What is HMI Human-Machine-Interface-Screens

 What are Human Machine Interfaces? HMI

HMI is considered an interface that allows humans to interact with the machine. Examples of HMI a machine with a touch display,

What is  HMI?

Communication between the processor and HMI (human-machine interface) is an important topic

As well as the creation of an operator interface. The chapter includes the procedures to be attached

Computers as HMI devices from AB and Siemens 1200 to Compact Logix processors

Processor. The graphic control package used is A-B's RSUV ME and Siemens Win CC. other

Packages exist and were not excluded based on their capabilities. Used are among people

More common and popular are used today.

Historical Panel Design

The design of an operator panel requires a lot of coordination with the PLC's programming
And the design of the machine is being controlled. Before computer-designed systems, there
There were separate component systems that we're hard-wired to control devices inside the panel.
SA-101 Human Machine Interface for Process Automation System
ISA-101 (officially ANSI / ISA-101.01-2015) is the HMI specification to describe it appropriately
Development of HMI Panel. The specification is under development and should be referred to

Because it may contain input for your HMI design.

Hardware to implement software
The following Siemens panels are available for selection to replace the various panels above.
The software allows the design of these 'soft' panels to be customized to represent all the designs shown
up. Siemens, which offers a full offering of hardware operator interface units

Complementary to software requirements.

Since 1973, an HMI that works after months of development
In 1973, I was intensely involved in a project involving HMI for three stations for one glass.
Manufacturing line. The program was written entirely in an assembler on a 16 k machine (IBM)
System 7). The HMI portion was to have six screens for the entire line including three stations.
What happened to that project was a complete outburst of the need for a manual back-up
Can automatically ride the imagination of the original system. Was the only one to make a response
A manual back-up system that expanded the original six screens to 66 screens. Along the way, a
The complete diagnostic system was also developed because there could not be electricity and operators
It is expected to keep the line running without good data about the sensor on the machine.
And if one is not working correctly. Eventually included about the HMI program
23k assembly statements were found in 66 individual over-late programs running in the computer's 384-word overlay area.

The program was a tree-designed system asking operators a range of options
Which an operator successively walked out of a branch of the tree. In the end, it worked and
Was accepted by operators and plant engineers. It went a long way and covered my time
For more than a year. Hopefully, the lessons learned from such experiences will be
Useful for future engineering efforts.

One of the two was a conflict between learned production and fictional original design
Which emphasizes full automatic control. Manufacturing was not ready for the environment
Complete automation of theorist. If a production supervisor finds it more beneficial
The destination of the glass should be at a take-off point on the right instead of the left side, that
He wanted flexibility. The automated system did not offer that kind of flexibility and it refused
To use the system until it is developed for your needs. The other lesson was the diagnosis.
Reporting. The operation was not successful until every switch was turned on for the glass
Tracking) and these switches were constantly in a mess due to the moving glass. this
Only after a dedicated line on each display was the active status of any broken switch shown and
Its precise position tracking system was allowed to function.

Since 1998, an HMI system split

In 1998, I worked on a system for a steel company that saw the project split.
Multiple tasks with four engineers working simultaneously on two PLC / HMI programs.
PLCs were mod icons and HMI was Wonderware. I was responsible for this project
PLC program for process control. My counterpart from India worked on the HMI part.
Two individuals programmed the steel movement portion of the project from their office

Toronto Canada. The hardest part was the HMI part for the steel movement.
