ctrlX CORE Selection

[arsz]

Hello Community,

In one of my projects, I will use a ctrlX CORE, with a bus coupler and multiple analogue input modules (20 modules with 80 inputs). I am going to use Node-RED to read inputs, transform data and log into the database. The sampling frequency would not be less than 1s, but one or multiple inputs may have to be read with 500 ms frequency. 

My question would be, that is a rule of thumb when instead of a ctrlX CORE X3 device I should use an X5 or X7. After how many inputs modules or/and sampling rate frequency require bigger calculating capacity? 

Best regards,

Hello,
the X3 will cover you mentioned requirements. ECM will be able to run in default 2ms with the buscoupler.
Please consider to use the configurator go get an first impression and easy access to the datasheets of the modules.
Bye
