Hi. As I said before, this is my first time working with PLCs from SIEMENS.
The project I'm working with includes a subnet profibus for getting some data from some slaves distributed all over the camp. Three of this slaves were not programmed for us (our team) cause they came as part of some Gas Analyzers, programmed in Germany.
I need to get into my S7-300 master the state of some OUTPUTs and INPUTS (including Analogic Inputs) from this slaves (S7-300 too)
Can some one explain me What functions can I use to get the value of this signals (the analogic ones) and the state of the digital ones (can I read the state of the outputs too?)?
I would thank if you indicate me where can i find some examples about addressing slaves' modules in a profibusDP network.
