Writing in between daily work activity
Started from the moment when I attended released product conference from one of automation vendor in Jakarta. They showed demos and some presentation related to profinet system and the functionality of profinet which they said it as “next generation” communication protocol based on ethernet. I’m very interested when they showed one of feature from profinet IO i.e exchange data between master CPU PLC with short and flexible way. Why I said that short and flexible way ? Because it just click, configure, and it can be used directly to other station without scripting to buid connection / communication 
By trying a few times, I find how to generate I-Device
Below some requirements which we need :
- Simatic Manager v5.5
- Firmware CPU Profiner v3.2
Firstly, we should know what is functionality of I-Device ?
I-Device or Intelligent IO Device allow data to exchanged with an IO Controller (PLC). I-Device is connected to higher level IO Controller as IO Device or remote IO. Let see this chart :
I-Device has many advantages :
- Simple connection of IO Controller without additional tool
- Real time communication between S7 CPU
- Manage processing of subtask in separate Step7 project
- Lower communication loads by process data locally
- Required computing of the individual CPU or IO Controller can be reduced
Next, directly I want to explain how to create I-Device which steps :
Configure hardware config Simatic 300 station
Configure PN-IO and activate I-Device Mode at I-Device Tab
Map datas that will be shared (input or output)
Generate GSD File
Export GSD File to Folder
Using GSD File in Other Station / IO-Controller
Logic Script at IO-Controller Side
Logic Script at I-Device Side
The address of transfer area are preset by HW Config, as usual can be changed by user. In this case, Q 100.0 was specified for the transfer area.
Finally !! just it how to create and use I-Device that can we use to exchange data between CPUs. I-Device is one of many function profinet, other functionality of profinet i.e option handling, device replacement, prioritized startup, docking station, shared device, Isochronous mode, PROFIenergy, web base system, and media redundancy.

i-Device itu Intelligent Device ya?
adakah relasi dengan iPad, iPhone, dan i i yg lain?

hehehe ga ada lah
itu istilah dr siemensnya aja gt
gimana SI mas ?
jangan2 belon punya lagi v5.5, mau dikirimin ?

Mantabbb….. Harus Segera di applikasikan ni… Zara 2 Harus udah pake Profinet Semua Kalo bisa… he..he..
March 21st, 2011 at 12:30 pm
zara 2 kagak mungkin, mau rugi brapa ntar

… tolong cari cara gimana carana agar Profinet kepake tanpa menggangu dia sbg NTP Client ..:D

hahahaha ga bisa euy mas, firmware terbaru juga kagak bisa, sekali profinet io masternya diaktifin pada ga bisa jadi slave
ya paling kayak yg dulu itu pake script 
atau kalo mau agak mahalan tambah CP ethernet khusus untuk ke SCADA dan time sinkron :p

Acara apaan Mas di Jkt ??? di JW Marriot pa bukan yah ???

yup,,,,,,

thanks for the short tutorial. Know i understand what I-Device is.
It seems similar with PLC communication between Marine and Sampler PLC on my work place, but it use Profibus.
March 27th, 2011 at 1:44 am
totally different, mas layudhi :
- Sampler cannot create GSD file which can be called or installed at Marine side/project
- Sampler and Marine communication still need scripting, but in Profinet I-Device we just share data in HWConfig

thanks for the correction Mister

Have you ever thought about including a little bit more than just your articles? I mean, what you say is important and all. However just imagine if you added some great graphics or video clips to give your posts more, “pop”! Your content is excellent but with images and videos, this site could definitely be one of the very best in its field. Terrific blog!
