In this series, we have seen that a Function Block has many practical real-world automation applications.
I showed you how an FB and its associated data block are configured.
In this video, I will show you how to configure a single block in the step seven programming environment to perform the function of a sequencer, and how I can use an FB to control the execution of the sequencer logic
In this video, I will show you how to configure additional input and output parameters in the DRUM sequencer block in the Sequencer FB, and how to configure the DRUM sequencer block to execute the recipe for the batch process.
In this series, we have seen that a Function Block has many practical real-world automation applications.
Today, we will continue to develop the example of the small batch process with a large mixing tank with an agitator, four-ingredient addition lines, and a bottom valve.
In this video, we will configure the transition logic for Step 2.
I will use the same construction as for the previous rung, but I will change the “compare equal” instruction to compare the step number to two. I have added the “BATCH_START” bit to a “SET OUTPUT” coil as before.
