2 LOGO's networked

not sure where to post this now! so if this is in the wrong place then mods please move.

i have a program running on a logo which is very good but now i have a new problem to solve....

i will try and explain in simple terms

the logo runs one machine but now we have 2 machines each having a control panel with the logo in and program running independently but now we have introduced a roller shutter door in the middle so when the door is open we want the machine to run has one using all the fixtures and fittings but disable one TDE and run all on of the other TDE i.e master and slave

is this possible via network inputs/outputs etc?

anyone done anything similar?

lol :)

well nearly, 2 machines.

1 master and 1 slave both running independently on there own LOGO and TDE until the roller shutter door is open then it will become one machine and the master logo and tde will control the slave logo and make the slave tde redundant.

The thing is i have data input on the tde for temperature going into a mux amplifier, can these be transferred over because of the nature of the machines i cant have different temperatures etc they will have to be the same for the burner control.

make sense?

Although English is not my native language either but this is what I can make of it:

Machine 1 has its own Logo and TDE

Machine 2 has its own Logo and TDE

These machines run independent from each other. 

When the door between the 2 machines is opened they want 1 TDE disabled and have the controls on the other TDE. I guess the Logo remains active and runs its own program, just the TDE is switched to the other TDE (so extra controls should be available I guess). 

Without knowing details on the program there's not much more I can say, but perhaps this "translation" is a push in the right direction. Of course my "translation" should be confirmed by thedodgy1

Don't know why my native language is hard to understand when its perfectly written by someone else?

anyway, yes that's the general idea above :)

i am able to switch the inputs and outputs via 1 TDE to both LOGO's via network. That part is relatively easy but the one problem i have is that i have some values inputted via TDE for some temperatures and when the door is open and the machine becomes 1, i need only the master sending the temperatures to both mux amplifiers so not to get a mismatch in temperatures from 2 heaters.

i have managed to network everything now including the temperature mux etc. But i am struggling to find a way to get the times from one logo to the other (please see picture) there must be a way of doing this but i just cant see it.

I think you may use time parameter map to local VM address.
