Hi All,

I am currently working on a project that has more that 24 DI so have added a second base unit as a slave for the additional 4 inputs required. I was wondering if its possible to use the 4 remaining inputs, DI 7,8,1 & 2 as analogue inputs on the slave module and use them as NAI.

I've noticed that having set the 2nd base module as a slave it does not give me the option in the settings for the base unit to activate the 4 AI. Does this mean its not possible or is there a work around?

Apologies if this should have gone in the projects thread  !

Many thanks

Rick

Hi ixo65,

I did not realize you could do a master - master connection. Only networked two base units once before and that was a master - slave connection, as advised by local Siemens support.

Quick question, apologies for my ignorance,  when i did a master - slave connection last time i only downloaded the program to the master device, would this be the same for a master - master connection? 

Thanks once again

Rick

Hi ixo65,

i think i understand, but an example would great if possible, i find i learn better working through an example.

Many thanks once again!
