequentially relays it to the outputs to trigger them sequentially.įigure 2 shows the block of the sequencer output instruction showing input and output parameters. Sequencer output instructionįigure one shows the block diagram of the process. So we are going to give one example for each case showing how to code the equivalent to the sequencer output instruction in the PLCs that does not support this instruction.

Before starting the article, we need to mention that, some controllers like Allen Bradley have sequencer output instruction and some has not like Siemens. And practice some examples with the simulator as usual. In this article, we are going to introduce how to implement sequencer output instruction. So instead we can use a new technique to trigger these outputs in sequence using one instruction which will save the effort of programming and space of memory.

In the normal or conventional technique of programming we deal with them individually or one by one which takes more effort in programming and much space of memory. In another word, when we have some output that is repeatedly run in sequence.

Hi friends, today we are going to learn a good technique to run multi outputs in sequence.
