PhaseManager Questions and Answers
Question Answer
How can I get the highest performance possible
from my equipment? You have to measure equipment performance to improve it. The state model gives you a
way to measure the status of your equipment. With that data, you'll be able to calculate
the efficiency and performance measures that you want.
If you use PhaseManager software across your plant, you have consistent data from
equipment to equipment.
How can I cut the cost of integrating my
equipment into the plant? Clear structure and consistent tags make it a lot easier to plug the equipment into your
plant and set up communication right away. Equipment up and down that line share
data using the same tag names. And all equipment communicates with higher-level
systems in the same way.
How can I make it easier to maintain the code? A state model helps you lay out the general functions of your equipment. We found that
the best programmers use a state model as the heart of their code. A state model serves
as a map for the code. With a clear structure, you'll know just where to look for the
piece of code that you want.
How can I give my operators a clean, intuitive
HMI? A state model lets you make all your equipment behave the same. Your HMIs can then
show consistent equipment conditions across the plant. When an HMI says that the
equipment is idle, running, or holding, your operators will know exactly what that
means.
