This video is about the operands that describe the states of the zones and control and monitor the process flow. There are a total of eight operands for the entire process.
The operands are now used to define in which step the system should have which state or which state the system should assume. It is shown how to correctly define the machine states and what each operand does.
The steps for defining zones and specifying machine states and monitoring are explained first. It then goes on to explain in detail how the zone states are described using operands. You will be taken step-by-step through this process and given instructions on how to correctly define the machine states using operands. These operands play a critical role in controlling and monitoring the entire process, and there are a total of eight different operands available:
- 0 – don´t care
- I – Interlock Check
- S – Sequence Check
- D1 – Decision Path 1
- D2 – Decision Path 2
- M – Monitoring Check
- J – Jump
- C – Cancel
Once the corresponding zones, states, operands and monitoring have been defined, the basis for the subsequent programming is created.
To summarize, the operands control and monitor the process flow and ensure that the machine states are correctly defined in each step.
Stay tuned for our next video, in which we will introduce you to the assembly layer, which enables modeling with assemblies!
