Hi guys

I want to upgrade the hmi on a stand alone system.
Currently I have a pc running intouch v7.1 talking
through S7 IO server software to an siemens S7313c
plc over ethernet. The pc display is a 15" touch screen.

I want to modify this configuration to a 15" Simatic panel
pc talking directly over profibus to the plc, thus removing
the standard pc from the equation.

Basically what i need to know is, are there any pitfalls
that i'm not seeing? I ask because these simatic panel pc's
are quite expensive.

Is there any extra Step7 software required to configure the
panel? I'm currently using Step7 V5.3 + SP3

Can i keep the intouch application (it's quite small) and
still use profibus or do i have to rebuild it in something
like Protool?

Any pointers would be appreciated.
 
There aren't any particular pitfalls as such, other than the price, which as you mention isn't exactly cheap.

Unfortunately the same applies to WinCC Flexible which you will need in order to program the panel.
 
The regular 313C does not have profibus, only MPI on board.
You can use an MPI connection or an ethernet connection (I suppose that there is a CP343-1 in the rack).

I dont understand why you want to switch away from ethernet to profibus.
 
Thanks guys for the responses.

The reason I want to get rid of the standard pc is that
the area it works in gets quite hot and I'm frying pc's.

I'm using Intouch 7.1 which isnt supported in windows XP.
I have got it running on xp alright but I cannot get the
s7 io server software to run in xp. The pc presently runs
Win 2000 Pro.

The new siemens panel pc's, obviously, dont have Win2000
support. Not to say it wouldnt run okay but it might be an
expensive risk.

Therefore, from my limited knowledge, :oops: I thought that
i could maybe talk directly to the plc using an
industrial spec siemens panel.

Thanks Jesper, I'm only now realising that, yes, the 313c
does not have a profibus port. I have an ethernet cp, yes.

So is Wincc the only option?

No there are many many options.

Surely Intouch may also exist in a newer version that support Windows 7. And an IPC rated for hight temp should be possible too.

A Siemens touch panel that connects via MPI or ethernet is a rugged solution.
For Siemens OP/TP177 - OP/TP277 - Compact panels, you need WinCC Flexible 2008 Standard.
I like the new Comfort panels. They are much better than the older panels and less expensive too.
For the Comfort panels you need WinCC Comfort v11.
 
have you gave a look to the siplus line of hmi that support lower and hier temp...making the move you may consider that too

I strongly support what Jesper said. Keep the Ethernet CP, and continue using the Ethernet link. Get rid of the PC, and use a better Simatic HMI.

You'll need to redesign the screens using WinCC flex in any case.

MP377 is a good option with it's 12" screen. Mp277/TP177B will work also. But the smaller screen sizes of these panels may pose some challenge, if the original PC app used very detailed graphics.

KTP1000 would be a nice choice. This display and the software (Simatic Manager 10.5) are much cheaper.
 
How Does a Touchscreen Work?


http://http://www.njytouch.com/view.asp?keyno=647




A basic touchscreen has three main components: a touch sensor, a controller, and a software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system.

1. Touch Sensor
A touch screen sensor is a clear glass panel with a touch responsive surface. The touch sensor/panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the video screen. There are several different touch sensor technologies on the market today, each using a different method to detect touch input. The sensor generally has an electrical current or signal going through it and touching the screen causes a voltage or signal change. This voltage change is used to determine the location of the touch to the screen.

2. Controller
The controller is a small PC card that connects between the touch sensor and the PC. It takes information from the touch sensor and translates it into information that PC can understand. The controller is usually installed inside the monitor for integrated monitors or it is housed in a plastic case for external touch add-ons/overlays. The controller determines what type of interface/connection you will need on the PC. Integrated touch monitors will have an extra cable connection on the back for the touchscreen. Controllers are available that can connect to a Serial/COM port (PC) or to a USB port (PC or Macintosh). Specialized controllers are also available that work with DVD players and other devices.

3. Software Driver
The driver is a software update for the PC system that allows the touchscreen and computer to work together. It tells the computer's operating system how to interpret the touch event information that is sent from the controller. Most touch screen drivers today are a mouse-emulation type driver. This makes touching the screen the same as clicking your mouse at the same location on the screen. This allows the touchscreen to work with existing software and allows new applications to be developed without the need for touchscreen specific programming. Some equipment such as thin client terminals, DVD players, and specialized computer systems either do not use software drivers or they have their own built-in touch screen driver.




Touchscreens Add-ons and Integrated Touchscreen Monitors

We offer two main types of touchscreen products, touchscreen add-ons and integrated touchscreen monitors. Touchscreen add-ons are touchscreen panels that hang over an existing computer monitor. Integrated touchscreen monitors are computer displays that have the touchscreen built-in. Both product types work in the same way, basically as an input device like a mouse or trackpad.

Touchscreens As Input Device

All of the touchscreens that we offer basically work like a mouse. Once the software driver for the touchscreen is installed, the touchscreen emulates mouse functions. Touching the screen is basically the same as clicking your mouse at the same point at the screen. When you touch the touchscreen, the mouse cursor will move to that point and make a mouse click. You can tap the screen twice to perform a double-click, and you can also drag your finger across the touchscreen to perform drag-and-drops. The touchscreens will normally emulate left mouse clicks. Through software, you can also switch the touchscreen to perform right mouse clicks instead.

Infrared Touch Panel

How it works
Infrared technology uses infrared emitter-collector pairs to project an invisible grid of light a small distance over the surface of the screen. When a user touch the surface of screen, the infrared emitted from LED beam is broken ,the absence of the signal at the collector is detected and receiver transmits X-Y axis information to the PC port via touch controller.

Infrared technology is the survivor of harsh applications. It's the only technology that does not rely on an overlay or substrate to register a touch, so it's impossible to physically "wear out" the touch screen. It's an excellent choice for harsh industrial and outdoor kiosk applications.
