fp-2015
Hi,
Ravens Fan is right, you have to embed in FP-2015 an application, which sends/receives data from serial port. From MAX, you see NI Hardware connected to the PC from which you're running MAX, PCI boards, etc... and remote item, connected through network. You are not able to see cascaded devices connected to FP-2015 serial port (but of course you can see devices backplaned together).
For my application, I use two cFP-2020 (very similar to 2015), which communicate with 2 FP-1001 via serial 485, Optomux protocol. You can use the same libraries you use froma the PC to communicate to FP1000, it changes only that you now run your application in FP-2015.
Remember, if you want to control application from your PC, you don't need Real-Time module, but you need it if you'll want to build a standalone application, runnig in FP-2015.
If you need further infos, I'll be here, I can be helpful since I've already done something like you're trying to do... perhaps I hope!
Have a nice day!

Hi Jacouille,
first of all, if you are french speaker, you can post in french, if you find it more comfortable (or italian, but your nick seems not too italian
).
If I understood, you have to access a distributed IO from 2 PC, right? If so, it is not true that you HAVE to use an ethernet module, you can simply use RS-485 modules, such as FP-1001, since RS-485 is a bus, and with a careful design, you can access the same module from two PCs.
In my application, from 2 cFP-2020 I access 2 or more FP-1001, ie the first cFP-2020 access to FP-1001s, and when it dies the second cFP-2020 access to FP-1001s.
**********
About Optomux, how do you actually access to your FP-1000 modules? I suppose you use FP functions such as the ones used in "Find FP-100x Devices.vi" example. They are Optomux based functions! Optomux is a simple serial protocol to communicate with FP serial devices, but you find libraries in LV for that!
*********
If you have questions... just ask! If you want, post some basic code you use to access your module: it can be useful to understand how you are used to work (I've supposed you doesn't use Express VI, for example, if you use them I have to change a little bit my answers!).
Have a nice day!

Bonjour Jacouille,
Tout d'abord, je m'excuse pour mon francais, mais j'espere tu vas comprendre.
Cable de 2 PC a un FP par RS485:
les 2 PCs sont tout les deux des "master" de communication, donc il faut que les TX soit cable ensemble. Je suppose tu vas utiliser une 485 a 4 fils (ou tu utilise a 2?).
(Tx+ PC1 ) --> (Tx+ PC2) --> (Rx+ FP)
(Tx- PC1) --> (Tx- PC2) --> (Rx- FP)
(Rx+ PC1) --> (Rx+ PC2) --> (Tx+ FP)
(Rx- PC1) --> (Rx- PC2) --> (Tx- FP).
On principe, le bus 485 c'est fait pour une reseau "mutidrop", c'est a dire 1 Master, plusieurs slaves, mais tu peux connecter 2 master, si seulement l'un des deux gere la communication. Bien sure, on peut pas avoir 2 PC qui communique avec le FP au meme temps....
Dans ma application,les 2 PC accede au FP soit l'un, soit l'autre, pas au meme temps, mais j'ai de meme essaye de faire communiquer les 2 PC ensemble, et ca marchait.... mais c'est pas deterministe, comme essay.....
**********************
Si tu pense que ca va pas marcher, comme ca, c'est une bonne idee d'utiliser tout de suite Ethernet, si non tu vas avoir un systeme pas "scalable". Donc, mon avis c'est de voir si tu peux avoir un remote panel sur 2 PC, qui acced au meme FP. Si oui, je pense que c'est tres facile avoir plusieurs PC qui controle le meme FP. C'est tres facile a configurer, tu peux emposter (se dit comme ca?) la liste des PCs qui peux acceder au FP, tu peux acceder de un site loin, et tous les advantages des reseaux LAN/WAN... est ce que tu connai deja cette option (remote panel )?
J'espere pouvoir etre utile, pardonne moi pour l'ortographie et la longeur du post
.... a bientot!
