HMI and SCADA and PLC09 Jul 2010 08:47 am

If you want to design MMI/HMI to communicate with PLC ,please read article.

INTRODUCTION
• These control systems allow a much more interactive than ever before.

• The main purpose of the HMI a simple graphical user interface to the process.

• These devices are known, the number of names
-> Touch Screen
-> Exhibitions
-> Man Machine Interface (MMI)
-> Human Machine Interface (HMI)

HMI plc

• Provides a simple user displays used to determine the condition of the machine and SIM
PLEs settings.

• The most commonly used,
-> Display machine errors
-> View the status of equipment
-> Allows manual start / stop cycles
-> Monitor the first part

• These units offer certain advantages, such as
-> Color coding for easy identification (eg red for angry)
-> Images / icons allow quick recognition
-> Use of images makes the problems of illiteracy
530
-> The screen can be changed to allow different levels of information and access (more…)

I would like to overview the Omron PLCs in SYSMAC CS1 Model ,what is new?,How to? please see below.
High Performance
Maximum power controller
To provide a background that the production capacity for sudden changes in demand, or machines that are easy on the fact that competitors are created according to market, a top speed controller, can provide the required power to support these needs will need to create a distinction must be tolerated. SYSMAC CS1 PLC reduced the maximum I / O response data and control functionality, and furnished a lot of time on the processing machines to provide a more precise control.
Human Efficiency
omron plc sysmac cs1

User-friendly environment for development

This facilitates the development of complex programs, I’m next to Windows-based integrated development environment that the new controls provided with a series of commands. Structured programming function has been improved to re-programs with greater efficiency and thus reduce the workload and reduce costs.

PLC software and PLC programming06 Jul 2010 10:41 pm

When you hear the word “Lite” software, and you tend to think that software is really useful. Depending on your needs, this may not be the case with Siemens STEP 7 Lite package. Four major constraints in the STEP 7 Lite verses advanced STEP 7 package are:

Support for SIMATIC S7-300 PLC, C7 all-in-One HMI and PLC are limited, intelligent CPU ET200M Distributed I / O family. So no programming S7-200 or S7-400 series PLC.
No network at all. Remote I / O racks (IM modules) are supported, but not for Profibus DP, even if you have a DP port on the CPU.
No support for multi-projects or HMI integration.
No communication processors (CP) or functional modules (FM) supports.
If you would like further information, see our chart of differences between the STEP 7 program packages. Thus, there is quite a big limitation, Step 7 Lite software to further your reading this review at the end of May.
