s7 with mitsubishi

Hi Folk,

Is Mitsubishi PLC support Profibus?

I am going to link up S7 300 and Mitsubishi PLC.

what is different between normal i/o and Fail safe i/o for s7?

regards

Hell teh;

I know of Q02H CPU with a Profibus QJ71PB92D profibus module; probably other CPU families of Mitsu have their own Profibus processors, as Mitsu states that it supports it on their advertising.

Failsafe I/O are used in conjunction with Safety PLCs (Siemens F-CPUs, Rockwell GuardPLC) to allow the setup of SIL-2 or SIL-3 safety levels in automated systems. They are specially designed to allow 1oo1 or 1oo2 voting schemes at the I/O level. The following image shows wiring diagrams for 1oo2 voting, and the safety level SDIL-3 they can procure:




This, by the way, is from a manual "Safety engineering in Simatic S7" you can find on Siemens' support website.

Hope this helps,

i have simatic manager v5.3 sp3, do i need additionl software for implement Fail safe system?

Hello Teh;
I am no longer at the office, so I don't have all the details you want. Note that all the required info is in the manual I suggested, and in the manual "Distributed Safety".
In the Siemens world, there are Safety-enabled CPUs, capable of compiling, validating and running safety programs; they are designated as F-CPUs (315-2-F, 414-HF, for example). There are Safety i/O (the SM 326 mentionned in the illustrations above is an example). There are Safety extensions of Step 7 (with hardware catalogs including Safety CPUs and I/Os) and contaning the programming extensions for Safety programs and validations. And finally there are Safety Run-time licenses that you have to install on the Safety CPUs when they are actually controlling a Safety application.
Part numbers should be available in the manuals above, if you require them.
Hope this helps,
Daniel Chartier
