[Beeping USP-104-B10 on start-up]

I bought a USP-104-B10. I took it out of the box and applied power. After starting up it displayed a message saying the program that is loaded requires an SD card and gave me the option to retry or ignore. Since I was going to load a program that didnt use one. Now it just restarts after idling at the unistream logo and beeps. What can I do?

[Differential Input Signal]

Is there a module for Unistreams that can provide a +-10v differential signal?

[Connecting to expansion modules]

Hello,

 

I am planning to buy a V1210-T20-BJ and mount it in a panel door. I want to connect it to 3 x IO-DI16's and 3 x IO-TO16's that will be mounted on a din rail inside the panel. What is the module I should use to connect them and what cable should I use?

[USP-104-B10 Capacity]

I was reading this document for the USP-104-B10. It says it can hold up to 5 modules. I have never used one of these and would like to know if the CPU consumes some of these slots.

I am hoping I can fit a USC-P-B10 and three UID-W1616R onto one USP-104-B10.

 

Other wise  I will have to get an extension module and am not sure which one to get at the moment.

Thanks
